ATC Test

Common tools for writing tests using XUnit, AutoFixture, NSubstitute and FluentAssertions.

Test Attributes

Name	Description
AutoNSubstituteData	Provides auto-generated data specimens generated by AutoFixture and NSubstitute as an extension to XUnit's [Theory] attribute.
InlineAutoNSubstituteData	Provides a data source for a data theory, with the data coming from inline values combined with auto-generated data specimens generated by AutoFixture and NSubstitute.
MemberAutoNSubstituteData	Provides a data source for a data theory, with the data coming from one of the following sources and combined with auto-generated data specimens generated by AutoFixture and NSubstitute.

Note: NSubstitute is used when the type being created is abstract, or when the [Substitute] is applied.

Test Helpers

Name	Description
EquivalencyAssertionOptionsExtensions	Extensions for FluentAssertions to compare dates with a precision when using .BeEquivalentTo().
FixtureFactory	Static factory for creating AutoFixture Fixture instances.
ObjectExtensions	Extensions calling protected members on an object.
SubstituteExtensions	Extensions for NSubstitutes to wait for calls and get arguments of a received call.
TaskExtensions	Extensions for Tasks to add timeouts when awaiting.

Extensibility

The default Fixture returned by the FixtrueFactory.Create() method is used for all the Attributes mentioned above.

To add customizations to this, you can add the AutoRegisterAttribute to any custom ICustomization or ISpecimenBuilder to have it automatically added to the Fixture.

See CancellationTokenGenerator for an example on how to do this.
