TestReport
测试断言
verbosity=2
0代表得到执行的测试总数和全局结果
1代表得到成功的显示,失败的显示f,错误的显示e,默认的是1
2可以得到详细的信息
1.unittest各个组件
2.unittest测试固件
a.setUp&tearDown
b.setUpClass&tearDownClass
#!/usr/bin/env python
#coding:utf-9
import unittest
import selenium import webdriver
class F2(unittest.TestCase):
@classmethod
def selfUpClass(cls):
cls.driver=webdriver.Chrome()
cls.driver.maximize_window()
cls.driver.implicityly_wait(30)
cls.driver.get("http://www.baidu.com")
@classmethod
def tearDown(cls):
cls.driver.quit()
def test_baidu_new(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)
类方法:会出现找不到元素的问题
改写成:
def test_baidu_new(self):
self.driver.find_element_by_link_text('新闻').click()
self.driver.back()
import unittest
from selenium import webdriver
class F3(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):
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_partial_link_text('图').click()
if __name__ == '__main__':
unittest.main(verbosity=2)
c.程序执行的顺序
d.测试用例的编写方法
写注释,好判断是哪个用例有错误
3.测试执行
4.构建测试套件,就是测试集
a用例按顺序执行(addTest)
#!/usr/bin/env python
#coding:utf-9
import unittest
import selenium import webdriver
class BaiduTest(unittest.TestCase):
@classmethod
def selfUpClass(cls):
cls.driver=webdriver.Chrome()
cls.driver.maximize_window()
cls.driver.implicityly_wait(30)
cls.driver.get("http://www.baidu.com")
@classmethod
def tearDown(cls):
cls.driver.quit()
def test_baidu_new(self):
self.driver.find_element_by_link_text('新闻').click()
self.driver.back()
def test_baidu_map(self):
self.driver.find_element_by_link_text('地图').click()
self.driver.back()
if __name__=="__main__":
suite=unittest.TestSuite()初始化
suite.addTest(BaiduTest('test_baidu_new'))
suite.addTest(BaiduTest('test_baidu_man'))
unittest.TextTestRunner(verbosity=2).run(suite)
执行顺序还是会按照ASCII字母顺序执行,
解决方法就是把用例名用数字编号显示,但是addTest会产生很多相同代码,解决办法就是按类执行
if __name__=="__main__":
suite=unittest.TestSuite()初始化
suite.addTest(BaiduTest)
unittest.TextTestRunner(verbosity=2).run(suite)
b.测试用例执行顺序的详解
c.按测试类执行makeSuite,是个函数
#!/usr/bin/env python
# coding:utf-8
import unittest
from selenium import webdriver
class F7(unittest.TestCase):
def setUp(self):
pass
def tearDown(self):
pass
def test_001(self):
pass
def test_002(self):
pass
if __name__=="__main__":
suite=unittest.TestSuite(unittest.makeSuite(F7))
unittest.TextTestRunner(verbosity=2).run(suite)
d.加载测试类
e按测试模块来执行
if __name__=="__main__":
suite=unittest.TestLoader().loadTestsFromModult('f8.py')
unittest.TextTestRunner(verbosity=2).run(suite)
f优化测试套件
#!/usr/bin/env python
# coding:utf-8
import unittest
from selenium import webdriver
class BaiduLink(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):
self.driver.quit()
pass
def test_001(self):
self.driver.find_element_by_link_text('新闻').click()
def test_002(self):
self.driver.find_element_by_link_text('地图').click()
@staticmethod
def suite():
suite = unittest.TestSuite(unittest.makeSuite(BaiduLink))
return suite
if __name__ =="__main__":
unittest.TextTestRunner(verbosity=2).run(BaiduLink.suite())
5.分离测试固件(模块化的应用)
init.py
#! /usr/bin/env python
codring:utf-8
import unittest
from selenium import webdriver
class Init(unittest.TestCase):
def setUp(self):
self.driver=webdriver.Chrome()
self.driver.maximize_window()
self.driver.implicity_wait(30)
self.driver.get('http://www.baidu.com')
def tearDown(self):
self.driver.quit()
#!/usr/bin/env python
# coding:utf-8
import unittest
from Day10.Init import *
class BaiduSo(Init):
self test_baidu_news(self):
self.driver.find_element_by_id('kw').send_keys('webdriver')
if __name__=="__main__":
unittest.main(verbosity=2)
取消测试用例
@unittest.skip('该功能已经取消,忽略该测试用例的执行')
@unittest.expectedFailure 期望测试用例执行失败
6.测试断言
assertEqual(a,b) 内容一致,类型一致
#coding:utf-8
import unittest
from Day10.init import *
class BaiduLink(Init):
def test_baidu_news(self):
print(self.driver.title,type(self.driver.title))
self.assertEqual(self.driver.title,u'百度一下,你就知道')
if __name__=="__main__":
unittest.main(verbosity=2)
assertTrue(x)
def test_baidu_so(self):
so = self.driver.find_element_by_id('kw')
print so.is_enable()
self.assertTrue(so.is_enabled())
assertIn(a,b)
def test_baidu_title(self):
self.assertIn('百度',self.driver.title)
测试断言注意事项
不正确的使用if
不正确的使用异常
7.批量执行测试用例(discover)
#!/usr/bin/env python
# coding:utf-8
import unittest
import os
def allTests():
suite=unittest.TestLoader.discover(
start_dir = os.path.dirname(__file__),
pattern = 'test_*.py',
top_level_dir=None)
return suite
def run():
unittest.TextTestRunner(verbosity=2).run(allTests())
if __name__=="__main__":
run()
a.获取所有测试用例
b.discover方法的解读
8.生成测试报告
a.python2测试报告的生成
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
b.python3测试报告的生成
!/usr/bin/env python
# coding:utf-8
import unittest
import os
import HTMLTestRunner
def allTests():
suite=unittest.TestLoader.discover(
start_dir = os.path.dirname(__file__),
pattern = 'test_*.py',
top_level_dir=None)
return suite
def run():
fp=os.path.join(os.path.dirname(__file__),'report','testReport.html')
HTMLTestRunner.HTMLRunner(
stream = open(fp,'wb'),
title ='自动化测试报告',
description='自动化测试详细信息').run(allTests())
if __name__=="__main__":
run()
c.测试报告的注意事项
d.新增当前时间
9.unittest的缺陷
10.Coverage的应用
