## NAME
    [Test2::EventFacet::Assert](https://www.chedong.com/phpMan.php/perldoc/Test2%3A%3AEventFacet%3A%3AAssert/markdown) - Facet representing an assertion.

## DESCRIPTION
    The assertion facet is provided by any event representing an assertion that was made.

## FIELDS
    $string = $assert->{details}
    $string = $assert->details()
        Human readable description of the assertion.

    $bool = $assert->{pass}
    $bool = $assert->pass()
        True if the assertion passed.

    $bool = $assert->{no_debug}
    $bool = $assert->no_debug()
        Set this to true if you have provided custom diagnostics and do not want the defaults to be
        displayed.

    $int = $assert->{number}
    $int = $assert->number()
        (Optional) assertion number. This may be omitted or ignored. This is usually only useful
        when parsing/processing TAP.

        Note: This is not set by the Test2 system, assertion number is not known until AFTER the
        assertion has been processed. This attribute is part of the spec only for harnesses.
