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 partitioningĀ  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.
