Methods

In<T>(ICollection<T>)

Creates a parameter capture that will store values in a collection.

public static T In<T>(ICollection<T> collection)

Parameters

collection ICollection<T>

Assert code:

Assert.Equal("Hello!", parameters.Single());

In<T>(IList<T>, Expression<Func<T, bool>>)

Creates a parameter capture that will store specific values in a collection.

public static T In<T>(IList<T> collection, Expression<Func<T, bool>> predicate)

Parameters

collection IList<T>

The collection that will store captured parameter values

predicate Expression<Func<T, bool>>

A predicate used to filter captured parameters

Returns

T

Type Parameters

T

The captured object type

Examples

Arrange code:

var parameters = new List{string}();
mock.Setup(x => x.DoSomething(Capture.In(parameters, p => p.StartsWith("W"))));

Assert code:

Assert.Equal("Hello!", parameters.Single());

With<T>(CaptureMatch<T>)

Creates a parameter capture using specified CaptureMatch<T>.

public static T With<T>(CaptureMatch<T> match)

Parameters

match CaptureMatch<T>

Returns

T

Type Parameters

T

The captured object type

Examples

Arrange code:

var capturedValue = string.Empty;
var match = new CaptureMatch{string}(x => capturedValue = x);
mock.Setup(x => x.DoSomething(Capture.With(match)));

Assert code:

Assert.Equal("Hello!", capturedValue);
