Joe*_*phy 5 python unit-testing overriding python-2.7 python-unittest
编辑:解决了!
将很快用解决方案更新.
目标:
我想重写Python的UnitTest模块,所以当我调用它时,我在stdout流中得到以下JSON输出.例如:
{
"errors":0,
"failures":1,
"ran":3,
"skipped":0,
"successful":2,
"test_data":[
{
"index":0,
"result":1
},
{
"index":1,
"result":1
},
{
"index":2,
"result":-1
}
]
}
问题:
我已经编写了一些代码来生成这些测试结果,但是我遇到了为test_dataJSON数组的属性编写代码的问题.我已经重写了TestCase,TextTestResult而且TextTestRunner类,但我似乎无法弄清楚如何从得到的结果getTestsReport():
#!/usr/bin/python

class dataHolder(object):
x = None
class MyTestRunner(unittest.TextTestRunner):
def _makeResult(self):
obj = MyTestResult(self.stream, self.descriptions, self.verbosity)
dataHolder.x = obj.getTestsReport()
return obj
class MyTestResult(unittest._TextTestResult):

MyTestRunner( stream=None, descriptions=0, verbosity=0 )
unittest.main(exit=False)
x调用后为什么不更新值getTestsReport()？
编辑:
好吧,我认为unittest.main(exit=False)是错误的功能!我现在正在尝试重写我的主要代码,但仍面临一系列问题:

有人可以帮帮我吗？我好卡住了:(
