Methods
public count() : int
 
Counts the number of constraint elements.

public evaluate( $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.

    public toString() : string
     
    Returns a string representation of the constraint.

    Methods
    protected PHPUnit\Framework\Constraint\Constraint::additionalFailureDescription( $other) : string
     
    Return additional failure description where needed

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

      protected PHPUnit\Framework\Constraint\Constraint::exporter() : SebastianBergmann\Exporter\Exporter
      protected PHPUnit\Framework\Constraint\Constraint::fail( $other, $description, ?SebastianBergmann\Comparator\ComparisonFailure $comparisonFailure = NULL) : void
       
      Throws an exception for the given compared value and test description

      • throws ExpectationFailedException
      • throws SebastianBergmann\RecursionContext\InvalidArgumentException
      protected PHPUnit\Framework\Constraint\Constraint::failureDescription( $other) : string
       
      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.

      • throws SebastianBergmann\RecursionContext\InvalidArgumentException
      protected PHPUnit\Framework\Constraint\Constraint::matches( $other) : bool
       
      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.
