PHPUnit_Framework_Constraint_IsIdentical
extends PHPUnit_Framework_Constraint
in package
Constraint that asserts that one value is identical to another.
Identical check is performed with PHP's === operator, the operator is explained in detail at http://www.php.net/manual/en/types.comparisons.php. Two values are identical if they have the same value and are of the same type.
The expected value is passed in the constructor.

Return values
int —evaluate()
Evaluates the constraint for parameter $other
public
evaluate(mixed $other[, string $description = '' ][, bool $returnResult = false ]) : mixed
If $returnResult is set to false (the default), an exception is thrown in case of a failure. null is returned otherwise.
If $returnResult is true, the result of the evaluation is returned as a boolean value instead: true in case of success, false in case of a failure.
Parameters
- $other : mixed
-
Value or object to evaluate.
- $description : string = ''
-
Additional information about the test
- $returnResult : bool = false
-
Whether to return a result or throw an exception
Tags
Return values
mixed —toString()
Returns a string representation of the constraint.
public
toString() : string
Return values
string —additionalFailureDescription()
Return additional failure description where needed
protected
additionalFailureDescription(mixed $other) : string
The function can be overridden to provide additional failure information like a diff
Parameters
- $other : mixed
-
Evaluated value or object.
Return values
string —fail()
Throws an exception for the given compared value and test description
protected
fail(mixed $other, string $description[, ComparisonFailure $comparisonFailure = null ]) : mixed
Parameters
- $other : mixed
-
Evaluated value or object.
- $description : string
-
Additional information about the test
- $comparisonFailure : ComparisonFailure = null

Return values
mixed —failureDescription()
Returns the description of the failure
protected
failureDescription(mixed $other) : string
The beginning of failure messages is "Failed asserting that" in most cases. This method should return the second part of that sentence.
Parameters
- $other : mixed
-
Evaluated value or object.
Return values
string —matches()
Evaluates the constraint for parameter $other. Returns true if the constraint is met, false otherwise.
protected
matches(mixed $other) : bool
This method can be overridden to implement the evaluation algorithm.
Parameters
- $other : mixed
-
Value or object to evaluate.
