前言
当测试用例写完后,有些模块有改动时候,会影响到部分用例的执行,这个时候我们希望暂时跳过这些用例。
或者前面某个功能运行失败了,后面的几个用例是依赖于这个功能的用例,如果第一步就失败了,后面的用例也就没必要去执行了,直接跳过就行,节省用例执行时间。
一、skip装饰器
skip装饰器一共有四个
@
unittest.
skip
(reason)
-
Unconditionally skip the decorated test. reason should describe why the test is being skipped.
翻译:无条件跳过用例,reason是说明原因
@
unittest.
skipIf
(condition, reason)-
Skip the decorated test if condition is true.
翻译:condition为true的时候跳过
@
unittest.
skipUnless
(condition, reason)-
Skip the decorated test unless condition is true.
翻译:condition为False的时候跳过
@
unittest.
expectedFailure
-
Mark the test as an expected failure. If the test fails when run, the test is not counted as a failure.
翻译:断言的时候跳过()
二、skip案例
运行结果:
测试1
测试4
.ssx
----------------------------------------------------------------------
Ran 4 tests in 0.003s
OK (skipped=2, expected failures=1)
三、跳过整个测试类
四、参考代码:
# coding:utf-8
import unittest
class Test(unittest.TestCase):
@unittest.skip(u"无条件跳过此用例")
def test_1(self):
print "测试1"
@unittest.skipIf(True, u"为True的时候跳过")
def test_2(self):
print "测试2"
@unittest.skipUnless(False, u"为False的时候跳过")
def test_3(self):
print "测试3"
@unittest.expectedFailure
def test_4(self):
print "测试4"
self.assertEqual(2, 4, msg=u"判断相等")
if __name__ == "__main__":
unittest.main()
