aweXpect.Reflection Nuget

Expectations for reflection types.

Overview​

This library contains expectations on reflection types:

You can apply the expectations either on a single type or a collection of types (e.g. Assembly[] or IEnumerable<Type?>).

In​

There is also a helper construct (In) to simplify the construction of collections of reflection types that match specific criteria:

// Verifies that all xunit test classes (types with at least one method with a `FactAttribute` or `TheoryAttribute`) are sealed:
var xunitTestClasses = In.AllLoadedAssemblies().Types().Methods().With<FactAttribute>().OrWith<TheoryAttribute>().Types();
await That(xunitTestClasses).AreSealed();

This helper consists of the static class In for accessing assemblies and allows filtering and navigating between the reflection types. The helper types are themselves a collection, so the collection expectations can be applied to them.

Assemblies​

Name​

You can verify the name of an assembly or a collection of assemblies:

Assembly subject = Assembly.GetEntryAssembly();
Assembly[] subjects = AppDomain.CurrentDomain.GetAssemblies();

await Expect.That(subject).HasName("aweXpect.Reflection");
await Expect.That(subjects).HaveName("aweXpect").AsPrefix();

You can use the same configuration options as when comparing strings.

Types​

Name / Namespace​

You can verify the name or namespace of a type or a collection of types:

Type subject = typeof(MyClass);
IEnumerable<Type> subjects = In.EntryAssembly().Types();

await Expect.That(subject).HasNamespace("aweXpect").AsPrefix();
await Expect.That(subject).HasName("MyClass");

await Expect.That(subject).HaveNamespace("aweXpect").AsPrefix();
await Expect.That(subjects).HaveName("Tests").AsSuffix();

You can use the same configuration options as when comparing strings.
