How to write a Good Test Case in Software Testing

 

Software Testing in a crucial component of the Software Cycle, without this all processes can be termed futile. It fool-proofs all efforts to make sure the actual software product matches expected requirements and is free of all errors.

What is a Test Case?

In Software Testing, a test case is a set of actions, inputs, execution conditions and procedures to verify or check a particular feature or function of a product or application. It is important to write a good test case as they determine the competence of the feature/functionality.

A good test case has certain characteristics,

Characteristics of a Good Test Case

  1. Can be understood and executed by any tester

Your test case should seem to have a precise universal language which can easily be grasped by any tester. This makes sure that you have thoroughly studied and created an appropriate test for the required application

  • A good test case is created keeping in mind the end user

A good test case can only be created if the tester puts themselves in the shoes of the end user and includes all necessary details. You must be willing to put extra effort; this will help you in the long-run of your cases.

Remember: Your test determines the difference between a well-tested application and a poorly-tested application and will ultimately ensure how the end user receives it.

  • Small, isolated and atomic

This depends on what exactly requires the test but any good test case must be small, isolated and atomic. This makes them easier to understand and execute while making sure the errors are none or easily identifiable.

  • Independent of each other

Your test case should be independent of other cases and must fail/pass independently of each other. A good test must also define its expected result.

Now you know the basic characteristics of a good test case, remember these are not limited to the above points.
