TestRail-Test Case Management Tool.

TestRail is a comprehensive web-based test case management software to efficiently manage, track and organize software testing efforts. Its intuitive web-based user interface makes it easy to create test cases, manage test runs and coordinate the entire testing process. Track and follow the status of individual tests, milestones and projects with dashboards and activity reports. Get real-time insights into the testing progress and boost productivity with personalized todo lists, filters and email notifications.

Getting started with TestRail

TestRail allows team members to enter test cases, organize test suites, execute test runs and track their results, all from a modern and easy to use web interface. Teams benefit from four main advantages when adopting TestRail:

  • Manage test cases, suites and test runs
    The traditional way of managing and documenting test cases on paper, in wikis, bug tracking tools or general document management systems quickly reaches its limits. TestRail enables you to create, manage and organize test cases and suites within an optimized user interface and application structure.
  • Boosting testing productivity
    TestRail’s todo lists, filters and email notifications help coordinate test runs and increase the productivity and responsibility of testers. The goal is to make sure that every team member knows his tasks at all times and that team leads can assign new tasks to testers depending on their workload.
  • Real-time insights into your testing progress
    To make important project decisions, it is critical to have access to detailed information about the testing progress and test results. Questions such as “How many percent of a test run have we successfully completed?”, “How are we progressing on the upcoming milestone?” or “Which tests have been executed in the past 24 hours?” can only be answered efficiently by using a comprehensive test case management software such as TestRail, and TestRail makes these details readily available.
  • Organize and track software testing efforts
    The organization and coordination of multiple parallel tests, be it for different projects or releases, is often complex and time-consuming. To not lose track of your testing efforts, TestRail helps you manage important software-specific data and structures such as project milestones and makes it easy to integrate with bug tracking tools.

The dashboard

After logging in to TestRail, the first page you usually see is the dashboard. The dashboard provides you with an overview of available projects, recent project activities and your todos. When you navigate to a project (by clicking on a project title), you switch to the project view and land on the project’s overview page, showing project details such as test suites, active test runs, project activity and so on. Whenever you need to switch to another project, just return to the dashboard by clicking the link in the upper left corner.

Test cases and suites

A test case in TestRail consists of a description of the test’s prerequisites, a list of test steps and the expected result. A test case can ideally be verified by a single tester in a short period of time and confirms a specific functionality, documents a task or verifies a project artifact.

In TestRail, test cases are organized into test suites. A test suite is a collection of test cases and is often created for specific project modules or areas. How you organize your test suites depends on the size of your project. If you have a lot of test cases for a project module, it is recommended to further break down your test suites and create suites for specific features or functionality. Ideally, a test suite consists of 50-1000 test cases.

Test runs and tests

To run a test and enter test results for the cases you added, you start a test run for a particular test suite. While a test suite is just like a plan that specifies how an application is tested, a test run is an actual test you are conducting.For most projects you will most likely start multiple test runs for a particular test suite over time. For example, if you are releasing multiple versions of a software program, you might want to conduct a test run for each new release. Likewise, you can have multiple test runs for a particular test suite active at the same time. This can make sense if you want to execute a particular test suite for multiple configurations (such as different operating systems). You can then start a test run for each different configuration you want to test against.

The following test statuses are available by default:

  • Untested
    By default, new tests have the status Untested. Once a test result has been added to a test, it can never receive the Untested status again.
  • Passed
    A test is marked as Passed when a tester verified the test steps and the expected results.
  • Failed
    A tester marks a test as Failed if one of the specified test steps resulted in an error or if the expected result differs from the actual test result.
  • Retest
    If a developer or tester determines that a test should be tested again, she marks the test as Retest. E.g., if a test originally failed and the developer fixed the problem, the developer can mark it to be retested.
  • Blocked
    The Blocked status is used to signal that a test cannot be executed currently because of some external dependency (such as a bug that needs to be fixed before being able to complete to test). It is often used in combination with the Retest status.

Projects and milestones

Projects are the main organizational unit in TestRail. It is generally recommended to create a TestRail project for every real software project you want to manage within TestRail. All other data such as test suites, runs, test results, milestones etc. are directly associated with a specific project. See the following illustration to see how the different entities relate to each other:

 

You can also add your project milestones to TestRail. A milestone can be any project milestone you deem to be important, such as a planned public software release, an internal test version or a new beta release for an important customer. Once you have added your milestones to TestRail, you can assign test runs to specific milestones

Test plans and configurations

When you need to manage multiple test runs and configurations for a single project, TestRail’s test plans come in handy. A test plan allows you to start multiple test runs at once, either if you have many test suites or if you want to test against multiple configurations (where a configuration can be anything you need to test your project against, such as different operating systems or web browsers).

