当我在shell中运行PhpUnit测试时，它们运行正常，但是当从Jenkin的构建步骤（Execute Shell）运行时，它失败了：
[workspace] $ /bin/sh -xe /tmp/hudson3868615221631158667.sh

我发现了一些类似的问题，但没有人回答/解决我的问题。
以下是从shell运行的结果：
user@server:~/$ phpunit --log-junit trunk/tests/phpunit_results.xml --bootstrap trunk/tests/bootstrap.php trunk/tests/
ccccPHPUnit 4.1.3 by Sebastian Bergmann.
.......
Time: 128 ms, Memory: 6.75Mb
OK (7 tests, 8 assertions)
我欢迎每一个建议。
