Assert::ok(1 === 1);      //Passed
Assert::ok("a" === "b");  //Failed

Assert::equal("a", "a");  //Passed
Assert::equal(1, 1);      //Passed
Assert::equal(1.0, 2.0);  //Failed

Assert::notEqual("a", "b"); //Passed
Assert::notEqual("a", "a"); //Failed

Assert::throws(() ==> {
    throw new InvalidArgumentException("exception!!");
}, InvalidArgumentException::class);

Custom matcher

You can be the registration of the matcher in the configure method. Matcher specified in the lambda expression.

Assert::configure((ContextBuilder $builder) ==> {

    $builder->registerMatcher('custom_matcher', (...) ==> {
        list($a, $b) = func_get_args();

        if ($a !== $b) {
            throw new AssertionFailedException("custom matcher");
        }
    });

});

Assert::custom_matcher("a", "b");
