我正在练习非常基本的单元测试，并且代码工作正常。但每次测试失败时，我都会收到以下错误，导致无法显示测试的完整失败消息：

Answer 1

此PHP_Invoker错误的根本原因似乎是在自动加载器中。

当PHPunit运行时，它会使用class_exists函数检查某些类是否存在。默认情况下，此函数尝试使用自动加载器加载类。

如果自动加载器实现在找不到类时失败，那么您将遇到此错误。

导致故障的自动加载器实现示例如下。如果找不到该文件，require_once将失败。

function AutoLoader($className)
{
  $file = __DIR__ . DIRECTORY_SEPARATOR . str_replace('\\',DIRECTORY_SEPARATOR,$className) . ".php";
  require_once($file);
}

如果您有自己的自动加载器，一种解决方案是在那里添加file_exists检查：

function AutoLoader($className)
{
  $file = __DIR__ . DIRECTORY_SEPARATOR . str_replace('\\',DIRECTORY_SEPARATOR,$className) . ".php";
  if(file_exists($file)
    require_once($file);
}

Answer 2

PHP_Invoker是PHPUnit的可选依赖项。您不应手动包含PHP/Invoker.php（或任何软件包的源文件）。

Phpunit - 致命错误：require（）：无法打开所需的PHP \ Invoker.php＆＃39;
