What is a test case in software testing?

A test case comprises different steps, inputs, and expected results that help QA to verify whether a specific feature works correctly in an application. This is a great help for your testers as they can check system behavior under different conditions, including both valid and invalid scenarios.

What makes a good test case?

If you want to make good test cases, make them clear, simple, and focus on one objective. More than that, it should also explain different steps, expected results, valid test data and be easy for anyone to understand and execute.

How to write effective test cases?

Always ensure the test cases focus on clarity, coverage, and the real user behavior. Use simple steps, mention the results you are expecting, and avoid unnecessary complexity while designing. An approach like this can improve the quality of test case QA and provide better results.

What are the common mistakes in test case design techniques?

The common mistakes we usually find are writing unclear steps, missing edge cases and boundary values, creating many test cases that waste time and ignoring negative test case examples. Avoiding these mistakes can affect the quality of your software.

Can you give me an example of a test case?

Let's look at a simple QA test case example, but in the real test cases, you can see more details, such as test data, prerequisites, and results. Test Case ID: TC_01 Scenario: Verify email input Steps: Enter a valid email → Submit Expected Result: Email is accepted
