php - How to return the argument of a mocked method?

Question

Hi all how can I make it so in PHPUnit a mocked method returns its passed argument?

E.g:

$redirector->expects( $this->once() )->method('gotoUrl')->will( $this->returnValue($argument) );

Answer 1

根据PHPUnit 手册：

$stub->expects($this->any())
     ->method('doSomething')
     ->will($this->returnArgument(0));

Answer 2

$redirector->expects($this->once())
           ->method('gotoUrl')
           ->will($this->returnCallback(function() {
                $args = func_get_args();
                return $args[0]; // or w/e
            ));
