通过Jenkins运行phpunit测试时，如何设置$ _SERVER ['']变量 [英] How to set $_SERVER[' '] variables when running phpunit tests through Jenkins

问题描述

我正在尝试为不可能进行大量代码更改的应用程序编写单元测试.代码库中几乎所有的.php文件都使用一些$ _SERVER ['']变量，例如

I am trying to write unit tests for an application where a lot of code changes is not possible. Almost all the .php files in the code base uses some $_SERVER[''] variables like

require_once $_SERVER['DOCUMENT_ROOT'] . '/mainApi.php';

因此，现在当我不得不编写和运行PHPUnit测试用例时，我必须以某种方式设置这些变量. 目前，我正在用户环境中设置这些变量，然后进行

So now when I have to write and run PHPUnit test cases I have to somehow set these variables. At present I am setting these variables in the user environment and then doing

$_SERVER['DOCUMENT_ROOT'] = getenv('DOCUMENT_ROOT');
require_once $_SERVER['DOCUMENT_ROOT'] . '/mainApi.php';

像这样获取服务器变量工作正常.我通过命令行以$ phpunit test.php的身份运行测试.

Getting the server variables like this is working fine. I run my tests through commandline as $ phpunit test.php.

问题1::可以通过命令行运行phpunit测试时设置$ _SERVER变量吗?

Ques1: Is it possible to set the $_SERVER variables while running the phpunit tests through commandline?

我还必须通过Jenkins运行这些单元测试，但无法通过ANT/build文件设置这些服务器变量.

I also have to run these unit tests through Jenkins and I am not able to set these server variable through ANT/build file.

问题2:是否可以通过Jenkins中的ant构建文件或通过运行任何Shell脚本来设置这些变量，然后再通过Jenkins执行phpunit测试?

Ques2: Is it possible to set these variable through ant build file in Jenkins or by running any shell script before executing the phpunit tests through Jenkins?

我尝试通过shell脚本导出服务器变量

I tried exporting the server variable through a shell script

    export DOCUMENT_ROOT=/server/path-to-root-dir

并在Jenkins的build.xml中调用该脚本

and calling that script in the build.xml in Jenkins

<export name="setEnv" description="set server var">
    <exec executable="sh">
       <arg value = "sumit.sh" />
    </exec> 
</target>

，但不起作用.有什么我可以做的设置吗? 谢谢！

but its not working. Is there any setting that I can do for this? Thanks!

推荐答案

我不确定#1，但是PHPUnit本身必须支持它.我看不到通过命令行执行此操作的任何方法.但是，如果您将当前的解决方法放入bootstrap.php中，则不必在每次测试中都这样做.

I'm not sure about #1, but PHPUnit itself would have to support it. I don't see any way to do that via the command line. However, if you put your current workaround into bootstrap.php you don't have to do it in each test.

对于#2， <exec> 允许您使用以下命令设置环境变量嵌套的<env>元素.我在詹金斯(Jenkins)中使用它.

For #2, <exec> allows you to set environment variables using nested <env> elements. I use this in Jenkins.

<exec executable="phpunit" ...>
    <env key="DOCUMENT_ROOT" value="/var/www/php"/>
</exec>

更新:通常，您创建bootstrap.php来设置将源目录添加到包含路径，并根据需要初始化测试环境.该文件不是由PHPUnit提供的，与phpunit.xml不同.

Update: You typically create bootstrap.php to setup add the source directory to the include path and initialize the test environment however you need. This file isn't supplied by PHPUnit--unlike phpunit.xml.

我将其放置在与phpunit.xml相同的目录中，但这是因为每个项目都有一个单独的文件.它进入通常保存测试的目录中.这样，您就可以从命令行运行phpunit，而无需告诉它如何查找那些配置文件.否则，您必须使用--bootstrap和/或--configuration指向它们.

I place it in the same directory as phpunit.xml, but that's because I have a separate file for each project. It goes in the directory that holds your tests typically. This allows you to run phpunit from the command-line without telling it how to find those configuration files. Otherwise you have to use --bootstrap and/or --configuration to point to them.

这是我构建典型项目的方式:

Here is how I structure a typical project:

<project-root>/
    build.xml
    src/
        MyClass.php
    test/
        MyClassTest.php
        phpunit.xml
        bootstrap.php
