I hope the Unit Testing Module API will give you more information about success tests like JUnit results.
I use Jenkins to run tests and check test results.
In order to check the result on the Jenkins screen, the return value of unittests / status is converted to JUnit result.xml.
Currently, unittests / status only returns information about failed tests, little information about successful tests.
I get only the number of successful tests by subtracting the number of failed tests from the total number of tests.
It would be nice to have the ability to get information about all the tests, including detailed information about the success test (test name, message, etc.).
