$mockDb = $this->getMockBuilder('Database') ->setMethods(array('getById')) ->getMock(); $mockDb->expects($this->once()) ->method('getById') ->with($this->equalTo(1)) ->willReturn(new Object(1, 'Name')); $object = $mockDb->getById(1); $this->assertInstanceOf('Object', $object); $this->assertEquals(1, $object->getId());
$mockObject = $this->getMockBuilder('Object') ->getMock(); $mockObject->expects($this->once()) ->method('setId') ->with($this->equalTo(1)); $mockObject->setId(1); $this->assertEquals(1, $mockObject->getId());In both examples, PHPUnit_Framework_MockObject_MockObject is used to create a mock object for testing. The getId method is then used to retrieve the identifier for the mock object, which is then compared to the expected value. The PHPUnit package library is used to provide the necessary tools for unit testing in PHP.
