Black Box Testing: Types and Techniques

Black box testing avoids the need to look at the code structure, and test the functionality of the software under test. Moreover, it also avoids the need to have knowledge about the implementation details and is based on software specifications and requirements.

The prime area of focus remains on the inputs and outputs of the software system. Any system can act as a black box to test. It could be any custom application or OS or browser. Here, only inputs and outputs are required to test the system without involving internal code.

Black box testing also caters the need to test the application based on programming language like Java. We can say that Java Black Box testing can help cover the maximum code using black box test cases.

Steps to Perform Black Box Testing

You can perform any type of black box testing by following the below steps.

  1. Examining specifications and requirements in the beginning stage
  2. Choosing valid inputs (involving positive and negative test scenarios) to check the SUT response
  3. Determining expected output based on the given output
  4. Constructing test cases with selected inputs
  5. Executing test cases
  6. Comparing actual outputs with the expected outputs
  7. Defects are fixed and retested

How Black Box Testing is Different from White Box Testing

Black box testing has a life cycle of its own, commonly known as Software Test Life Cycle (STLC).
