I have a Ballerina package with multiple modules, and one of them consists mostly of autogenerated code for which I currently do not have tests.
When I generate test coverage report, the overall coverage percentage is heavily impacted by the absence of tests for that particular module. Is there a method or configuration to exclude this module from the overall test coverage calculations?
You can simply exclude generated sources from coverage as follows,
bal test --test-report --code-coverage --coverage-format=xml --excludes='./generated'
If you want to exclude a single Ballerina source file from coverage you can pass the file path with excludes flag. You can also use glob patterns to exclude different set of source files.
