phpunit - 无法使用 CodeCoverage 和 Composer 重新声明类错误

Question

使用 Composer 的 autoload.php 作为引导文件时，我遇到 PHPUnit Code_Coverage 错误。我创建了自己的 boostrap.php 文件，只需单独包含每个文件即可，一切正常。我是否偶然发现了 Composer 错误，或者我在某个地方犯了错误？

//编辑:我正在使用所有内容的最新(最新)版本:PHPUnit 3.7.12、Code_Coverage 1.2.7、Composer b51a4a7

问题出在我在项目中使用命名空间。我的项目命名空间是 C3\CDN\EdgeCast(注意 EdgeCast 中的大写“C”)，但是当我在测试文件中使用该命名空间时，我不小心输入了 use C3\CDN\Edgecast; (注意 Edgecast 中的小写“c”)。名称的差异导致 CodeCoverage 或 Composer(我不知道到底是哪一个)认为该类尚未包含在内，因此尝试再次包含它。

这个故事的寓意:始终仔细检查您的类和命名空间名称。
