在命令行上将参数发送到PHP Unit [英] Send parameter to PHP Unit on the command line

问题描述

我想使用命令行将参数发送到PHP Unit.

I want to send a parameter to PHP Unit using the command line.

例如

./phpunit --foo='bar' AllTests

我该怎么做?

我能够实现的最接近目标是使用以下内容:

The closest I was able to achieve my objective is using the following:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit>
    <php>
        <env name="foo" value="bar"/>
    </php>
</phpunit>

然后我可以使用$_ENV['foo']访问该变量.

I can then access the variable using $_ENV['foo'].

但是，我想使用命令行发送此变量.

However, I want to send this variable using the command line.

推荐答案

使用phpunit.xml显然是用于恒定的环境变量，并且使用它来将更改的参数传递给测试会有点麻烦.

Using phpunit.xml is obviously for constant environmental variables and using it for passing changing parameters to tests is a bit of an overhead.

您可以执行以下操作之一(请参阅将参数传递给PHPUnit 讨论):

What you can do is one of the following (see Passing parameters to PHPUnit for the discussion):

示例: FOO=bar ./phpunit AllTests

优点:很简单.

缺点:取决于环境；需要记住变量的名称(如果有很多的话就不那么简单了)；没有明显的支持/必需参数的文档.

Cons: Depends on environment; requires remembering names of the variables (which is not that simple if there are many); no obvious documentation on supported/necessary parameters available.

示例: ./phpunit AllTests bar

优点:微不足道；独立于环境；对PHPUnit参数没有限制.

Pros: Trivial; independent from environment; no limitations to PHPUnit parameters.

缺点::如果有多个参数，尤其是大多数参数是可选的，那将是一件痛苦的事情.没有关于预期参数的明显文档.

Cons: Will be a pain if there are more than several arguments, especially if most of them are optional; no obvious documentation for expected arguments.

示例: . run.sh AllTests bar其中，run.sh查看所提供的参数并将其导出到环境中.

Example: . run.sh AllTests bar where run.sh looks at the provided arguments and exports them into the environment.

优点:实施起来还是比较琐碎的；添加预期参数列表的文档；添加错误处理(例如，如果bar是必需参数，但未提供).

Pros: Still more or less trivial to implement; adds documentation of the expected argument list; adds error handling (e.g. in case bar is a required parameter, but is not provided).

缺点::runner中的PHPUnit参数是硬编码的；取决于环境.

Cons: PHPUnit parameters inside runner are hardcoded; dependent on the environment.

示例: ./phpunit --foo='bar' AllTests

优点:完全满足您的要求.

缺点:实施起来并不容易；需要进行分叉，这使其严重依赖于当前PHPUnit版本的CLI.

Cons: Not so trivial to implement; requires forking which makes it strongly dependent on CLI of the current PHPUnit version.

示例: run.sh --foo=bar --coverage-html=baz其中run.sh调用一些run.php，该c10随后通过解析器运行命令参数，构建用于运行测试的命令并执行该操作.

Example: run.sh --foo=bar --coverage-html=baz where run.sh calls some run.php which in its turn runs command arguments through parser, builds the command for running tests and does that.

优点:现在，您可以执行任何操作并添加所需的任何参数.您可以实现自己的记录器，也可以在多线程中运行测试.

Pros: Now you can do whatever you like and add any parameters you need. You can implement your own logger, you can run tests in multithread etc.

缺点:难以实施；有时需要维护；强烈依赖于PHPUnit CLI.

Cons: Hard to implement; sometimes needs maintenance; is strongly dependent on PHPUnit CLI.
