Quality Assurance Best practices

1. Learn to analyze your test results thoroughly. Do not ignore the test result. The final test result may be ‘pass’ or ‘fail’ but troubleshooting the root cause of ‘fail’ will lead you to the solution of the problem. Testers will be respected if they not only log the bugs but also provide solutions.

2. Learn to maximize the test coverage every time you test any application. Though 100 percent test coverage might not be possible you can always try to reach it.

3. To ensure maximum test coverage break your application into smaller functional modules. Write test cases on individual unit modules. Also, if possible, break these modules into smaller parts, e.g.: If you have divided your website application in modules and “accepting user information” is one of the modules. You can break this “user information” screen into smaller parts for writing test cases: Parts like UI testing, security testing, functional testing of the user information form etc. Apply all form field type and size tests, negative and validation tests on input fields and write all test cases for maximum coverage.

4. While writing test cases, write test cases for the intended functionality first i.e: for valid conditions according to requirements. Then write test cases for invalid conditions. This will cover expected as well unexpected behavior of the application.

5. Think positive. Start testing the application by intending to find bugs/errors. Don’t think beforehand that there will not be any bugs in the application. If you test the application with the intention of finding bugs you will definitely succeed.

6. Write your test cases in requirement analysis and the design phase itself. This way you can ensure all the requirements are testable.

7. Make your test cases available to developers prior to coding. Don’t keep your test cases with you waiting to get the final application release for testing, thinking that you can log more bugs. Let developers analyze your test cases thoroughly to develop a quality application. This will also save the re-work time.

8. If possible identify and group your test cases for regression testing. This will ensure quick and effective manual regression testing.

9. Applications requiring critical response time should be thoroughly tested for performance. Performance testing is the critical part of many applications. In manual testing this is mostly ignored by testers. Find out ways to test your application for performance. If it is not possible to create test data manually, then write some basic scripts to create test data for performance testing or ask the developers to write it for you.

10. Programmers should not test their own code. Basic unit testing of the developed application should be enough for developers to release the application for the testers. But testers should not force developers to release the product for testing. Let them take their own time. Everyone from lead to manger will know when the module/update is released for testing and they can estimate the testing time accordingly. This is a typical situation in an agile project environment

Bonus tip:
11.Go beyond requirement testing. Test the application for what it is not supposed to do.
