Syntax

public class CollectionSubsetConstraint : CollectionItemsEqualConstraint, IConstraint, IResolveConstraint

Constructors

CollectionSubsetConstraint(IEnumerable)

Construct a CollectionSubsetConstraint

Declaration

public CollectionSubsetConstraint(IEnumerable expected)

Parameters

Type	Name	Description
IEnumerable	expected	The collection that the actual value is expected to be a subset of

Properties

Description

The Description of what this constraint tests, for use in messages and in the ConstraintResult.

Declaration

public override string Description { get; }

Property Value

Type	Description
string

Overrides

Constraint.Description

DisplayName

The display name of this Constraint for use by ToString(). The default value is the name of the constraint with trailing "Constraint" removed. Derived classes may set this to another name in their constructors.

Declaration

public override string DisplayName { get; }

Property Value

Type	Description
string

Overrides

Constraint.DisplayName

Methods

ApplyTo<TActual>(TActual)

Test whether the constraint is satisfied by a given value.

Declaration

public override ConstraintResult ApplyTo<TActual>(TActual actual)

Parameters

Type	Name	Description
TActual	actual

Returns

Type	Description
ConstraintResult

Type Parameters

Name	Description
TActual

Overrides

CollectionConstraint.ApplyTo<TActual>(TActual)

Matches(IEnumerable)

Test whether the actual collection is a subset of the expected collection provided.

Declaration

protected override bool Matches(IEnumerable actual)

Parameters

Type	Name	Description
IEnumerable	actual

Returns

Type	Description
bool

Overrides

CollectionConstraint.Matches(IEnumerable)

Using<TSubsetElement, TSupersetElement>(Func<TSubsetElement, TSupersetElement, bool>)

Flag the constraint to use the supplied predicate function

Declaration

public CollectionSubsetConstraint Using<TSubsetElement, TSupersetElement>(Func<TSubsetElement, TSupersetElement, bool> comparison)

Parameters

Type	Name	Description
Func<TSubsetElement, TSupersetElement, bool>	comparison	The comparison function to use.

Returns

Type	Description
CollectionSubsetConstraint	Self.

Type Parameters

Name	Description
TSubsetElement	The type of the elements in the actual subset.
TSupersetElement	The type of the elements in the expected superset.
