Fedora23 install and use web automation testing tools selenium and fedora23selenium

1. pip install selenium requires root permission

2. Run openchrome. py:

from selenium import webdriverfrom selenium.common.exceptions import NoSuchElementExceptionfrom selenium.webdriver.common.keys import Keysimport timebrowser = webdriver.Chrome() # Get local session of Chromebrowser.get("http://www.bing.com") # Load pageassert "Bing" in browser.titleelem = browser.find_element_by_name("q") # Find the query boxelem.send_keys("seleniumhq" + Keys.RETURN)time.sleep(0.2) # Let the page load, will be added to the APItry:    browser.find_element_by_xpath("//a[contains(@href,'http://docs.seleniumhq.org/')]")except NoSuchElementException:    assert 0, "can't find seleniumhq"browser.close()              

Error:

FileNotFoundError: [Errno 2] No such file or directory: 'chromedriver'

Selenium. common. exceptions. WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Use the prompt link to download chromedriver. Download and unzip it.

Add the PATH of chromedriver to the path variable: vim ~ /. Bash_profile

PATH=$PATH:$HOME/.local/bin:$HOME/bin:/home/codc/.browserdriver/chromedriverexport PATH

Append/home/codc/. browserdriver/chromedriver to the end of PATH.

Source ~ /. Bash_profile make the path take effect

Run python openchrome. py again, and an error is returned:

Selenium. common. exceptions. WebDriverException: Message: unknown error: Chrome version must be> = 55.0.2883.0
(Driver info: chromedriver = 2.28.455506 (18f6627e265f442aeec9b6661a49fe819aeeea1f), platform = Linux 4.2.3-300. fc23.x86 _ 64 x86_64)

The reason is that the downloaded chromedirver is the latest version, and the chrome version is older, and chrome is updated: dnf update google-chrome

Google-chrome needs to configure the source repository used by dnf chrome, Which is downloaded from rpmfusion free by default.

Note: The message geckodriver is displayed in firefox.
