在phpunit测试中回显 [英] echo in phpunit tests

问题描述

我一直在尝试在phpunit测试中添加echo内容，但到目前为止还没有运气.

I have been trying to echo stuff in my phpunit tests but no luck so far.

我阅读了有关xml配置文件的文档，显然debug参数正是我想要的.不幸的是，它仍然无法正常工作.无论如何，这是我的xml配置文件:

I read the documentation about the xml config file and apparently the debug parameter is what I am looking for. Unfortunately it still doesn't work. Anyhow here is my xml config file:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit colors="true"
         processIsolation="true"
         verbose="true"
         debug="true">
</phpunit> 

接受processIsolation和verbose，但不接受debug.

当我将命令直接传递给phpunit时，该命令实际上可以正常工作

The command actually works pretty fine when I directly pass it to phpunit like this:

phpunit --debug MyTest.php # here stuff is echoed correctly

但是使用xml配置文件，它似乎被忽略了.

but with the xml config file it looks like it is ignored.

推荐答案

PHPUnit >3.6.4的当前版本(以及所有3.5.*版本)将在测试用例中仅打印您echo的所有内容.

Current versions of PHPUnit >3.6.4 (and all 3.5.* versions) will just print everything you echo in a test case.

<?php

class OutputTestCase extends PHPUnit_Framework_TestCase {

    public function testEcho() {
        echo "Hi";
    }   
}

产生:

phpunit foo.php 
PHPUnit 3.6.7 by Sebastian Bergmann.

.Hi

Time: 0 seconds, Memory: 3.25Mb

OK (1 test, 0 assertions)

因此，如果您使用的是旧版3.6，只需升级:)

So if you are on an old 3.6 version just upgrade :)
