unittest学习3：用例执行

unittest执行用例方法：

1、单个py文件

if __name__ == "__main__":
    unittest.main()

2、多个py文件，引用测试用例，使用测试套件，执行所加载到套件中用例

import unittest
from test_case.test_study1 import Test_Study1
from test_case.test_study2_skip import Test_Study2

# 实例化测试套件及加载用例
suit = unittest.TestSuite()
suit.addTest(Test_Study1('test_case1'))
suit.addTest(Test_Study1('test_case2'))
suit.addTest(Test_Study2('test_case4'))

# 实例化runner及执行套件中用例
runner = unittest.TextTestRunner()
runner.run(suit)

3、使用discover，批量执行

　　case_dir：要执行的用例目录

　　pattern：匹配测试用例规则，test*.py即，匹配所有test开头的脚本

import unittest
import os


case_path = os.path.join(os.path.dirname(os.getcwd()), "test_case")
discover = unittest.defaultTestLoader.discover(case_path, pattern="test*.py", )

runner = unittest.TextTestRunner()
runner.run(discover)

4、加载测试类

import unittest
from test_case.test_study1 import Test_Study1
from test_case.test_study2_skip import Test_Study2

suite1 = unittest.TestLoader().loadTestsFromTestCase(Test_Study1)
suite2 = unittest.TestLoader().loadTestsFromTestCase(Test_Study2)
suite = unittest.TestSuite([suite1, suite2])

runner = unittest.TextTestRunner()
runner.run(suite)
