public ConstraintExpression None { get; }

Returns a ConstraintExpression, which will apply the following constraint to all members of a collection, succeeding if all of them fail.

public TrueConstraint True { get; }

Returns a constraint that tests for True

public UniqueItemsConstraint Unique { get; }

public XmlSerializableConstraint XmlSerializable { get; }

Returns a constraint that tests whether an object graph is serializable in xml format.

public ConstraintFactory()

public static ConstraintExpression Exactly(int expectedCount)

Returns a ConstraintExpression, which will apply the following constraint to all members of a collection, succeeding only if a specified number of them succeed.

public AssignableFromConstraint AssignableFrom(Type expectedType)

Returns a constraint that tests whether the actual value is assignable from the type supplied as an argument.

public AssignableFromConstraint AssignableFrom<T>()

Returns a constraint that tests whether the actual value is assignable from the type supplied as an argument.

public AssignableToConstraint AssignableTo(Type expectedType)

Returns a constraint that tests whether the actual value is assignable from the type supplied as an argument.

public AssignableToConstraint AssignableTo<T>()

Returns a constraint that tests whether the actual value is assignable from the type supplied as an argument.

public GreaterThanOrEqualConstraint AtLeast(object expected)

Returns a constraint that tests whether the actual value is greater than or equal to the suppled argument

public LessThanOrEqualConstraint AtMost(object expected)

Returns a constraint that tests whether the actual value is less than or equal to the suppled argument

public ResolvableConstraintExpression Attribute(Type expectedType)

Returns a new AttributeConstraint checking for the presence of a particular attribute on an object.

public ResolvableConstraintExpression Attribute<T>()

Returns a new AttributeConstraint checking for the presence of a particular attribute on an object.

public CollectionContainsConstraint Contains(object expected)

Returns a new CollectionContainsConstraint checking for the presence of a particular object in the collection.

public ContainsConstraint Contains(string expected)

Returns a new ContainsConstraint. This constraint will, in turn, make use of the appropriate second-level constraint, depending on the type of the actual argument. This overload is only used if the item sought is a string, since any other type implies that we are looking for a collection member.

public SubstringConstraint ContainsSubstring(string expected)

Returns a constraint that succeeds if the actual value contains the substring supplied as an argument.

public SubstringConstraint DoesNotContain(string expected)

Returns a constraint that fails if the actual value contains the substring supplied as an argument.

public EndsWithConstraint DoesNotEndWith(string expected)

Returns a constraint that fails if the actual value ends with the substring supplied as an argument.

public RegexConstraint DoesNotMatch(string pattern)

Returns a constraint that fails if the actual value matches the pattern supplied as an argument.

public StartsWithConstraint DoesNotStartWith(string expected)

Returns a constraint that fails if the actual value starts with the substring supplied as an argument.

public EndsWithConstraint EndsWith(string expected)

Returns a constraint that succeeds if the actual value ends with the substring supplied as an argument.

public EqualConstraint EqualTo(object expected)

Returns a constraint that tests two items for equality

public CollectionEquivalentConstraint EquivalentTo(IEnumerable expected)

Returns a constraint that tests whether the actual value is a collection containing the same elements as the collection supplied as an argument.

public GreaterThanConstraint GreaterThan(object expected)

Returns a constraint that tests whether the actual value is greater than the suppled argument

public GreaterThanOrEqualConstraint GreaterThanOrEqualTo(object expected)

Returns a constraint that tests whether the actual value is greater than or equal to the suppled argument

public RangeConstraint<T> InRange<T>(T from, T to) where T : IComparable<T>

Returns a constraint that tests whether the actual value falls within a specified range.

public InstanceOfTypeConstraint InstanceOf(Type expectedType)

Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type.

public InstanceOfTypeConstraint InstanceOf<T>()

Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type.

public InstanceOfTypeConstraint InstanceOfType(Type expectedType)

Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type.

public InstanceOfTypeConstraint InstanceOfType<T>()

Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type.

public LessThanConstraint LessThan(object expected)

Returns a constraint that tests whether the actual value is less than the suppled argument

public LessThanOrEqualConstraint LessThanOrEqualTo(object expected)

Returns a constraint that tests whether the actual value is less than or equal to the suppled argument

public RegexConstraint Matches(string pattern)

Returns a constraint that succeeds if the actual value matches the Regex pattern supplied as an argument.

public CollectionContainsConstraint Member(object expected)

Returns a new CollectionContainsConstraint checking for the presence of a particular object in the collection.

public ResolvableConstraintExpression Property(string name)

Returns a new PropertyConstraintExpression, which will either test for the existence of the named property on the object being tested or apply any following constraint to that property.

public SamePathConstraint SamePath(string expected)

Returns a constraint that tests whether the path provided is the same as an expected path after canonicalization.

public SamePathOrUnderConstraint SamePathOrUnder(string expected)

Returns a constraint that tests whether the path provided is the same path or under an expected path after canonicalization.

public StartsWithConstraint StartsWith(string expected)

Returns a constraint that succeeds if the actual value starts with the substring supplied as an argument.

public SubstringConstraint StringContaining(string expected)

Returns a constraint that succeeds if the actual value contains the substring supplied as an argument.

public EndsWithConstraint StringEnding(string expected)

Returns a constraint that succeeds if the actual value ends with the substring supplied as an argument.

public RegexConstraint StringMatching(string pattern)

Returns a constraint that succeeds if the actual value matches the Regex pattern supplied as an argument.

public StartsWithConstraint StringStarting(string expected)

Returns a constraint that succeeds if the actual value starts with the substring supplied as an argument.

public SubPathConstraint SubPath(string expected)

Returns a constraint that tests whether the path provided is the same path or under an expected path after canonicalization.

public CollectionSubsetConstraint SubsetOf(IEnumerable expected)

Returns a constraint that tests whether the actual value is a subset of the collection supplied as an argument.

public ExactTypeConstraint TypeOf(Type expectedType)

Returns a constraint that tests whether the actual value is of the exact type supplied as an argument.