 

To create a test plan, simply click the Add Test Plan button from the Test Runs & Results page. Now just select one or more test suites from the sidebar to add them to the plan. Just like you do with a single test run, you can configure all properties of the test runs such as the name, the cases you want to include and so on.

 

 

To dos and notifications

Tests can be assigned to team members. You can either assign tests when a run is created or do so afterwards from the run or test pages. Once a test has been assigned to a user, the test appears on the user’s todo list. Every user has its own todo list for each project she’s working on, while the Dashboard provides a quick way to see the user’s todos for all projects. The todo page can also be used to view the todos of other team members or the entire team at once, providing an easy way for team leads to assign tests to team members with the least workload.

 

Another relevant feature are email notifications. Email notifications help test owners to learn about test changes made by other users. For example, if a test has been assigned to a user (i.e. the test owner) and another user adds a comment or result to the test, the test owner is notified by email. It is also possible to subscribe to tests of other users or even entire runs by clicking the small email icons on the relevant pages.

Tracking progress and activity

Besides making it easier to manage test suites and enter test results, providing an easy way for all team members to track the test progress is one of TestRail’s most useful features. You can view the test results and testing activity of runs, milestones and entire projects on the individual resource pages.

 

You can choose between the status, activity and progress view on the test run and milestone pages from the sidebar, while you can switch between the project history and test results on the project’s overview page. Additional reporting features can be found on the Reports tab

How to Become a Great UI, UX Designer in 5 Easy Steps.

1. Know the basic abilities & responsibilities of UX/UI designers

Almost everyone can become a UX/UI designer by self-taught or training course. However, when it comes to how to become an excellent UX/UI designer, it requires not only basic design capabilities but also some necessary abilities, including the ability of logical thinking, data analysis, empathy, communication, observation and agile execution, etc. To get to know the designer’s responsibilities and skills is the first and foremost thing to some degree.

2. Capture the eyes and heart of your users

Be a UX or UI designer, the final deliverable needs to capture the user’s heart. If a user doesn’t have the desire to use the product, there is no user experience at all, not to mention the user engagement and conversion. For UI designer, it needs to focus on the beauty of the design work; while for UX designer, it needs to care about the user’s demands and product functionalities. Just like an old saying goes that “Practice makes perfect”, to become an excellent UX designer or UI designer requires continuous efforts.

3. Be concerned about the UX/UI design trends

Many job seekers who want to step into the UX/UI design industry will be asked about “how do they think about the current UX/UI design trend” and some other similar questions during the interview. To keep updated with the newest UX/UI design trends can make your design work outstanding and meanwhile let you become a UX design expert.

4. Be proficient in certain design tool

Not a few beginners have their own ideas, innovations, and indulgences, while they tend to ignore the proficiency of design software tool. Undoubtedly, the design tool can be a great helper for designers, and it’s required to make simple icons/pictures in the interview to test the basic design skills of candidates. Below are some tools recommended for those want to become a UI design expert:

  •  Adobe Photoshop:-  A raster graphics editing tool
  •  Adobe Illustrator:-  An vector drawing tool

ERP Software Testing

Testing the ERP (e.g SAP) software application is different than testing the other software applications. ERP applications are domain specific and industry-specific. The common modules like Finance, Accounting, Inventory, Fixed Asset, Sales, Purchase, Human Capital, and Payroll are available in all the ERP systems.

Apart from these common modules, few industrial specific modules are available as per the targeted customers. For example, a “manufacturing ERP” may have a “production planning” module, a “pharma ERP” may have a “doctor-patient” module and an “education ERP” may have a “student” module and so on.

So we can take a example of One Module.

Test Scenario: Find below a sample ERP demonstration.

Virtual Assistant

A virtual assistant is a software agent that can perform tasks or services for an individual. Sometimes the term “chatbot” is used to refer to virtual assistants generally or specifically those accessed by online chat (or in some cases online chat programs that are for entertainment and not useful purposes).

