Parameters

int|float $value

mixed evaluate(mixed $other, string $description = '', bool $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

Return Value

mixed

protected bool matches(mixed $other)

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

Parameters

mixed $other Value or object to evaluate.

Return Value

bool

int count()

Counts the number of constraint elements.

protected fail(mixed $other, string $description, ComparisonFailure $comparisonFailure = null)

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
ComparisonFailure $comparisonFailure

Exceptions

ExpectationFailedException

protected string additionalFailureDescription(mixed $other)

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.

Return Value

string

protected string failureDescription(mixed $other)

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.

Return Value

string

at line 51
string toString()

Returns a string representation of the constraint.

Return Value
