Constraint that checks if one value is equal to another.

Equality is checked with PHP's == operator, the operator is explained in
detail at {@url}.
Two values are equal if they have the same value disregarding type.

The expected value is passed in the constructor.

public __construct( $value, float $delta = 0, int $maxDepth = 10, bool $canonicalize = false, bool $ignoreCase = false)
public PHPUnit\Framework\Constraint\Constraint::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
public toString() : string

Returns a string representation of the constraint.

  • throws SebastianBergmann\RecursionContext\InvalidArgumentException
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.