As of 2017, the capabilities and usage of virtual assistants is expanding rapidly, with new products entering the market. An online poll in May 2017 found the most widely used in the US were Apple’s Siri (34%), Google Assistant (19%), Amazon Alexa (6%), and Microsoft Cortana(4%). Facebook’s M is expected to be available to hundreds of millions on Facebook Messenger in 2017.

 

Cortana

Cortana is an operating system-oriented voice assistant available on Windows 10 devices, as well as the Xbox One console. Cortana is closely connected to productivity, but can also help answer more general questions by pulling information from Bing.

The Cortana VA has seen a lot of recent growth, expanding her use throughout Windows 10 and related services. Combined with newer offerings like Surface Studio, its clear Microsoft favors Cortana as an OS-based service to control Windows 10 while one is working.

While user can store specific bits of information with Cortana, Microsoft’s virtual assistant is constantly analyzing user’s interactions to learn more about him/her. This info is stored in something Microsoft calls the “Notebook,” which includes the places user likes to go, people he/she care about, user’s preferred quiet hours, and things he/she might be interested in, among other things. User can even edit it if he like.

Cortana can user’s emails, track user’s location, watch user’s browsing history, check user’s contact list, keep an eye on user’s calendar, and put all this data together to suggest useful info, if user allow it to. Cortana is designed to recognize context, so it should be able to understand follow-up requests, and you can phrase things in different ways and still expect a useful answer. User can also type his/her questions or requests, if you prefer to not speak out loud.

The latest changes from the Windows 10 Creators Update allow Cortana to help in the setup process for new computers, and include a new full screen mode for Cortana that serves as both a screensaver and voice-assistant focused mode when user is away from the computer—or is too far away to type. Cortana can also handle music and reminder commands more effectively, spanning multiple music apps and controlling volume as user desire.

 

Siri

Siri has been an integral part of iOS since the launch of iOS 5 in 2011. It started with the basics such as weather and messaging, but has expanded greatly since then to support more third-party integration with MacOS.

While Siri’s jokes are legendary, the virtual assistant is getting more capable every day. Now, user can ask it to call people, send messages, schedule meetings, launch apps and games, play music, answer questions, set reminders, and provide weather forecasts.

Siri can also integrate with third-party apps and understand follow-up queries. That’s a big change in strategy for Apple, which typically maintains a tight grip on which third-party companies get access to its native functions.

Siri is probably the most familiar of all the voice assistants. It also lags behind the other VAs when it comes to text input, which isn’t supported for most Siri functions. Apple appears to be using Siri for voice controls and Spotlight for similar text-based queries.

The latest news for Siri includes voice compatibility for WhatsApp, expanded payment options for Lyft and Uber, and the ability to look up international cricket scores. These are minor tweaks compared to the changes other VAs are going through, but they also point to Siri’s continued stability—particularly for long-term iOS users who already know the voice assistant well.

 

Google Assistant

Google Assistant (which has incorporated functions from the older Google Now, as Now is being phased out) is different from Cortana and Siri. It has less personality, but more functionality. While it is an integral part of Android, Google Assistant also lives in an iOS app, and can be accessed through the Chrome browser as needed.

Like Cortana and Siri, you can ask Assistant for directions to the closest Chinese restaurant, or what the weather looks like for the next 10 days. If you let it, Google’s software will utilize your search history and customize its responses based on what it knows about your queries.

Google’s integration with its search engine makes Google Assistant one of the most useful virtual assistants out of the box. It already has a treasure trove of data on what you’ve done on the web. It also reacts to questions in a similar way to the Google browser, which makes it great for general information and trivia.

 

Alexa

It is Amazon’s voice assistant and it isn’t focused on mobile or computer purposes, but rather for the standalone Amazon Echo speaker and a limited number of Amazon Fire devices, with a greater concentration on whole-house management and services rather than computer-oriented tasks.

Obviously, this limits Alexa compared to the alternatives. However, there are some advantages to the Amazon approach. Like Assistant, Alexa is highly conversational, and its ability to parse meaning is frequently excellent, whether you’re asking about the weather or listening to the latest news summaries from around the web. Alexa is meant to be used out in the open, away from the computer, while you’re working elsewhere but still need information, entertainment, or purchases.

The customization and management options for Alexa also impress. While other voice assistants hide many of their capabilities away from users, Alexa brings them all out in the form of “skills” and connections. The Alexa app allows you to add various mini-apps in the form of skills, and adjust current services and settings using these skills. It’s a great system, especially for those who like to tinker, but it does require learning a new approach to VA management.

