How do I get unit test coverage in SonarQube?

The coverage report has to be computed by an external tool first and then SonarQube will be provided with informations coming from this report during the analysis. To get coverage informations in SonarQube, we provide the generic test data format for the coverage and the tests reports.

Why is a.description not covered in a unit test?

After running unit tests, if the line starting with a.Description is not covered, it’s an indication that the loop never begins iterating because the query returns no records. This is a failure of the test data setup: records weren’t created that would exercise the functionality of this specific code path.

How to do the apex unit testing challenge?

The unit tests must be in a separate test class called ‘TestVerifyDate’. The unit tests must cover scenarios for all lines of code included in the Apex class, resulting in 100% code coverage. Run your test class at least once (via ‘Run All’ tests the Developer Console) before attempting to verify this challenge.

Why are unit tests so difficult to use?

In branching code, you won’t be able to ensure that diverging logical paths all execute in a single unit test. Trying to test too much in a single test method tends to make unit tests more difficult to understand and more fragile.
