Constraint that checks if the file/dir(name) that it is evaluated for is writable.

The file path to check is passed as $other in evaluate().

Methods
public PHPUnit\Framework\Constraint\Constraint::count() : int
 
Counts the number of constraint elements.

public PHPUnit\Framework\Constraint\Constraint::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.

  • throws ExpectationFailedException
  • throws SebastianBergmann\RecursionContext\InvalidArgumentException
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 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.

      protected matches( $other) : bool
       
      Evaluates the constraint for parameter $other. Returns true if the constraint is met, false otherwise.
