There are certain practices that one could follow while writing the test cases that would be considered beneficial.
- Simple and clear: Test cases need to be very concise, clear, and transparent. They should be easy and simple to understand not only for oneself but for others as well.
- Maintaining the client/customer/end-user requirements must be unique: While writing the test cases, it’s necessary to make sure that they aren’t being written over and over again and that each case is different from the others.
- Zero Assumptions: Test cases should not contain assumed data, and don’t come up with features/modules that don’t exist.
- Traceability: Test cases should be traceable for future reference, so while writing it’s important to keep that in mind,
- Different input data: While writing test cases, all types of data must be taken into consideration.
- Strong module name: The module name should be self-explanatory while writing the test case.
- Minimal Description: The description of a test case should be small, one or two lines are normally considered good practice, but it should give the basic overview properly.
- Maximum conditions: All kinds of conditions should be taken into consideration while writing a test, increasing the effectiveness.
- Meeting requirements: While writing the test case the client/customer/end-user requirements must be met.
- Repetitive Results: The test case must be written in such a way that it should provide the same result.
- Different Techniques: Sometimes testing all conditions might not be possible but using different testing with different test cases could help to check every aspect of a software.
- Create test cases with the end user’s perspective: Create test cases by keeping end-user in mind and the test cases must meet customer requirements.
- Use unique Test Case ID: It is considered a good practice to use a unique Test Case ID for the test cases following a naming convention for better understanding.
- Add proper preconditions and postconditions: Preconditions and postconditions for the test cases must be mentioned properly and clearly.
- Test cases should be reusable: There are times when the developer updates the code, then the testers need to update the test cases to meet the changing requirements.
- Specify the exact expected outcome: Include the exact expected result, which tells us what will be result of a particular test step.
