Python单元测试框架unittest

  • 在unittest.main()中加 verbosity 参数可以控制输出的错误报告的详细程度,默认是 1,如果设为 0,则不输出每一用例的执行结果,如果设为 2,则输出详细的执行结果;
  • 测试用例忽略
  @unittest,skip(reason):无条件跳过
  @unittest.skipIf(condition, reason):当condition为True时跳过
  @unittest.skipUnless(condition, reason):当condition为False时跳过 
  • 控制用例的执行顺序
方法1: 通过TestSuite按照顺序添加想要执行的方法
suite = unittest.TestSuite()
testcases = [TestClass('method_c'), TestClass('method_b'),TestClass('method_a')]
suite.addTests(testcases)
unittest.TextTestRunner(verbosity=2).run(suite)

    方法2:顺应testunit的执行顺序,就是通过控制方法名字来实现

test_a_casename  test_b_casename  test_c_casename 
  • 将结果输出到文件中   
suite = unittest.TestSuite()
testcases = [TestClass('method_c'), TestClass('method_b'),TestClass('method_a')]
suite.addTests(testcases)
with open('report.txt', 'a') as f:
    runner = unittest.TextTestRunner(stream=f, verbosity=2)
    runner.run(suite)

执行此文件,可以看到,在同目录下生成了report.txt

  • setUp和tearDown在每次执行case前后都执行了一次
  如果想要在所有case执行之前准备一次环境,并在所有case执行结束之后再清理环境,我们可以用 setUpClass() 与
       tearDownClass():
import unittest
class Test(unittest.TestCase):    
    @classmethod
    def setUpClass(cls):
        print "This setUpClass() method only called once."
    @classmethod
    def tearDownClass(cls):
        print "This tearDownClass() method only called once too."      
    def test_a(self):
        print 'aaaaaaaaaaa'
    def test_b(self):
        print 'bbbbbbbbbb'
if __name__ == '__main__':
    unittest.main()

运行结果:

This setUpClass() method only called once.
aaaaaaaaaaa
.bbbbbbbbbb
.This tearDownClass() method only called once too.

  • 生成html报告
我们下载HTMLTestRunner.py,并放到当前目录下,或者你的 Python的Lib目录下,就可以导入运行了。

with open('report.html', 'w') as f:
        runner =HTMLTestRunner(stream=f, title='demotest',description= 'htmlrunner', verbosity=2)
        runner.run(suite)
