如何设置 Laravel Boilerplate phpunit 以在 Homestead 环境中提供代码覆盖率

Question

我有一个运行完美的全新 Laravel Boilerplate running on a Laravel Homestead 环境。 php -v 命令向我返回此信息

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.

我正在搜索如何设置 phpunit 的代码覆盖率以工作，发现我需要 xDebug 才能使其工作。在谷歌上搜索了一下，找到了 xon homestead 命令，它启用了 xDebug 扩展。所以我运行它，发现 xDebug 扩展已启用，如新的 php -v 所示：

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

我还需要添加 php-code-coverage 与 composer require --dev phpunit/php-code-coverage:4.0.8 的依赖关系（特定版本，因为我在尝试安装最新版本时遇到了一些需求错误）。

然后我运行 phpunit --coverage-clover=coverage.xml 得到了这个致命错误：

我感觉这与 Laravel Facades 有关，这让我认为 phpunit 不是运行我的自动加载文件，而是属性 bootstrap="bootstrap/autoload.php"默认存在于phpunit.xml个文件中。

不知道从哪里开始，不知道哪里出了问题。

编辑：我的 Homestead 版本是 5.1.0

Answer 1

新的样板安装带有一个 phpunit.xml 文件。在其中，有一个带有此数据的过滤器标签

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

我不是 PHPUnit 专家，所以我玩了一下 XML，发现 whitelist 标签导致它崩溃。我又玩了一会儿，发现如果我删除 processUncoveredFilesFromWhitelist="true" 属性，phpunit 命令能够运行并生成我需要的代码覆盖率。

请注意。

不幸的是，如果没有代码覆盖测试，过去运行需要约 1.5 分钟，而使用此技巧打开代码覆盖，测试需要约 11 分钟。

由于问题与生成代码覆盖率报告有关，我会将其标记为已接受，如果我发现任何可能对遇到与我相同问题的人有帮助的内容，我会保持更新此问题。
