Documentation

public static FileOrDirectoryExistsConstraint Exist { get; }

public static ConstraintExpression Not { get; }

Returns a ConstraintExpression that negates any following constraint.

protected Does()

public static SomeItemsConstraint Contain(object expected)

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

public static ContainsConstraint Contain(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 static DictionaryContainsKeyConstraint ContainKey(object expected)

Returns a new DictionaryContainsKeyConstraint checking for the presence of a particular key in the Dictionary key collection.

public static DictionaryContainsValueConstraint ContainValue(object expected)

Returns a new DictionaryContainsValueConstraint checking for the presence of a particular value in the Dictionary value collection.

public static EndsWithConstraint EndWith(string expected)

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

public static RegexConstraint Match(string pattern)

Returns a constraint that succeeds if the actual value matches the regular expression supplied as an argument.

public static RegexConstraint Match(Regex regex)

Returns a constraint that succeeds if the actual value matches the regular expression supplied as an argument.

public static StartsWithConstraint StartWith(string expected)

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