的 mock/replay 概念，但是又使用 mocking 定义的闭包范围。
示例代码：
<?php namespace Foo; /** * Here's a class we're trying to test yay. */ class Foo { private $foo = 0; private $incrementing_service = null; public function __construct(Incrementing_Service $incrementing_service) { $this->incrementing_service = $incrementing_service; } public function next_foo() { $this->foo = $this->incrementing_service->increment($this->foo); return $this->foo; } } /** * Our test case runs the same test case twice - once with the original PHPUnit mocking * syntax and a second time with Shmock syntax. */ class Foo_Test extends PHPUnit_Framework_TestCase { use ShmockShmockers; // This enables the use of the Shmock helper methods (replicated below) public function test_phpunit_original_mocking_syntax() { // this is the original PHPUnit mock syntax $incrementing_service_mock = $this->getMock('FooIncrementing_Service', array('increment')); $incrementing_service_mock->expects($this->once()) ->method('increment') ->with($this->equalTo(0)) ->will($this->returnValue(1)); $foo = new Foo($incrementing_service_mock); $this->assertEquals(1, $foo->next_foo(0)); } /** * Create a shmock representation for $class_name and configure expected * mock interaction with $conf_closure * @return Shmock A fully configured mock object * @note You do not need this protected method if you use the Shmockers trait, shown above */ protected function shmock($class_name, $conf_closure) { return ShmockShmock::create_class($this, $class_name, $conf_closure); } public function test_shmock_syntax() { // here's shmock. Neat huh? $incrementing_service_mock = $this->shmock('FooIncrementing_Service', function($shmock) { $shmock->increment(0)->return_value(1); }); $foo = new Foo($incrementing_service_mock); $this->assertEquals(1, $foo->next_foo(0)); } }
