How to test a second parameter in a PHPUnit mock object

This is what I have:

$observer = $this->getMock('SomeObserverClass', array('method'));
$observer->expects($this->once())
         ->method('method')
         ->with($this->equalTo($arg1));

But the method should take two parameters. I am only testing that the first parameter is being passed correctly (as $arg1).

How do test the second parameter?

Solution 1:

I believe the way to do this is:

$observer->expects($this->once())
     ->method('method')
     ->with($this->equalTo($arg1),$this->equalTo($arg2));

Or

$observer->expects($this->once())
     ->method('method')
     ->with($arg1, $arg2);

If you need to perform a different type of assertion on the 2nd arg, you can do that, too:

$observer->expects($this->once())
     ->method('method')
     ->with($this->equalTo($arg1),$this->stringContains('some_string'));

If you need to make sure some argument passes multiple assertions, use logicalAnd()

$observer->expects($this->once())
     ->method('method')
     ->with($this->logicalAnd($this->stringContains('a'), $this->stringContains('b')));
