2、处理excel表的测试数据

十、使用邮件接收测试结果

八、测试套件TestSuite和测试运行器TestRunner

测试套件（Test Suite）是用于组织和管理多个测试用例（Test Case）的容器，它允许你将不同模块中多个测试用例集合在一起并一起执行。
测试运行器（TestRunner），用于执行 TestSuite 中的所有测试用例，并将结果以文本的形式输出到控制台。
TestSuite 和 TextTestRunner 通常是配合使用的。TestSuite 组织和管理测试用例，TextTestRunner 执行这些测试用例并输出测试结果。

1、基本概念

测试用例（Test Case）是指单个的测试方法，它验证了某个功能或行为是否符合预期。
测试套件（Test Suite）是由多个测试用例组成的集合。它可以包含多个测试用例，也可以包含其他测试套件，从而形成一个嵌套的结构。
测试运行器（TestRunner）：TextTestRunner 会接收一个 TestSuite 对象并执行其中的所有测试用例。它会在控制台中输出详细的测试结果，包括每个测试用例的执行情况（通过、失败、错误等）。另外通过自定义 TestResult 类，TextTestRunner 也可以支持更详细或不同格式的输出。

2、创建和使用测试套件

在 unittest 中，测试套件主要通过 unittest.TestSuite 类来创建。你可以通过以下两种方式来创建和执行测试套件：①手动将测试用例添加到测试套件；②自动发现并添加测试用例。

3、自动发现测试用例、创建测试套件、运行测试

unittest 提供了一个 discover() 方法，可以自动发现符合特定命名规则的测试用例并将它们组织成一个测试套件。它会递归地查找指定目录下的所有测试模块并将它们自动加载到测试套件中。

在当前项目中创建main.py文件

import unittest# 自动发现当前目录下的所有测试模块并运行
suite =unittest.TestSuite()
case = unittest.defaultTestLoader.discover(start_dir=".",pattern="test*.py")suite.addTest(case)# 创建测试运行器，执行测试套件，是固定的使用方法
runner = unittest.TextTestRunner()
runner.run(suite)

discover() 方法：unittest.defaultTestLoader.discover() 会从指定的 start_dir 目录开始递归查找所有符合 pattern 模式的测试文件。默认情况下，文件名应该以 test_ 开头，后面跟 .py 后缀。
执行测试套件：通过 unittest.TextTestRunner() 执行自动发现的测试套件。

4、生成html的测试报告：HTMLTestRunner

unittest自带的测试报告是文本格式的，可读性不强，所以一般使用第三方模块来生成测试报告。

HTMLTestRunner 是 Python unittest 框架的一个第三方扩展，用于将测试结果以 HTML 格式输出，而不是标准的文本输出。它提供了一个漂亮且直观的报告，适用于需要以网页形式查看测试结果的场景。

1️⃣导入HTMLTestRunner模块

HTMLTestRunner模块下载不能通过pip安装，需要新建新建 HTMLTestRunner.py 文件，将网页内容复制到文件中即可。

"""
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 unittestimport 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 filefp = 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 optionsrunner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'# run the testrunner.run(my_test_suite)------------------------------------------------------------------------

2️⃣运行测试用例并生成html文件

HTMLTestRunner主要有三个参数：

stream：测试报告写入文件的存储位置。
title：测试报告的标题。
description：测试报告的描述。

import unittest
from HTMLTestRunner import HTMLTestRunner
# 自动发现当前目录下的所有测试模块并运行
suite =unittest.TestSuite()
case = unittest.defaultTestLoader.discover(start_dir=".",pattern="test*.py")suite.addTest(case)# 创建测试运行器，执行测试套件，是固定的使用方法
with open("测试报告.html","wb") as f:runner = HTMLTestRunner(stream=f,title="测试报告",description="这是项目的描述。。。")runner.run(suite)

