The entire process of software development lifecycle includes several steps and stages. Ensuring that the software app being developed is free of bugs, code errors and technical glitches are crucial for a quality assurance professional. There are several ways of conducting software testing including Black Box Testing. Here you will get a glimpse into Black Box Testing.

What is Black box Testing?

Black Box testing is one of the most common and popular methods of checking a software app for the presence of several issues that surface at the time of development. It is done without knowing the internal structure of the code program. This testing technique is what most of the quality assurance professionals perform and used the majority in day-to-day life. 

Software under test, in this case, is known as ‘Black-Box’. Without checking the internal structure of the code, testing of software app is done. The entire testing is performed from the customer’s viewpoint. While testing, software tester knows about the inputs and desired results, what they do not know is how the application or software is actually processing the inputs and giving outputs. All the test cases for testing using this technique are calculated based on the specifications and requirements.

The primary purpose of BlackBox Testing is to check whether the particular software app is working as per the expected standard mentioned in the requirement document and if it is meeting the user expectations. 

We all know that different types of testing methods are used in the industry. Each testing type has its own advantages and disadvantages. Fewer bugs and other issues cannot be identified using the white box or blackbox testing.

Listed below are the blackbox testing types used for testing software applications.

  • Decision table based testing
  • BVA – Boundary Value Analysis
  • Error Guessing
  • Equivalence Class Partitioning
  • Cause-Effect Graphing Method
