没有使用机器人框架安装边缘驱动程序

Question

We are using Python robot framework automation. Is it possible to download and install edge driver automatically while script run based on the version passed as parameter?We are using selenium 3.14, robot framework selenium library 4.5.0 and python 3.7

Answer 1

No, that is not possible. Installation of any webdriver must be done before running tests, because it requires to have prepared the environment variable PATH and proper execution permissions for the webdriver.

Answer 2

Is it possible to download and install edge driver automatically while script run based on the version passed as parameter?

Answer- YES

For that you need to install driver manager using - pip install webdriver-manager

Then use the below imports -

from selenium import webdriver
from webdriver_manager.microsoft import EdgeChromiumDriverManager

You can use the python function as keyword in robot framework something like given below. Where 96.0.1054.43 parameter is the version of edge driver. And this function is written in lets say - drivermanager.py file.

def get_chromedriver_path():
    driver_path = EdgeChromiumDriverManager("96.0.1054.43").install()
    print(driver_path)
    return  driver_path

You can import this( drivermanager.py ) library in your testsuite using command - Library drivermanager.py . This function will be treated as keyword when executed.

Testsuite will have testcase as

Open Chrome Browser
    [Documentation]      To create chrome browser instance with specific profile

    ${chromedriver_path}=   drivermanager.Get Chromedriver Path

Here ${chromedriver_path} variable holds the driver path. and the driver stored in the cache.
