数据驱动测试。使用 Selenium Python 从 .json 或 .yaml 文件读取参数
Data driven tests. reading parameters from a .json or .yaml file using Selenium Python
我使用 Selenium 和 Python 创建了一个框架。
到目前为止，我的数据驱动框架由 2 个文件组成：
第一个文件- Setup.py 包含 class Actions()
包含我将使用的所有可能的功能
在我的框架中，例如：
def __init__():
def setup():
def tearDown():
def click():
def sendKeys():
我的 click 和 sendKeys 函数至少有 2 个参数。
他们采用第一个参数，例如我们 :id_for_element，
xp_for_element，或 css_for_element，切词直到
他们得到第一个两个字符并通过其中一个找到元素
id、xp 或任何其他方式。然后他们使用第二个参数来
指定一个元素的值，第三个参数指定
send_keys() 函数的值。所有这些功能
现在正在工作，但到目前为止，我的测试文件中的值是硬编码的。

相反，我试图从另一个传递参数值
数据驱动测试最佳实践所描述的文件
框架。我的下一步是创建一个 data.json 文件
我将在下面使用映射出 DOM 的所有元素
格式："id_login_button":"some id value", "xp_input_field":"some
xp 值”等。请有人帮我弄清楚
如何实现这个技术？
如果您想使用 json 作为您的 uiRepo，这是简单的方法。
sample.json:
{
"id_of_yahoo_logo":"uh-logo",
"xp_of_signIn_button":"//*[@id='uh-signin']",
"id_username_login_inp_field":"New York",
"id_of_submit_button":"login-signin"
}
test.py
# you have to just specify the name as shown below
action.click('xp_of_signIn_button)
Actions.py中的读取值：
import json
#parse json
with open('sample.json') as f:
uiRepo = json.load(f)
# update the generic methods to get the property form json
print(uiRepo['id_of_yahoo_logo'])
