Codeception: Check if element has focus?

问题

Is there a way to assert that an element (e.g. input or link) has the keyboard focus? I'm using Codeception with Selenium. Couldn't find anything on http://codeception.com/docs/modules/WebDriver

A reliable source told me this works:

$I->executeJS('return $("#element").is(":focus")');

Happy testing!

Some more details to the answer by @sunomad

Activate Codeception's Asserts Module in your acceptance.suite.yml:

modules:
    enabled:
        # ...
        - Asserts

Then use this in an Acceptance test:

$focus = $I->executeJS('return $("#element").is(":focus")');
$I->assertEquals(true, $focus);

Works (through Selenium) with Firefox and Chrome. However, it does not work with PhantomJS - see this issue: https://github.com/ariya/phantomjs/issues/10427

To complete the @sunomad's answer. If you use the code line :

$I->executeJS('return $("#element").is(":focus")');

You got this error :

[Facebook\WebDriver\Exception\UnknownServerException] unknown error: $ is not a function

Switch $ by jQuery

$I->executeJS('return jQuery("#element").is(":focus")');

And it works !
