After reading this article, you will learn how to build a basic Selenium automation environment on Windows.

1. The system environment used this time is the latest Windows 10 17134 system.

two。 The Python version used this time is 3.4.4. The reason for using this version is that the XP system will not be supported after 3.5, but I need a XP environment, so I have been using version 3.4, Python download address: https://www.python.org/downloads/

3. The Selenium version used this time is the latest 3.13. If only one version of Python is installed on your computer, you can use the command line directly:

Python-m pip install selenium

For installation.

If you have multiple versions of Python installed on your computer and renamed using the "" I mentioned earlier, please use the corresponding command line version, such as:

Python34-m pip install selenium

For installation.

If you fail to install this command, you can try it a few more times. After all, what you link to is a foreign site, you know.

Of course, you can also download the whl file from the official website to install it. The command line for installing the whl file is:

Python-m pip install selenium-xxx.whl

Download address of whl file: https://pypi.org/project/selenium/#files

The official installation instructions can be found here: http://selenium-python.readthedocs.io/installation.html#downloading-python-bindings-for-selenium

4. The browser version used this time is the latest Google Chrome 68.0.3440.84 (official version) (64-bit), which can be downloaded by FQ or through "360 Software Housekeeping".

Official download address: https://www.google.com/chrome/

5. The ChromeDriver version used this time is the latest 2.41. Please note that different ChromeDriver versions support different Chrome versions. It is recommended that both of them be updated to the latest to avoid repeated trampling.

If you are not using Chrome, please install the corresponding Driver. All Driver addresses can be found here: http://selenium-python.readthedocs.io/installation.html#drivers

The download address of ChromeDriver is: https://sites.google.com/a/chromium.org/chromedriver/downloads

The Driver of the same browser also distinguishes different system versions. For example, the file of ChromeDriver on Windows platform is chromedriver_win32.zip.

6. The downloaded ChromeDriver is a zip package. In the Windows version, there is a chromedriver.exe. Please note:

The decompressed chromedriver.exe full path needs to be added to the system environment variable path.

After path modification, the command line tool needs to be restarted to take effect.

You can check whether the addition is successful by typing the command path on the command line

Another trick is to drop chromedriver.exe directly into the scripts directory under the python installation directory. If you are not mistaken, this directory has previously added environment variables, so there is no need to modify the environment variables.

7. If you strictly follow the above steps, the basic environment should be ready. Let's start writing the first script according to the official tutorial:

#-*-coding: utf-8-*-"selenium webdriver test demo" import timefrom selenium import webdriverdef test (): driver = webdriver.Chrome () driver.get ('http://www.google.com/xhtml') time.sleep (2) # Let the user actually see something! Search_box = driver.find_element_by_name ('q') search_box.send_keys ('ChromeDriver') search_box.submit () time.sleep (5) # Let the user actually see something! Driver.quit () if _ _ name__ = ='_ _ main__': test ()

8. The effect after running is as follows. If you see the prompt "Crhome is under the control of automated testing software", the environment is prepared correctly.

9. At this point, the Selenium automation environment is successfully built, and we can carry out the journey of selenuim automation according to webdriver api (http://selenium-python.readthedocs.io/api.html)).
