Detailed Description

Abstract base class for constraints which can be applied to any value.

Since

Interface available since Release 3.0.0

Member Function Documentation

PHPUnit_Framework_Constraint::additionalFailureDescription (   $other )

protected

Return additional failure description where needed

The function can be overridden to provide additional failure information like a diff

Parameters

mixed

$other

Evaluated value or object.

Returns

string

PHPUnit_Framework_Constraint::count

(

)

Counts the number of constraint elements.

Returns

int

Since

Method available since Release 3.4.0

Implements Countable.

PHPUnit_Framework_Constraint::evaluate	(		$other,
			$description = '',
			$returnResult = false
	)

Evaluates the constraint for parameter $other

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

mixed	$other	Value or object to evaluate.
string	$description	Additional information about the test
bool	$returnResult	Whether to return a result or throw an exception

Returns

mixed

Exceptions

PHPUnit_Framework_ExpectationFailedException

PHPUnit_Framework_Constraint::fail (   $other,   $description, SebastianBergmann\Comparator\ComparisonFailure  $comparisonFailure = null  )

protected

Throws an exception for the given compared value and test description

Parameters

mixed	$other	Evaluated value or object.
string	$description	Additional information about the test
SebastianBergmann\Comparator\ComparisonFailure	$comparisonFailure

Exceptions

PHPUnit_Framework_ExpectationFailedException

PHPUnit_Framework_Constraint::failureDescription (   $other )

protected

Returns the description of the failure

The beginning of failure messages is "Failed asserting that" in most cases. This method should return the second part of that sentence.

To provide additional failure information additionalFailureDescription can be used.

Parameters

mixed

$other

Evaluated value or object.

Returns

string

PHPUnit_Framework_Constraint::matches (   $other )

Evaluates the constraint for parameter $other. Returns true if the constraint is met, false otherwise.

This method can be overridden to implement the evaluation algorithm.

Parameters