Amazon is also doing a lot of work to bring Alexa into more mobile situations: The Alexa app, for example, brings many of its capabilities to your phone so you can organize lists while driving or control smart home features away from an Echo.

 

 

Bixby

Not to be outdone in the voice assistant game, Samsung has also created a mobile device assistant called Bixby, which now has full voice command compatibility (if you’ve picked up a Galaxy S8, you’ve probably encountered it). In general, Bixby shares a lot in common with Cortana. The VA lingers on the Galaxy phone, ready to access information and manage your data, schedule, events, and more. It doesn’t venture out into the Internet of Things much, but it does have an impressive amount of control over everything you do on your Samsung device.

You can divide Bixby into three basic different categories of abilities—Voice, Home, and Vision. They all work together, but use different Bixby abilities:

Voice includes both questions—”What’s the weather today?”—and commands. Start by saying “Hey Bixby” and you can get general information or facts. However, like Cortana, Bixby also excels at operating software, so you can also use it to control the Galaxy menus, change settings, set reminders, take pictures, edit video, and much, much more. If you’ve ever wanted to operate your smartphone hands free, there’s a lot to explore here. Some functionality goes even deeper – you can ask Bixby to read out your latest emails, or tell it to post your photo to Instagram, and Bixby will do so.

Home is the app face of Bixby, a screen that provides information based on what you have asked Bixby about in the past, as well as the different services that Bixby can control with the right compatibility—Including Facebook, CNN, and Spotify. In the future this area may include smart home capabilities (Samsung says it’s on the way), but for now it’s relegated to basic online services.

Vision is the most unique part of Bixby, as it can analyze what image the camera is picking up and give you a report on it. When this works (say, looking at a recognizable logo) Bixby can help you instantly compare online prices to in-store prices, or give you more information about local landmarks. If this feature takes off, other voice assistants may start getting jealous.

 

 

Working with Calabash

Hi All,

Now we know how to install and run Calabash and its all requirements and prerequisites.

Now let’s see how to work with it.

Open the “calabash-android-0.9.0” folder. It resides at path C:\Ruby23\lib\ruby\gems\2.3.0\gems\calabash-android-0.9.0. The folder names will change in synch with the ruby/ calabash version you install on your machine.

Open the feature skeleton folder. Look out for this basic framework.

  • The *.feature file contains scenarios that we are going to automate.
  • The method used by the feature file is written in *.rb file inside “step_definitions” folder.
  • Common methods, environment setup, app installation and hooks should be placed inside “support” folder.

Resign & Build the app

  • Calabash-android resign *.apk
  • Calabash-android build *.apk

Attach the device to the system /Open the emulator

Check device attached. Type command >>adb devices

Attached devices list should be displayed.

How to Find the Element Locator

  • Open the console. Type the Command.>>calabash android console “APK Path”>>start_test_server_in_background
  • Above command launch the app on the device. To find the element locator use following command.>query “*”

Creating New Scripts

Open the feature file and following lines

Feature: Login feature
 Scenario: As a valid user I can log into my app
 When I press "Login"
 And I enter my username 
 And I enter my password
 Then I see "Welcome to coolest app ever"

Open the Step Definition file & Define the method into *.rb file.

Given /^I am on the login windows$/ do
 wait_for(:timeout =>100) { element_exists("* id:'loginInput;")}
 check_element_exists("* id:'loginInput;")
end.
Now you can automate your UI testing using the Calabash.

Geofencing

Geofencing is the use of GPS or RFID technology to create a virtual geographic boundary, enabling software to trigger a response when a mobile device enters or leaves a particular area. The use of Geofence is called Geofencing.

It requires Location aware device of a location-based service (LBS) user entering or exiting a geo-fence. This activity could trigger an alert to the device’s user as well as messaging to the geo-fence operator. This info, which could contain the location of the device, could be sent to a mobile telephone or an email account.

