Expect a method to be never called with certain arguments

Question

In PHPUnit how can I test if a method is never called with certain arguments? I mean that it can be called with any other arguments even multiple times but never with a certain one.

Looks like it's not possible using the standard way so you can use a callback for specifying the return value, and check the arguments there (bit tricky but seems to work):

$mock = $thi->getMockBuilder('MyClass')->getMock();
$mock->expects($this->any())
     ->method('myMethod')
     ->willReturnCallback(function() {
        $args = func_get_args();
        $disallowedArgs = [1, 'abc'];
        $this->assertNotEquals($disallowedArgs, $args);
    })
;
