Final answer:
When creating Apex unit tests, it is important to test all scenarios, use test data, aim for high code coverage, isolate tests, and use assertions.
Step-by-step explanation:
When creating Apex unit tests, there are several best practices that can be followed:
- Test All Scenarios: Make sure to test all possible scenarios, including positive and negative test cases, boundary cases, and any edge cases.
- Use Test Data: Use test data to simulate different scenarios and ensure that the code behaves as expected.
- Coverage: Aim to achieve as close to 100% code coverage as possible to ensure that all lines of code are being tested.
- Isolation: Write tests that are isolated from each other, meaning they do not depend on each other's execution.
- Assertions: Use assertions to validate the expected results of the test.
By following these best practices, you can ensure that your Apex unit tests are comprehensive and reliable.