The technology has many practical usages-

  1. Network logs can record geo-fence crossings to document the proper use of devices and their compliance with established policies.
  2. An ankle bracelet can alert authorities if an individual under house arrest leaves the premises.
  3. When the home owner’s Smartphone leaves the home’s geo-fenced perimeter, the thermostat lowers itself to a pre-defined temperature.
  4. A network administrator can set up alerts so when a hospital-owned iPad leaves the hospital grounds, the administrator can monitor the device’s location and lock it down to prevent it from being used.
  5. An employee’s smart card will send an alert to security if the employee attempts to enter an unauthorized, geo-fenced area.
  6. A sporting event can use geo-fencing to create a temporary no-fly zone that prevents drones from crossing a defined perimeter.
  7. Geo-fencing can alert a dispatcher when a truck driver breaks from his route.
  8. Small businesses can text an opt-in customer a coupon code when the customer’s Smartphone enters a defined geographical area.
  9. An ankle bracelet can alert authorities if an individual under house arrest leaves the premises.
  10. An airline app can define a Geofence around an airport when a flight reservation is near boarding time. When the device crosses the Geofence, the app can send a notification that takes users to an activity that allows them to get their boarding pass.

 

Automation testing Using Calabash

Calabash is one framework that enables automated UI Acceptance Tests written in Cucumber to be run on iOS and Android applications. While Calabash integrates tightly with Xamarin.iOS and Xamarin. Android project, it can also be used with iOS and Android projects written in the indigenous languages of Objective-C and Java.

Calabash is an open source Acceptance Testing framework that allows you to write and execute tests for iOS and Android Apps. It’s an Automated User Interface Framework that allows tests to be written in Ruby using Cucumber. Calabash works by enabling automatic UI interactions within an application such as pressing buttons, inputting text, validating responses, etc. It can be configured to run on different Android and iOS devices, which provides real-time feedback and validations.

Calabash and BDD

  • Calabash is Behavior Driven Development (BDD). It is same as Test Driven Development (TDD), but instead of creating tests to describe the shape of APIs, application behavior is specified.
  • BDD is a process in which multiple stakeholders weigh in to create a common understanding of what has to be built.
  • BDD is helpful in building the right software and designing from the perspective of the business owner.

ERP Software Testing

ERP stands for (Enterprise Resource Planning). In ERP software we can performed various types of testing like Functional Module Testing, Integration Testing, Performance testing & so on.Before testing the ERP as a whole, testing the individual modules is the first step in any comprehensive ERP test. Once the modules have been cleared, then “assemble” and test the ERP. This testing phase is often referred to as “Core testing”.
In Integration Testing Once the core ERP software has been thoroughly tested then you can move on to integration or implementation testing phase. In this phase combine all modules together which is dependent to one another. The goal is to see whether the system delivers the expected results.
Once the ERP has been integrated and tested, it’s time to see how well it performs under load. It is necessary test the ERP using high volume data flow and challenging transactions. In this way we can test the software through various phases.

Reading Mind Technology

Reading Mind Technology

What if Mind reading turns out to be a reality then days are not too far when our Smartphone will not of any use. Because then people would be able to connect with others through their minds. It is not fake but reality that many scientists have been working towards decoding the mind and thoughts of human.

Researchers and scientists have already achieved the success in understanding the Physical structure and chemical workings of the brain and now they are after solving the mysteries to understand the intent of the human, what people dream about and what makes them psychopath. I would like to throw some light on the kind of researches and inventions that have been done past years which are contributing towards decoding the mind and thoughts.

 

Researchers from University of California, Berkley have invented a Brain Decoder Device. This brain decoder device is able to analyze what you are thinking based on neuron activity inside the brain. Researchers have invited the tests subjects to read a passage of text out loud and then reading the same passage in their mind and then they compared the brain activity to look for the linked patterns.  If the technique gets further improvised then it can become boon for those who have lost their ability to speak.  And with the power of mind working wonders, we will be able to control the devices such as Smartphone, computers and other devices with our mind. “If you’re reading text in a newspaper or a book, you hear a voice in your own head,” the University’s Brian Pasley told New Scientist. “We’re trying to decode the brain activity related to that voice to create a medical prosthesis that can allow someone who is paralyzed or locked in to speak.” Pasley and his team based their work around the hypothesis that hearing words in our head causes the same kind of brain activity as hearing them spoken. The sophisticated hardware is under developmental stage and requires being more accurate so it can be utilized out of the lab. The subject is observed carefully and algorithms underpinning the system vary from person to person.

