我有当前的travis.yml在我的 Github 上：
# see http://about.travis-ci.org/docs/user/languages/php/ for more hints
language: php
# list any PHP version you want to test against
php:
# aliased to a recent 5.4.x version
- 5.4
# aliased to a recent 5.5.x version
- 5.5
我所有的工作都在失败，但是在一个简约的构建中，我看不出它失败的原因..因为特拉维斯并没有完全掌握最好的信息..这是我日志的最后几块：

和约伯记 9.2：
相同并以以下结尾：
The command "phpunit" exited with 2.
Done. Your build exited with 1.