九、unittest测试框架的设计与实现

1、对项目重构

新建文件夹reports专门存放测试报告
新建文件夹data专门存放测试数据
新建文件夹case专门存放测试用例
新建文件夹utils专门第三方的包等工具
把utils中的HTMLTestRunner.py变成一个包：在utils文件夹中新建一个__init__.py 的空文件。这个文件告诉 Python 该目录应该被视为一个包。
修改代码中start_dir的值.为case，即case = unittest.defaultTestLoader.discover(start_dir="case",pattern="test*.py")
修改代码中测试报告的路径为：with open("reports/测试报告.html", "wb") as f:
改造测试报告的名字，以便可以保存历史报告：首先引入time模块，获取现在的时间（年-月-日-时-分-秒），设置reportpath变量，替换测试报告的存放路径。

修改后的main.py文件

import unittest
import time
from utils.HTMLTestRunner import HTMLTestRunner
# 自动发现当前目录下的所有测试模块并运行
suite =unittest.TestSuite()
case = unittest.defaultTestLoader.discover(start_dir="case",pattern="test*.py")suite.addTest(case)now = time.strftime("%Y-%m-%d-%H-%M-%S")
reportPath = f"reports/测试报告-{now}.html"# 创建测试运行器，执行测试套件，是固定的使用方法
with open(reportPath, "wb") as f:runner = HTMLTestRunner(stream=f,title="测试报告",description="这是项目的描述。。。")runner.run(suite)

2、处理excel表的测试数据

下载第三方的包openpyxl

pip install openpyxl -i https://pypi.tuna.tsinghua.edu.cn/simple

在utils中封装一个excelFunc.py的包，专门用来读excel表的数据

from openpyxl import load_workbookdef readExcleData(fileName,sheetName,coor):"""读取excle的数据"""excle = load_workbook(fileName)sheet = excle[sheetName]min_row = coor.get("min_row")max_row = coor.get("max_row")min_col = coor.get("min_col")max_col = coor.get("max_col")dataList = sheet.iter_rows(min_row,max_row,min_col,max_col)result = []for row in dataList:rows = []for i in row:rows.append(i.value)result.append(rows)return resultif __name__ == "__main__":coor = {"min_row":1, # 根据需求修改数字"max_row":1,"min_col":1,"max_col":1}data = readExcleData("../data/测试数据.xlsx","Sheet1",coor)print(data)

如果excel表中是：

读取2到4行，1到4列的结果

这样在做数据驱动测试的时候就可以使用ddt来处理测试数据了

十、使用邮件接收测试结果

准备工作：在邮箱的设置中开启amtp功能，然后生成一个授权码

在utils中封装一个emailFunc.py的包，实现发送邮件的功能

import smtplib
from email.mime.application import MIMEApplication
from email.mime.text import MIMEText

增加main.py的内容：添加了emailFunc包，以及最后一行调用endEmail代码

import unittest
import time
from utils.HTMLTestRunner import HTMLTestRunner
from utils.emailFunc import sendEmail
# 自动发现当前目录下的所有测试模块并运行
suite =unittest.TestSuite()
case = unittest.defaultTestLoader.discover(start_dir="case",pattern="test*.py")suite.addTest(case)now = time.strftime("%Y-%m-%d-%H-%M-%S")
reportPath = f"reports/测试报告-{now}.html"# 创建测试运行器，执行测试套件，是固定的使用方法
with open(reportPath, "wb") as f:runner = HTMLTestRunner(stream=f,title="测试报告",description="这是项目的描述。。。")runner.run(suite)# 测试报告以邮件发送给xxxxxxx@qq.com
sendEmail('xxxxxxx@qq.com',reportPath)

八、测试套件TestSuite和测试运行器TestRunner

1、基本概念

2、创建和使用测试套件

3、 自动发现测试用例、创建测试套件、运行测试

4、生成html的测试报告：HTMLTestRunner

1️⃣导入HTMLTestRunner模块

2️⃣运行测试用例并生成html文件

九、unittest测试框架的设计与实现

1、对项目重构

2、处理excel表的测试数据

十、使用邮件接收测试结果
