How can I get PHPUnit MockObjects to return different values based on a parameter?

Question

I\'ve got a PHPUnit mock object that returns \'return value\' no matter what its arguments:

// From inside a test...
$mock = $this->getMock(\

$this->BusinessMock = $this->createMock('AppBundle\Entity\Business');

    public function testBusiness()
    {
        /*
            onConcecutiveCalls : Whether you want that the Stub returns differents values when it will be called .
        */
        $this->BusinessMock ->method('getEmployees')
                                ->will($this->onConsecutiveCalls(
                                            $this->returnArgument(0),
                                            $this->returnValue('employee')                                      
                                            )
                                      );
        // first call

        $this->assertInstanceOf( //$this->returnArgument(0),
                'argument',
                $this->BusinessMock->getEmployees()
                );
       // second call


        $this->assertEquals('employee',$this->BusinessMock->getEmployees()) 
      //$this->returnValue('employee'),


    }
