Best Practice for Writing Test Case

There are certain practices that one could follow while writing the test cases that would be considered beneficial. 

  1. 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. 
  2. 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. 
  3. Zero Assumptions: Test cases should not contain assumed data, and don’t come up with features/modules that don’t exist. 
  4. Traceability: Test cases should be traceable for future reference, so while writing it’s important to keep that in mind, 
  5. Different input data: While writing test cases, all types of data must be taken into consideration. 
  6. Strong module name: The module name should be self-explanatory while writing the test case.  
  7. 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. 
  8. Maximum conditions: All kinds of conditions should be taken into consideration while writing a test, increasing the effectiveness. 
  9. Meeting requirements: While writing the test case the client/customer/end-user requirements must be met.
  10. Repetitive Results: The test case must be written in such a way that it should provide the same result. 
  11. 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. 
  12. 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.
  13. 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.
  14. Add proper preconditions and postconditions: Preconditions and postconditions for the test cases must be mentioned properly and clearly.
  15. 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.
  16. Specify the exact expected outcome: Include the exact expected result, which tells us what will be result of a particular test step.

How to write Test Cases – Software Testing

Software testing is known as a process for validating and verifying the working of a software/application. It makes sure that the software is working without any errors, bugs, or any other issues and gives the expected output to the user. The software testing process isn’t limited to finding faults in the present software but also finding measures to upgrade the software in various factors such as efficiency, usability, and accuracy. So, to test software the software testing provides a particular format called a Test Case

This article focuses on discussing the following topics in the Test Case:

What is a Test Case?

A test case is a defined format for software testing required to check if a particular application/software is working or not. A test case consists of a certain set of conditions that need to be checked to test an application or software i.e. in more simple terms when conditions are checked it checks if the resultant output meets with the expected output or not. A test case consists of various parameters such as ID, condition, steps, input, expected result, result, status, and remarks....

Test Case Management Tools

Test management tools help to manage the test cases. These tools are automated tools that decrease the time and effort of a tester as compared to the traditional way. Some test case management tools include advanced dashboards, easier bug, and progress tracking as well as management, custom test case templates, integration of test cases, inviting guest testers, managing team requirements and plans, and much more....

Types of Test Cases

Functionality Test Case: The functionality test case is to determine if the interface of the software works smoothly with the rest of the system and its users or not. Black box testing is used while checking for this test case, as we check everything externally and not internally for this test case.  Unit Test Case: In unit test case is where the individual part or a single unit of the software is tested. Here each unit/ individual part is tested, and we create a different test case for each unit.   User Interface Test Case: The UI test or user interface test is when every component of the UI that the user would come in contact with is tested. It is to test if the UI components requirement made by the user are fulfilled or not.   Integration Test Case: Integration testing is when all the units of the software are combined and then they are tested. It is to check that each component and its units work together without any issues.  Performance Test Case: The performance test case helps to determine response time as well as the overall effectiveness of the system/software. It’s to see if the application will handle real-world expectations.  Database Test Case: Also known as back-end testing or data testing checks that everything works fine concerning the database. Testing cases for tables, schema, triggers, etc. are done.  Security Test Case: The security test case helps to determine that the application restricts actions as well as permissions wherever necessary. Encryption and authentication are considered as main objectives of the security test case. The security test case is done to protect and safeguard the data of the software.  Usability Test Case: Also known as a user experience test case, it checks how user-friendly or easy to approach a software would be. Usability test cases are designed by the User experience team and performed by the testing team.  User Acceptance Test Case: The user acceptance case is prepared by the testing team but the user/client does the testing and review if they work in the real-world environment....
