14 Tips & Best Practices in Writing Test 
Cases 
 

As a software tester, you know how crucial well-written test cases are in ensuring that
the software behaves as intended. Not only do they help detect bugs early on, but 
they also contribute to a faster and more efficient software development cycle. 

To help you in this regard, I've compiled a set of best practices and tips for writing 
test cases that are thorough, easy to understand, and efficient. By following these 
guidelines, you can rest assured that your test cases are up to par and contributing to 
a successful software release. 

1. Understand the Requirements
 

  • Before writing test cases, take some time to really understand the requirements 
    and specifications of the software you're testing.
  • Having a clear understanding of the requirements will help you write test cases 
    that cover all possible scenarios, ensuring thorough testing and better software 
    quality. 

Give a read to tips in Requirement Analysis in QA here in detail. 

2. Use a Standard Template
 

  • Using a standard template for writing test cases can make your life a whole lot 
    easier. 
  • A typical template includes fields for Test Case ID, Description, Steps to 
    Reproduce, Expected Result, Actual Result, and Status. 
  • It makes your test cases easier to read, understand, and manage, saving you time
    and effort in the long run. 

So, here's little wisdom - why not make your life even easier by using test case management tools like Crosscheck

Crosscheck provides standard templates for test cases. Its test case form has four simple steps: test objective, preconditions, test steps, and expected results. It's super intuitive and will save you a ton of time and hassle.

3. Be Specific and Clear
 

  • When writing test case steps, be as clear and specific as possible. 
  • Avoid ambiguity in your test case descriptions to ensure that testers can execute 
    them accurately and effectively.

4. Cover Positive and Negative Scenarios
 

  • Don't forget to test both positive and negative scenarios. 
  • Positive scenarios help verify that the system behaves as expected, while negative 
    scenarios help identify how the system handles unexpected inputs or errors. 

5. Keep Test Cases Atomic
 

  • Keep your test cases small and atomic, focusing on testing one specific 
    functionality at a time. 
  • This approach makes it easier to identify the cause of failures and simplifies test 
    case maintenance in the long run. 

6. Prioritize Test Cases: 
 

  • Prioritize your test cases based on factors like risk, criticality, and frequency of 
    use. 
  • Start by focusing on high-priority test cases to ensure that the most critical 
    functionalities are thoroughly tested. 

Now, here's where Crosscheck comes in to make your life even easier: 

Crosscheck doesn't just stop at providing you with a platform to manage your test cases. It goes the extra mile by offering weightage to each test case. This makes it super simple for you to prioritize your test cases effectively, ensuring that you're focusing your testing efforts where they matter most.

7. Reuse Test Cases: 
 

  • Identify reusable test cases and create a test case repository. Reusing test cases 
    saves time and ensures consistency across different test cycles. 

Crosscheck have a centralized repository for all your test cases. This ensures easy 
access and organization, allowing you to group them by project, milestone, feature, 
or any other relevant criteria. 

Additionally, intuitive search and filter options help you quickly locate specific test 
cases when needed. This ensures your testing efforts remain organized and tightly 
aligned with your project requirements.

8. Review and Refine: 
 

  • Review test cases for completeness, accuracy, and clarity. 
  • Refine test cases based on feedback from stakeholders and previous test 
    executions. 

9. Automate Where Possible: 
 

  • Automate repetitive test cases to save time and effort. 
  • Automated test cases can be run quickly and repeatedly, allowing for faster 
    feedback and regression testing.

10. Document Assumptions and Risks: 
 

  • Document any assumptions made while writing test cases. 
  • Identify and document any risks associated with the test cases. 

11. Maintain Bug Traceability: 
 

  • Ensure that there is traceability between test cases, requirements, and defects. 
    Traceability helps in understanding the coverage of test cases and ensures that 
    all requirements are tested. 

How Crosscheck Offers Traceability: 
 

Bug Reporting and Test Case Association: 
 

When a test case fails, Crosscheck enables you to report bugs directly within the 
platform. These reported bugs are automatically linked to the corresponding test 
case, providing clear traceability between test failures and reported issues.

Test Run Execution and Bug Association: 
 

By establishing this connection, you can trace back from bugs to the specific test runs 
and test cases that identified them, ensuring complete traceability throughout your 
testing process.

12. Test for Performance and Security: 
 

  • Include test cases to verify the performance and security aspects of the software. 
  • Performance testing ensures that the software meets performance requirements, 
    while security testing identifies vulnerabilities and weaknesses. 

13. Update Test Cases Regularly: 
 

  • Test cases should be updated regularly to reflect changes in the software. 
  • Keep test cases up to date to ensure that they remain relevant and effective. 

Crosscheck updates all your test case repository update in real time in QA Dashboard. Its consolidated view empowers you to be a more proactive and impactful QA tester and efficient in bug identification and reporting activities.
