对于以下test_checkListItem()
模块,我的上述测试filterList
失败:
import sys
import ast
class ItemNotString(Exception):
pass
class FilterList(object):
"""docstring for FilterList
"""
def __init__(self, lst, filterby):
super(FilterList, self).__init__()
self.lst = lst
self._filter = filterby
self.checkListItem()
def checkListItem(self):
for index, item in enumerate(self.lst):
if type(item) == str:
continue
else:
raise ItemNotString("%i item '%s' is not of type string" % (index+1, item))
print self.filterList()
return True
def filterList(self):
filteredList = []
for eachItem in self.lst:
if eachItem.startswith(self._filter):
filteredList.append(eachItem)
return filteredList
if __name__ == "__main__":
try:
filterby = sys.argv[2]
except IndexError:
filterby = 'H'
flObj = FilterList(ast.literal_eval(sys.argv[1]), filterby)
#flObj.checkListItem()
为什么测试因错误而失败:
======================================================================
ERROR: test_checkListItem (__main__.TestFilterList)

此外,filterList
模块的方法是否正确?
答案 0 :(得分:1)
您的assertRaises
来电未触及异常,因为它是在上一行引发的。如果仔细查看回溯,您会看到checkListItem
类的FilterList
方法调用了__init__
,当您尝试创建self.flObj
时,该方法又会被调用在你的测试中。