Even Japanese researchers are not behind in evolving this technology. They have developed the mind reading device as well that decipher words from brainwaves without them being spoken. They were able to identify the words such as ‘goo’, ‘scissors’ and ‘par’ when spoken in Japanese. They can identify the brain waves related with syllables or letters hence ensuring the possibility of decoding entire words and sentences without the need for any of them being physically spoken. Researchers used a method to listen to the unspoken word called Electroencephalogram or EEG. The technology records the electrical activity from the brain using an array of electrodes on the scalp to detect the brain waves. The team focused on a part of the brain known as Broca’s area, which is thought to be involved in language processing and speech. Lead author Professor Yamazaki Toshimasa, an expert in brain computer interfaces at Kyushu Institute of Technology in Japan’s Fukuoka Prefecture, and his team asked 12 men, women and children to recite a series of words, measuring their brainwaves as they did so. They found each syllable produced a distinct brain wave activity from the initial thought to the actual utterance. Activity could be seen up to two seconds before a word was spoken. By compiling a database of different sounds, the researchers found it is possible to match these brainwave patterns to words, even if they are not spoken.

Not only this, scientists are developing the technique to control the channels on your TV. For this, they are developing headsets that can read your brainwaves to change the channels.

Researchers from Birmingham University have devised a way to verify the person’s identity 2 years ago. The researchers observed the brain signals of 45 volunteers as they read a list of 75 acronyms, such as FBI and DVD, and recorded the brain’s reaction to each group of letters, focusing on the part of the brain associated with reading and recognizing words. Turns out, participants’ brains reacted differently to each acronym — so much so that a computer system was able to identify each volunteer with 94 percent accuracy.

Yukiyasu Kamitani and his team at ATR Computational Neuroscience Laboratories in Kyoto, Japan, have been able to identify what subjects were dreaming about. They use fMRI (functional MRI), which measures brain activity by picking up on the magnetic properties of hemoglobin that vary with blood oxygenation. Scientists have made some startling breakthroughs in reproducing our thoughts on a screen and delving into what motivates us to do the things we do. The subjects are put into fMRI machine and woken up just as they were drifting off. They then reported what they had been dreaming about. A database was created from the information, and using machine-learning algorithm and a visual-imagery decoder, scientists were able to identify what the subjects were dreaming about in subsequent scans.

Can you imagine that your imagination can also be traced on the screen? Participants imagine forming letters and recorded the patterns of their brains made while they did it. Researchers used this information along with the algorithms and translated it into Pixels thus they were able to reconstruct the actual images of the Participants imagination.

fMRI technology has even enabled researchers to understand the People’s reaction towards the specific products without even their need of uttering the words. The company uses fMRI to assess their feelings about products, packaging, advertising, and even smell.

Defense Advanced Research Projects Agency (DARPA) is funding an initiative where they can hack the mind of the veterans and service members and help them in treating their mental illness and addictions.

Since reading mind is taking a shape of reality, there are few things that we should consider from right now and even start researching on it. It is security of your thoughts, your imagination. In the near future, we may have to find the potential way to secure our mind from unwanted access to information that we have in our mind. I do not blame on technology as it has many advantages if used in proper way but I can blame those users who can misuse it. The technologies like fMRI enable the researchers to understand patterns of prefrontal cortex activity before they took the action, were able to decode what they were about to do. That means in future someone can understand our intent even before we perform any action. It will more become spying on our secret thoughts and our thoughts will no longer be private. Our mind is full of innovative ideas and one would never want that someone hack or decode those ideas for their own benefit.

I think it’s a high time that techies & researchers must also start thinking about solution that can secure our valuable mind against misuse of such technologies.

Steps to perform Black Box Testing Methodology

Hi, friends today we will learn Black box testing, this is a very useful testing technique in Software testing. In this technique we give input and get output without knowing how the output is generated. Black box testing is also called as Behavioral testing.

Methods of Black box Testing:

Error Guessing:
In this technique we randomly put any values not fixed values, and get output. It is not the best practice to use Error guessing method always since it may not cover all the scenarios of the black box testing, white box testing then comes to play. In this post I won’t be covering the white box testing methods.

Boundary Value Analysis:
In this testing we provide boundary values. Suppose our Input should be range 1 to 10 then we test it with -1 , 1 , 2 and 9,10,11. It reduces our testing scenarios since values ranging from 1 to 10 will always work in the worst case scenario.

Equivalence partitioning
Equivalence partitioning  is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In principle, test cases are designed to cover each partition at least once.

 

In the next post I will talk about white box testing methodology. If you like this post share it with your friends.
