Python自动化测试系列[v1.0.0][多种数据驱动实现附源码]-编程知识

前情提要

请确保已经熟练掌握元素定位的常用方法及基本支持，请参考Python自动化测试系列[v1.0.0][元素定位]

数据驱动测试是自动化测试中一种重要的设计模式，这种设计模式可以将测试数据和测试代码分开，实现数据与代码解耦，与此同时还能够实现一次任务中使用不同的数据来执行执行相同的测试脚本，因此它会使得我们的代码层次结构清晰，容易维护，并且大大降低了代码量

数据驱动是自动化测试中非常常见的一种设计模式，应用的场景非常多，无论是在Web自动化还是在接口自动化、单元测试，亦或是在数据分析应用领域的测试上都会得到非常广泛的使用，常见的比如Web自动化的登录功能、一些录入类的功能，再比如接口入参、单元测试的入参，甚至在数据类应用的大量数据输入及结果比较上

使用Excel存储测试输入数据

数据文件

假如我们有如下一组数据存储在Excel里

序号	检索词	期望结果
1	北京	北京
2	上海	上海
3	广州	广州

获取测试数据方法

通过python的openpyxl模块解析Excel文件，并获取数据

安装openpyxl

C:\Users\Administrator>pip install openpyxl
Collecting openpyxlDownloading openpyxl-3.0.3.tar.gz (172 kB)|████████████████████████████████| 172 kB 384 kB/s

方法封装

# encoding = utf-8
from openpyxl import load_workbookclass ParseExcel(object):def __init__(self, excelPath, sheetName):self.wb = load_workbook(excelPath)#  self.sheet = self.lwb.get_sheet_by_name(sheetName)self.sheet = self.wb[sheetName]self.maxRowNum = self.sheet.max_rowdef getDatasFromSheet(self):dataList = []for line in list(self.sheet.rows)[1:]:tmpList = []tmpList.append(line[1].value)tmpList.append(line[2].value)dataList.append(tmpList)return dataListif __name__ == '__main__':excelPath = u'D:\\Programs\\Python\\PythonUnittest\\TestData\\测试数据.xlsx'sheetName = u'搜索数据表'pe = ParseExcel(excelPath, sheetName)for i in pe.getDatasFromSheet():print(i[0], i[1])

封装了getDatasFromSheet方法，该方法将解析Excel，并将数据存到List中去，后续的测试代码调用的实际上是从List里边获取数据

使用Parameterize模块组织数据集作为测试输入数据

安装PARAMETERIZE

使用JSON存储测试输入数据[字典]

除了在json文件中放置List类型的数据，还可以放置Dict类型的数据，在PO项目的TestData路径下新建一个文件，并命名为login.json，然后在文件中写入如下测试数据。

{"test_login_01": {"username":"","password":"davieyang","assert_text": "请输入帐号"},"test_login_02": {"username":"davieyang","password":"","assert_text": "请输入密码"},"test_login_03":{"username":"error","password":"error","assert_text": "帐号或密码错误"}
