This library is used to define architecture rules as expectations that can be run and checked as part of the unit test execution.

Examples

• Test classes should have Tests as suffix:

  [Fact]
  public void ExpectTestClassesToBeSuffixedWithTests()
  {
    IRule rule = Expect.That.Types
        .Which(Have.Method.WithAttribute<FactAttribute>().OrAttribute<TheoryAttribute>())
        .ShouldMatchName("*Tests");
  
    rule.Check
        .InAllLoadedAssemblies()
        .ThrowIfViolated();
  }

• Methods that return Task should have Async as suffix:

  [Fact]
  public void AsyncMethodsShouldHaveAsyncSuffix()
  {
    IRule rule = Expect.That.Methods
      .WithReturnType<Task>().OrReturnType(typeof(Task<>))
      .ShouldMatchName("*Async")
      .AllowEmpty();
  
    rule.Check
      .InTestAssembly()
      .ThrowIfViolated();
  }
