PHPUnit mock raises incompatible declaration error

Question

I am using PHPUnit 3.6.10 (unfortunately, I can’t upgrade to a newer version now). Dealing with a mockery of some outdated code, I got a strange error. I tried Google, only the results related to static methods appeared, which is not my business.

The presence of this class:

 class ServicesMapper extends DbMapper { //... (some methods) public function saveTravel(ServiceTravel $oTravel) { $this->getAdapter()->insert('services_travels', $oTravel->getToArray()); } //... (some methods) } 

I am trying to mock this:

(inside unit test class)

 /** * @return ServicesMapper */ private function getServicesMapperStub() { $stub = $this->getMock('ServicesMapper'); $stub->expects($this->any()) ->method('searchBy') ->will($this->returnValue(array())); return $stub; } 

Now, during the execution of this fake test (I know that this test does nothing, it just shows the problem):

  /** * @test */ public function fakeMockTest(){ $serviceMapper = $this->getServicesMapperStub(); $this->assertTrue(true); } 

I get this error:

 Declaration of Mock_ServicesMapper_60b00178::saveTravel() should be compatible with ServicesMapper::saveTravel(ServiceTravel $oTravel) 

I use this style of bullying in many places, it works well, except in this particular case. What is wrong with my code?

BTW: I also tried to solve this problem by mocking the saveTravel method, with no luck.

Your code looks correct and can work with simple stubs, and not mock (basically, a stub with expectations).

For mocks you need to do:

 $mock = $this->getMockBuilder('ServicesMapper') ->setMethods(array ('searchBy')) ->getMock(); 

All methods that you want to set for expectations must be declared on setMethods ().
