      I have an ASP.NET Core MVC application under ContosoUniversity/ — a university
      enrollment system with multiple controllers, EF Core data access, and a
      notification service. This is a project-wide, multi-file test generation task.

      Please scaffold a new test project, then write comprehensive unit tests
      across the controllers (Students, Courses, Departments, Instructors), the
      services, and the data layer. Achieve high code coverage. The generated
      tests should compile and pass, and the test project should be configured so
      `dotnet test --collect:"XPlat Code Coverage"` produces a Cobertura XML
      report under TestResults/ (add `coverlet.collector` to the test csproj if
      it is not already there).

      AsyncTaxRateProvider), shipping calculators (FreeShippingCalculator,
      FlatShippingCalculator with free-over threshold, and
      WeightBasedShippingCalculator with WeightBracket boundaries), and
      async PriceFetcher / InventoryChecker seams plus an InventoryError
      type used by checkout() (see its README.md for the layout). There

      generation task across the cart, pricing, tax, shipping, and
      inventory modules.

      Please scaffold a comprehensive Vitest test suite under
