What is black box testing? How does one perform it? What are some techniques for performing black box tests and examples of common cases? This blog post is geared towards QA testers who want an introduction into Black Box Testing techniques, and its different types. After reading this blog post, you'll be able to understand which technique would work best for your project based on its requirements.

What is Black Box testing

Black Box testing consists of three main types as following:

  • Functional testing: this type focuses on doing testing based on functional requirements of an application.
  • Non-functional testing: it is used to test other aspects to improve an application's performance, security, or usability.
  • Regression testing: Black Box testing can be used to check if a new code or change will not impact the whole system.

How to do Black Box testing

The Black Box testing can be a powerful technique if it is well-prepared and carried out as following steps:

  1. Firstly, testers need to understand the requirements and specifications of the application. Software Requirements Specification (SRS) is strongly recommended being established in this step.
  2. To save time and achieve good test coverage, testers should select valid and invalid input for both positive test scenarios and adverse test scenarios.
  3. Develop test cases to cover a maximum range of inputs.
  4. When test case execution is performed, it will provide outputs that will be compared with expected results. Then, the test case will be marked as pass or fail.
  5. The final step is to retest the whole system with other testing techniques to verify it works as expected.

Black Box vs White Box testing

The black and white box testing techniques may be used along with exploratory testing to make it more effective. Read our guide to Exploratory Testing.
