unittest测试套件

测试套件就是测试集，测试集是测试用例的集合。

a.按用例顺序执行（addtest）

当addtest与unittest的测试规则冲突时，仍然按照ASCII码的顺序执行。

import unittest
from selenium import webdriver

class Baidu_Test(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Chrome()
        cls.driver.maximize_window()
        cls.driver.implicitly_wait(30)
        cls.driver.get("http://www.baidu.com/")

    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()

    def test_baidu_news(self):
        self.driver.find_element_by_link_text("新闻").click()
        print("aaa")
        self.driver.back()

    def test_baidu_map(self):
        self.driver.find_element_by_link_text("地图").click()
        print("bbb")
        self.driver.back()

if __name__ == "__main__":
    suite = unittest.TestSuite()
    suite.addTest(Baidu_Test("test_baidu_news"))
    suite.addTest(Baidu_Test("test_baidu_map"))
    unittest.TextTestRunner().run(suite)

我是在ubuntu16.04上安装的python3.5.2，运行上述代码后发现并不是先执行的 “test_baidu_news”这个测试用例，依然是先执行“test_baidu_map”再执行“test_baidu_news”

执行结果如下：

Ran 2 tests in 13.497s

OK

Process finished with exit code 0
bbb
aaa

总结：在要按顺序执行时，可以将测试用例设置为test_001这样。

b. 按测试类执行（makesuit）

if __name__ == "__main__":
    suite = unittest.TestSuite(unittest.makeSuite(F2))
    unittest.TextTestRunner().run(suite)

c.按测试模块来执行

import unittest
from selenium import webdriver

class baidu(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.implicitly_wait(30)
        self.driver.get("http://www.baidu.com/")

    def tearDown(self) -> None:
        self.driver.quit()

    def test_baidu_news(self):
        self.driver.find_element_by_link_text("新闻").click()

    def test_baidu_map(self):
        self.driver.find_element_by_link_text("地图").click()

class baidu_search(unittest.TestCase):
    def setUp(self) -> None:
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.implicitly_wait(30)
        self.driver.get("http://www.baidu.com/")

    def tearDown(self) -> None:
        self.driver.quit()

    def test_badu_search(self):
        self.driver.find_element_by_id("kw").send_keys("english")
        self.driver.find_element_by_id("su").click()

if __name__ == "__main__":
    suite = unittest.TestLoader().loadTestsFromModule("unittest_case4.py")
    unittest.TextTestRunner().run(suite)　　

d.优化测试套件

第一种：

import unittest
from selenium import webdriver

class baidu(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.implicitly_wait(30)
        self.driver.get("http://www.baidu.com/")

    def tearDown(self) -> None:
        self.driver.quit()

    def test_baidu_news(self):
        self.driver.find_element_by_link_text("新闻").click()

    def test_baidu_map(self):
        self.driver.find_element_by_link_text("地图").click()

    @staticmethod
    def suite():
        suite = unittest.TestSuite(unittest.makeSuite(baidu))
        return suite

if __name__ == "__main__":
     unittest.TextTestRunner().run(baidu.suite())

第二种：把固定的语句分离出来

测试用例模块：

from test import * #倒入自己编写的模块
import unittest

class baidu(Info):   #继承
    def test_baidu_news(self):
        self.driver.find_element_by_link_text("新闻").click()

    def test_baidu_map(self):
        self.driver.find_element_by_link_text("地图").click()

if __name__ == "__main__":
    unittest.main(verbosity=2)

　固定的套件模块（test.py）：

import unittest
from selenium import webdriver
class Info(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.implicitly_wait(30)
        self.driver.get("http://www.baidu.com/")
    def tearDown(self) -> None:
        self.driver.quit()
