如何返回模拟方法的参数？

Question

大家好我怎么能在PHPUnit中做到这一点,一个模拟方法返回它传递的参数？

例如:

$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
            ));
