.NET Testing Best Practices
summary
Adds unit tests to an ASP.NET Core sample using xUnit, Moq (with auto-mocking) and FluentAssertions, refactors a static singleton into constructor-injected ILightSwitcher and extracts ITimePeriodHelper so tests can control time-of-day. Implements parameterized theories, debugs failing cases, fixes a bug caused by string time names by introducing a TimePeriod enum, gets 13 passing tests locally, and emits JUnit XML from dotnet test for GitHub Actions test reporting.
