+/// Builds the options every test context uses.

+/// Each test asks for its own InMemory database, so each one needs its own
+/// <see cref="DbContextOptions{TContext}"/> and EF builds a separate internal service
+/// provider for it. Past twenty of those EF raises
+/// <see cref="CoreEventId.ManyServiceProvidersCreatedWarning"/> as an exception, which
+/// fails whichever tests happen to run after the twentieth provider rather than the test
+/// that built it. That count is a property of how the harness allocates contexts, not of
+/// the behaviour under test, so the warning is ignored once here instead of per test.
