When the \Behat\Mink\Tests\Driver\Js\EventsTest::testRightClick test is executed on Selenium 3.x it fails with this message:
Failed asserting that two strings are equal.
Expected :'right clicked'
Actual :'single clicked'
The driver code seems to be written correctly (I've double-checked with the Facebook's driver version: https://github.com/php-webdriver/php-webdriver/blob/5d8e66ff849b5614015d35e99d759252e371ce26/lib/Remote/RemoteMouse.php#L100 ).
Not sure why the test fails.
More research is done in #354 (comment) .
The fix was done in #372 , but it's using Actions , which isn't implemented in the WebDriver.
