public __construct( $constraint)
    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

    • throws ExpectationFailedException
    • throws SebastianBergmann\RecursionContext\InvalidArgumentException
    public static negate(string $string) : string
    public toString() : string

    Returns a string representation of the constraint.

    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 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.

      • 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.
