Python自动化测试框架——生成测试报告

Posted 2020-10-20 忘羡恒久远，代码永流传

小编实测，在自动化执行测试用例的过程中，生成简易测试报告

如何才能让用例自动运行完之后，生成一张直观可看易懂的测试报告呢？

小编使用的是unittest的一个扩展HTMLTestRunner

• 环境准备

使用之前，我们需要下载HTMLTestRunner.py文件

点击HTMLTestRunner后进入的是一个写满代码的网页，小编推荐操作：右键 --> 另存为，文件名称千万不要改

python3使用上述HTMLTestRunner可能会报错，可以替换如下文件

"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    import unittest
    import HTMLTestRunner

    ... define your tests ...

    if __name__ == \'__main__\':
        HTMLTestRunner.main()


For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest\'s TextTestRunner. E.g.

    # output to a file
    fp = file(\'my_report.html\', \'wb\')
    runner = HTMLTestRunner.HTMLTestRunner(
                stream=fp,
                title=\'My unit test\',
                description=\'This demonstrates the report output by HTMLTestRunner.\'
                )

    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = \'<link rel="stylesheet" href="my_stylesheet.css" type="text/css">\'

    # run the test
    runner.run(my_test_suite)

HTMLTestRunner

• 使用

接下来，小编将以登录网易邮箱为例，生成一份最基础的测试报告。小伙伴们copy走代码验证时一定记得修改账号密码哦。

目录结构如下：

 将HTMLTestRunner.py文件存放到package包下，将test_login.py存放到testcase目录下，用于编写测试用例，建立testreport包，用于存放测试报告，在email目录下建立run_test.py，用于执行测试

HTMLTestRunner的使用方法在代码注释中介绍和解释

【test_login.py】

from selenium import webdriver
import unittest,time

class Login(unittest.TestCase):
    def setUp(self):
        #打开百度，搜索“163网易邮箱”，登录
        driver=webdriver.Firefox()
        driver.implicitly_wait(5)
        self.driver=driver
        driver.get("https://www.baidu.com/")

        driver.find_element_by_id("kw").send_keys("163邮箱登录")
        driver.find_element_by_id("su").click()

        name = driver.find_element_by_id("op_email3_username")
        password = driver.find_element_by_class_name("op_email3_password")
        login = driver.find_element_by_css_selector(".c-btn")

        #如下操作可以使setUp中的变量被其他模块调用
        self.name=name
        self.password=password
        self.login=login

    def tearDown(self):
        self.driver.quit()

    def switch_window(self):
        #切换窗口
        for handle in self.driver.window_handles:
            self.driver.switch_to.window(handle)
            #j增加等待时间，可以提高测试用例执行的健壮性
            time.sleep(2)
        time.sleep(3)

    #成功登录
    def test_right_login(self):
        #账号密码自行填写
        self.name.send_keys("xxx")
        self.password.send_keys("xxx")
        self.login.click()

        self.switch_window()
        #t通过新窗口的title验证用例是否通过
        self.assertEqual(self.driver.title,"网易邮箱6.0版","登录失败")
