Restric types after assertion

[Jean85]

I'm using static analysis (PHPStan, Psalm) on my tests, and with the appropriate extensions they are able to restrict types after I've applied assertions.

$this->assertIsString($foo);
// $foo is string now

$this->assertIsInstanceOf(Bar::class, $foo);
// $foo is a Bar instance

Would it be possible to do the same here? It would enable autocomplete os such variables, and suppress warning due to unknown types.

its not related to this plugin, the methods having the docblock describing the behavior.

https://github.com/Haehnchen/idea-php-generics-plugin you can look at this plugin; some docblock are already support.

How can you add PhpDoc yourself to methods for PHPUnit?

PHPUnit is already having the docblock: https://github.com/sebastianbergmann/phpunit/blob/master/src/Framework/Assert.php#L1324
