Class FrozenAttribute

Namespace: AutoFixture.Xunit
Assembly: AutoFixture.Xunit.dll

An attribute that can be applied to parameters in an AutoDataAttribute-driven Theory to indicate that the parameter value should be frozen so that the same instance is returned every time the IFixture creates an instance of that type.

Constructors

FrozenAttribute()

Initializes a new instance of the FrozenAttribute class.

public FrozenAttribute()

Remarks

The Matching criteria used to determine which requests will be satisfied by the frozen parameter value is ExactType.

FrozenAttribute(Matching)

Initializes a new instance of the FrozenAttribute class.

public FrozenAttribute(Matching by)

Parameters

by Matching

The Matching criteria used to determine which requests will be satisfied by the frozen parameter value.

Properties

As

Gets or sets the Type that the frozen parameter value should be mapped to in the IFixture.

[Obsolete("The ability to map a frozen object to a specific type is deprecated and will likely be removed in the future. If you wish to map a frozen type to its implemented interfaces, use [Frozen(Matching.ImplementedInterfaces)]. If you instead wish to map it to its direct base type, use [Frozen(Matching.DirectBaseType)].", true)]
public Type As { get; set; }

Parameters
