我的程序的 Unittest 模块实现出现以下错误
File "/usr/lib/python2.7/unittest/case.py", line 493, in _getAssertEqualityFunc
asserter = self._type_equality_funcs.get(type(first))
AttributeError: 'Utility' object has no attribute '_type_equality_funcs'
当我尝试创建一个公共类并尝试通过公共类实用程序测试函数执行时出现上述错误,但使用正常的 Unittest 类实现时没有出现错误。
下面是执行没有任何错误的程序的详细说明
class BaseTestCase(unittest.TestCase):
def __init__(self, methodName='runTest', param=None):
super(BaseTestCase, self).__init__(methodName)
self.param = param
@staticmethod
def parametrize(testcase_klass, param=None):
testloader = unittest.TestLoader()
testnames = testloader.getTestCaseNames(testcase_klass)
suite = unittest.TestSuite()
for name in testnames:
suite.addTest(testcase_klass(name, param=param))
return suite
现在我继承基本测试用例类并调用测试用例..
class salesgrowth_DevInt(BaseTestCase):
def setUp(self):
print "constructor"
pwd = os.getcwd()
def test4_refactoring(self,log):
if (STATUS.lower() == "completed" or STATUS == "Actor : SUCCESS"):`enter code here`
self.assertEqual(os.stat(OUTPUT + '/tes1.txt').st_size, 0,
'employee count is not matching with master data . Different entries are in test1.txt\n')
到目前为止一切正常
现在像 salesgrowth_DevInt 测试用例一样,没有其他测试用例继承 BaseTestCase 并执行 test4_refactoring 测试用例(这里例如测试用例没有删除行),以避免代码重复
我创建了公共类实用程序,包括为所有测试用例提供服务的 test4_refactoring 函数,例如 salesgrowth_DevInt 。
下面是通用实用程序类代码
import sys
import json, sys, os, argparse, commands, time, string, filecmp
import unittest
class Utility(object):
''' common utility class for common test cases operations'''
def __init__(self):
print "constructor"
pwd = os.getcwd()
print "Current working directlry %s\n" % pwd
global scriptpath
scriptpath = os.path.join(pwd, "src/Runner/")
maxDiff = int(80)
def test4_refactoring(self,STATUS,BASE,ANALYSIS_DIR,OUTPUT,log):
print "common function"
log.write('\n')
if (STATUS.lower() == "completed" or STATUS == "Actor : SUCCESS"):
self.assertEqual(os.stat(OUTPUT + '/tes1.txt').st_size, 0,
'employee count is not matching with master data . Different entries are in test1.txt\n')
but using utility code when i try to execute below statment
self.assertEqual(os.stat(OUTPUT + '/tes1.txt').st_size, 0,
'employee count is not matching with master data . Different entries are in test1.txt\n')
getting below errors

Please let me know if any one has any pointers or suggestion for above issue and what is wrong in above implementation.
