Test Plans
It is important to make sure that tests are planned carefully to make sure that as many bugs as possible are fixed before deployment.
Test data
- To make sure that testing is thorough, both expected and unexpected data should be used in testing:
- Valid data is correct and of the right format.
- Extreme data is correct but on the edge of the valid range.
- Invalid data is not within the acceptable range or is an invalid format.
- Null data is where no data is entered to see what happens.
- Erroneous data is of the wrong type altogether.
Test plans
- Test plans make sure that testing is effective by detailing exactly which tests will be performed, what test data will be used, and what the system's intended outcome should be.
- A test plan should be created before development. It is part of the design stage.
- Testing should cover all of the success criteria of the project.
