.NET Test
Bootstrap and refactor xUnit projects using the tested patterns from Codebelt xUnit and the matching application-host patterns from Codebelt Bootstrapper.
This skill has one job
The test host comes from Codebelt, not from Microsoft, and not from a builder you write in the test project.
Microsoft ships WebApplicationFactory<TEntryPoint>, and it only covers ASP.NET Core. Everything else — console apps, workers, hosted services — has no Microsoft equivalent, so teams hand-roll a HostBuilder in the test project and end up testing a composition root that no deployed process ever runs. Codebelt xUnit closes both gaps with one family of abstractions where the application's own entry point owns startup:
| What the test needs | Codebelt gives you | Instead of |
|---|---|---|
| One host per test / per narrow harness (web) | WebApplicationTestFactory.Create<TEntryPoint>(..., new ManagedWebApplicationFixture<TEntryPoint>()) |
new MyFactory() : WebApplicationFactory<Program> |
| One host shared by a test class (web) | WebApplicationTest<TEntryPoint, ManagedWebApplicationFixture<TEntryPoint>> |
IClassFixture<WebApplicationFactory<Program>> |
| One host per test / per narrow harness (console, worker) | ApplicationTestFactory.Create<TEntryPoint>(..., new ManagedApplicationFixture<TEntryPoint>()) |
a hand-built HostBuilder in the test project |
| One host shared by a test class (console, worker) | ApplicationTest<TEntryPoint, ManagedApplicationFixture<TEntryPoint>> |
a static host cached in a test helper |
That substitution is the deliverable. A run that leaves WebApplicationFactory in place, or that swaps the type while quietly rebuilding the host in test code, has not done the job no matter how green the test run looks.
