Each PostgreSQL database has a server encoding. Negative testing is the process of applying as much creativity as possible and validating the application against invalid data. There is only the Create operation. Haphazard, trial-and-error testing will not suffice. Equivalence classes of valid values: In total, 4 equivalence classes are obtained.

Invalid/Negative Test Data: This is data that the program rejects as invalid because the data type is incorrect. To provide protection, test data that needs to be designed should cover the following topics: Quality assurance testers test the applications from a user's perspective, not from an internal perspective. The code should identify that this data is invalid and handle it accordingly. Test data should be created before test cases execution to save time and meet deadline.

And there's some truth to that: If you are writing and executing too many negative tests, the release cycle of the application might be affected, and your releases could get delayed. As long as you consistently set the client encoding to the wrong value, the data will appear to be correct: When diagnosing encoding problems, it is very helpful to know what data the database actually stores. While executing test cases, he needs some data to input in order to get the expected output. Negative and positive testing are equally important, sotake advantage of both to ensure that yourapplications arereliable and stable. Or in the case of trying to add strings in a calculator, an error will be emitted, and no calculation will take place. Test Case Review Process Tips and Tricks!
