PHP Native Mock

Helper class to mock or redefine native PHP functions in unit tests. Works using the UOPZ module, developed and tested against the master branch.

This is largely a wrapper around the uopz functions with some extra bits thrown in to make it a bit easier in tests. It basically relies on dark magic and, like all magic, should only be used very carefully. Creating weird behaviour in applications is very easy, for example

$this->redefineFunction('substr', function () {
    return 'Doge';
});

would have some very strange effects.

Most of the time when redefining a function sounds like a good idea - it's probably not, make sure there is no way a "normal" mocking approach won't work first.

Installation

The library can be included via composer

{
    "require-dev": {
        "betterphp/php-native-mock": "~1"
    }
}

Testing

We use phpcs and phpunit for testing, run both before commiting anything

./vendor/bin/phpcs -p --standard=./ruleset.xml .

./vendor/bin/phpunit -c ./phpunit.xml

phpunit will do code coverage checking which requires xdebug, if it's not installed this will fail gracefully - not to worry.

A report of the test coverage is published here by Jenkins
