使用unittest discover启动的测试无法导入某些模块

Question

所以我从头做了一个python项目，我的测试在eclipse / pydev中运行正常但是当我使用discover命令行时它们没有。

结构：

运行discover命令时我得到了什么：

qzdqzdqzd@dgdrgdrrdg /d/AAA_Dev2015/Checkouts/web/tools/ideal-checker/tests (cpatitest)
$ python -m unittest discover -v -p '*_test.py'

你知道吗？ 感谢。

修改

我尝试在每个测试用例中自己加载src文件夹，但它不起作用

@classmethod
def setUpClass(cls):
    sys.path.insert(0, '../../src')
