EqualConstraint Class

EqualConstraint is able to compare an actual value with the expected value provided in its constructor. Two objects are considered equal if both are null, or if both have the same value. NUnit has special semantics for some object types.

Constructors
| EqualConstraint(Object) |
Initializes a new instance of the EqualConstraint 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) |
| AsCollection |
Flag the constraint to compare arrays as collections and return self. |
| Days |
Causes the tolerance to be interpreted as a TimeSpan in days. |
| 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) |
| Hours |
Causes the tolerance to be interpreted as a TimeSpan in hours. |
| IgnoreCase |
Flag the constraint to ignore case and return self. |
| Milliseconds |
Causes the tolerance to be interpreted as a TimeSpan in milliseconds. |
| Minutes |
Causes the tolerance to be interpreted as a TimeSpan in minutes. |
| NoClip |
Flag the constraint to suppress string clipping and return self. |
| Or |
Returns a ConstraintExpression by appending Or to the current constraint. (Inherited from Constraint) |
| Percent |
Switches the .Within() modifier to interpret its tolerance as a percentage that the actual values is allowed to deviate from the expected value. |
| Seconds |
Causes the tolerance to be interpreted as a TimeSpan in seconds. |
| Ticks |
Causes the tolerance to be interpreted as a TimeSpan in clock ticks. |
| Ulps |
Switches the .Within() modifier to interpret its tolerance as a distance in representable values (see remarks). |
| With |
Returns a ConstraintExpression by appending And to the current constraint. (Inherited from Constraint) |
Methods
| 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. (Inherited from Constraint) |
| Using(IComparer) |
Flag the constraint to use the supplied IComparer object. |
| Using(IEqualityComparer) |
Flag the constraint to use the supplied IEqualityComparer object. |
| Using<T>(Comparison<T>) |
Flag the constraint to use the supplied Comparison object. |
| Using<T>(IComparer<T>) |
Flag the constraint to use the supplied IComparer object. |
| Using<T>(IEqualityComparer<T>) |
Flag the constraint to use the supplied IEqualityComparer object. |
| Within(Object) |
Flag the constraint to use a tolerance when determining equality. |
| 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 description of this constraint |
| WriteMessageTo(MessageWriter) |
Write a failure message. Overridden to provide custom failure messages for EqualConstraint. |
Explicit Interface Implementations
