Software Testing - Depth Testing

Testing is all about verifying every component of the software and ensuring its quality. It is one of the most important steps in the software development life cycle (SDLC).

What is Depth Testing?

The depth testing is all about verifying the functional and non-functional requirements of the software in depth. It is a very detailed testing approach to verify the functionalities of the software is tested. The defects detected during the depth testing phase are logged by the testers. It is normally done along with breadth testing.

Practical Example of Depth Testing

Let us take an example of an application which does the addition of two numbers. The depth testing includes the scenarios listed below −

  • If the software gives the correct addition of two numbers.
  • Check how the software behaves with infinite number addition.
  • Check how the software reacts with negative numbers addition.
  • Check how the software deals when non-alphabets are passed as inputs.

Uses of Depth Testing

The uses of depth testing are listed below −

  • It covers every functionality of the software at a depth.
  • It covers both automated and manual methods of testing.


This concludes our comprehensive take on the tutorial on Software Depth Testing. We’ve started with describing what is depth testing, practical example of depth testing, and uses of depth testing. This equips you with in-depth knowledge of Software Depth Testing. It is wise to keep practicing what you’ve learned and exploring others relevant to Software Testing to deepen your understanding and expand your horizons.
