如何在执行 PHP 单元测试期间在 CLI 中输出? [英] How to output in CLI during execution of PHP Unit tests?

问题描述

在运行 PHPUnit 测试时，我希望能够转储输出，以便调试一两件事.

我尝试了以下(类似于 PHPUnit 手册示例);

class theTest 扩展 PHPUnit_Framework_TestCase{/*** @outputBuffering 禁用*/公共函数 testOutput() {print_r("你好世界");打印平"；echo "乒乓";$out = "Foo";var_dump($out);}}

结果如下:

PHPUnit @package_version@ ​​由 Sebastian Bergmann..时间:0 秒，内存:3.00MbOK(1 个测试，0 个断言)

注意没有任何预期的输出.

截至 2011 年 9 月 19 日，我使用的是 git repos 的 HEAD 版本.>

php -version 的输出:

$ php -versionPHP 5.2.9 (cli)(构建时间:2010 年 12 月 8 日 11:36:37)版权所有 (c) 1997-2009 The PHP GroupZend Engine v2.2.0，版权所有 (c) 1998-2009 Zend Technologies使用 Xdebug v2.1.0，版权所有 (c) 2002-2010，Derick Rethans

我做错了什么，或者这可能是 PHPUnit 的错误吗?

解决方案

UPDATE

刚刚发现另一种比 --verbose 命令行选项更有效的方法:

class TestSomething 扩展 PHPUnit_Framework_TestCase {函数 testSomething() {$myDebugVar = 数组(1, 2, 3);fwrite(STDERR, print_r($myDebugVar, TRUE));}}

这让您可以随时将任何内容转储到您的控制台，而不会出现 --verbose CLI 选项附带的所有不需要的输出.

正如其他答案所指出的，最好使用内置方法测试输出，例如:

$this->expectOutputString('foo');

但是，有时调皮并从测试用例中查看一次性/临时调试输出是有帮助的.但是，不需要 var_dump hack/解决方法.这可以通过在运行测试套件时设置 --verbose 命令行选项来轻松完成.例如:

$ phpunit --verbose -c phpunit.xml

这将显示在 CLI 环境中运行时测试方法内部的输出.

参见:为 PHPUnit 编写测试 - 测试输出.

When running a PHPUnit test, I would like to be able to dump output so I can debug one or two things.

I have tried the following (similar to the PHPUnit Manual example);

class theTest extends PHPUnit_Framework_TestCase
{
    /**
     * @outputBuffering disabled
     */
    public function testOutput() {
        print_r("Hello World");
        print "Ping";
        echo "Pong";
        $out = "Foo";
        var_dump($out);
    }   
}

With the following result:

PHPUnit @package_version@ by Sebastian Bergmann.

.

Time: 0 seconds, Memory: 3.00Mb

OK (1 test, 0 assertions)

Notice there is none of the expected output.

I'm using the HEAD versions of the git repos as of September 19th, 2011.

Output of php -version:

$ php -version
PHP 5.2.9 (cli) (built: Dec  8 2010 11:36:37) 
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
    with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans

Is there anything I'm doing wrong, or is this potentially a PHPUnit bug?

解决方案

UPDATE

Just realized another way to do this that works much better than the --verbose command line option:

class TestSomething extends PHPUnit_Framework_TestCase {
    function testSomething() {
        $myDebugVar = array(1, 2, 3);
        fwrite(STDERR, print_r($myDebugVar, TRUE));
    }
}

This lets you dump anything to your console at any time without all the unwanted output that comes along with the --verbose CLI option.

As other answers have noted, it's best to test output using the built-in methods like:

$this->expectOutputString('foo');

However, sometimes it's helpful to be naughty and see one-off/temporary debugging output from within your test cases. There is no need for the var_dump hack/workaround, though. This can easily be accomplished by setting the --verbose command line option when running your test suite. For example:

$ phpunit --verbose -c phpunit.xml

This will display output from inside your test methods when running in the CLI environment.
