PHP-Runkit的替代品，用于拦截方法调用 [英] PHP - Alternatives to runkit for intercepting method calls

问题描述

我有一些非常难以测试的代码(至少可以说)需要测试.不幸的是，重构不是一种选择.我必须按原样测试代码，而不能更改它.

I have some very test-unfriendly code (to say the least) that I need to test. Refactoring unfortunately is not an option. I have to test the code as it is, without the possibility of changing it.

为此，我正在考虑拦截函数调用并动态更改它们的操作，以便可以运行测试，因为我需要一些函数和方法来返回已知值，并且我需要其他函数和方法来进行请求，并连接到数据库等，以停止这样做并返回我需要它们返回的内容.没有 runkit_method_redefine() ，有没有办法做到这一点? ，最好不是"EXPERIMENTAL"，并且仍然保持?也许替代runkit?也许更好的方法?

To do that, I was thinking of intercepting function calls and dynamically change what they do so I can run my tests, as I need some functions and methods to return known values, and I need others that make requests, connect to the database, etc, to stop doing that and return what I need them to return. Is there any way to do this without runkit_method_redefine(), which is preferably not "EXPERIMENTAL" and still maintained? Maybe an alternative to runkit? Maybe a better way?

如果需要，将使用PHPUnit的测试双精度和PHP 5.3.2的功能来使私有方法可访问.

will use PHPUnit's test doubles and PHP 5.3.2's features for making private methods accessible, if I need that functionality.

推荐答案

注意: Test-Helper扩展已被 a href ="https://github.com/krakjoe/uopz" rel ="nofollow"> https://github.com/krakjoe/uopz

Note: the Test-Helper extension is superseded by https://github.com/krakjoe/uopz

PHPUnit 的测试帮助程序扩展(PECL)允许定义/拦截/接受/模拟硬编码依赖项您自己的实现:

PHPUnit's Test Helper extension (PECL) allows redefiniton/intercepting/stubbing/mocking of hardcoded dependencies with your own implementations:

protected function setUp()
{
    $this->getMock(
      'Bar',                    /* name of class to mock     */
      array('doSomethingElse'), /* list of methods to mock   */
      array(),                  /* constructor arguments     */
      'BarMock'                 /* name for mocked class     */
    );

    set_new_overload(array($this, 'newCallback'));
}

它还允许拦截exit语句和实例创建:

It also allows intercepting the exit statement and instance creation:

对于存根和模拟方法，您只需使用PHPUnit的常规模拟框架.参见

For stubbing and mocking methods you simply use PHPUnit's regular mocking framework. See

• http://www.phpunit.de/manual/current/zh/test-doubles.html

您还可以将Mockery与PHPUnit一起使用:

You can also use Mockery with PHPUnit:

另一种选择是使用 http://antecedent.github.io/patchwork

Patchwork是一个PHP库，可以在运行时重新定义用户定义的函数和方法，以纯PHP 5.3代码轻松地复制功能runkit_function_redefine，除其他外，该函数使您可以替换静态和私有方法.加上测试双打.

Patchwork is a PHP library that makes it possible to redefine user-defined functions and methods at runtime, loosely replicating the functionality runkit_function_redefine in pure PHP 5.3 code, which, among other things, enables you to replace static and private methods with test doubles.
