软件简介

Shmock（SHorthand for MOCKing）是 PHPUnit 创建
mocks 的平稳替代，使用 EasyMock 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 \Shmock\Shmockers; // 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('\Foo\Incrementing_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, $conf_closure)
        {
            return \Shmock\Shmock::create_class($this, $class_name, $conf_closure);
        }

        public function test_shmock_syntax()
        {
            // here's shmock. Neat huh?
            $incrementing_service_mock = $this->shmock('\Foo\Incrementing_Service', function($shmock)
            {
                $shmock->increment(0)->return_value(1);
            });

            $foo = new Foo($incrementing_service_mock);
            $this->assertEquals(1, $foo->next_foo(0));
        }
    }
