如何在宅基地环境下设置Laravel样板单元以提供代码覆盖

Question

我有一个新的Laravel样板运行在运行完美的拉勒维尔家园环境上。php -v命令返回给我这个信息

PHP 7.1.2-3+deb.sury.org~xenial+1 (cli) (built: Feb 22 2017 10:08:33) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache v7.1.2-3+deb.sury.org~xenial+1, Copyright (c) 1999-2017, by Zend Technologies
    with blackfire v1.14.3~linux-x64-non_zts71, https://blackfire.io, by Blackfireio Inc.

我在搜索如何设置phpunit的代码覆盖率以使其工作，并发现我需要xDebug来使其工作。谷歌搜索了更多的内容，找到了支持xon扩展的xDebug more命令。因此，我运行它，并发现启用了xDebug扩展，就像一个新的php -v显示的那样：

PHP 7.1.2-3+deb.sury.org~xenial+1 (cli) (built: Feb 22 2017 10:08:33) ( NTS )

另外，我还需要使用composer require --dev phpunit/php-code-coverage:4.0.8 (特定版本)添加php代码覆盖率依赖项(因为我在安装最新版本时遇到了一些需求错误)。

然后运行phpunit --coverage-clover=coverage.xml，得到了一个致命的错误：

我觉得这与Laravel外观有关，这使我认为phpunit没有运行我的autoload文件，但是默认情况下，属性bootstrap="bootstrap/autoload.php"存在于phpunit.xml文件中。

不知道从这里往哪里走，不知道是怎么回事。

编辑:我的家园版是5.1.0

Answer 1

新的样板安装附带一个phpunit.xml文件。在它里面，有一个过滤器标记，其中包含这些数据。

<filter>
    <whitelist processUncoveredFilesFromWhitelist="true">
        <directory suffix=".php">
            ./app
        </directory>
    </whitelist>
</filter>

我不是PHPUnit专家，所以我稍微玩了一下whitelist，发现whitelist标记导致了它的崩溃。我更多地使用了它，并发现如果删除processUncoveredFilesFromWhitelist="true"属性，phpunit命令就能够运行并生成所需的代码覆盖率。

只是一张纸条。

不幸的是，如果没有代码覆盖率测试，运行时间通常为1.5分钟，而使用此技巧打开代码覆盖率，则测试将花费11分钟。

由于这个问题与生成代码覆盖率报告有关，我将将其标记为已接受，如果我发现可能帮助与我有相同问题的人的任何事情，我将保持此问题的更新。
