unit-testing

How to write, run and report unit and integration tests in this repository: the test conventions for .NET (xUnit) and Angular (Vitest), the RED-first workflow, the rule that every resource a test run creates is removed afterwards whether the run passes or fails, and the format of the detailed result report. Use when: writing or running tests, the senior-test-engineer agent starts work, or the user says /unit-testing, 'run the tests', 'write the unit tests', or 'clean up after the tests'.
