ContainsConstraint Class

Definition

ContainsConstraint tests a whether a string contains a substring or a collection contains an object. It postpones the decision of which test to use until the type of the actual argument is known. This allows testing whether a string is contained in a collection or as a substring of another string using the same syntax.

Constructors

ContainsConstraint(Object)

Initializes a new instance of the ContainsConstraint class.

Fields

actual

The actual value being tested against a constraint

(Inherited from Constraint)

Properties

And

Returns a ConstraintExpression by appending And to the current constraint.

(Inherited from Constraint)
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.

(Inherited from Constraint)
IgnoreCase

Flag the constraint to ignore case and return self.

Or

Returns a ConstraintExpression by appending Or to the current constraint.

(Inherited from Constraint)
With

Returns a ConstraintExpression by appending And to the current constraint.

After(Int32) (Inherited from Constraint)
After(Int32, Int32) (Inherited from Constraint)
GetStringRepresentation() (Inherited from Constraint)
Matches(Object)

Test whether the constraint is satisfied by a given value

Matches<T>(ActualValueDelegate<T>) (Inherited from Constraint)
Matches<T>(T) (Inherited from Constraint)
ToString()

Default override of ToString returns the constraint DisplayName followed by any arguments within angle brackets.

Using<T>(Comparison<T>)
Using<T>(IComparer<T>)
Using<T>(IEqualityComparer<T>)
WriteActualValueTo(MessageWriter)

Write the actual value for a failing constraint test to a MessageWriter. The default implementation simply writes the raw value of actual, leaving it to the writer to perform any formatting.

(Inherited from Constraint)
WriteDescriptionTo(MessageWriter)

Write the constraint description to a MessageWriter

WriteMessageTo(MessageWriter)

Write the failure message to the MessageWriter provided as an argument. The default implementation simply passes the constraint and the actual value to the writer, which then displays the constraint description and the value. Constraints that need to provide additional details, such as where the error occured can override this.
