1 install python
Download Python 3.6
Note: If you have a python3.6 installation package in your hand, skip the step of downloading Python 3.6.
Download python3.6.x, the official website download address is: https://www.python.org/downloads/ , select the appropriate version, click download, enter the download page
Select the executable installer format file on the download page and click to download:
Install Python
Double-click the downloaded python-3.6.4.exe and run the downloaded EXE installation package. Be sure to check Add Python 3.6 to Path, otherwise it is particularly inconvenient to use. Then click Install Now to install.
Run python
After the installation is successful, open the CMD command prompt window and enter python. If something similar to the following appears, the python installation is successful; if it does not appear, it is most likely that the Add Python 3.6 to Path was not checked during the installation process. Please refer to the online python tutorial on adding environment variables.
Open the CMD window and enter:
pip3 install selenium
Selenium will be installed automatically. If no error is reported and the installation is successful, selenium will be installed successfully.
We can verify whether the installation is successful and can be used normally, the verification method:
Open the IELD that comes with python, enter from selenium importwebdriver, and hit enter. If no error is reported, selenium is successfully installed and can be used normally.
After the basic environment is installed, we need an easy-to-use IDE for script writing. Personally recommend pycharm, you can also choose according to your own preferences.
Go to https://www.jetbrains.com/pycharm/download/#section=windows to download pycharm. Professional is a professional version, powerful, but it needs to be charged
Community is a community version, generally the function can be used, and it is free
You can choose according to personal needs.
For specific installation steps and usage methods, please refer to online materials.
4 Install firefox (Firefox) browser and related plug-ins
Why do we need to install the firefox browser? The reason is that the firefox browser has two plug-ins that we need to use:
Selenium IDE: script recording can be achieved
Firebug: Help us locate elements
4.1 install firefox
First, we download firefox, because Selenium IDE cannot support the latest version of firefox browser, so we choose version 54 of firefox, the download link is as follows:
1. http://ftp.mozilla.org/pub/firefox/releases/54.0/win64/zh-CN/
2. Download links for multiple versions of Firefox (very important): http://ftp.mozilla.org/pub/firefox/releases/
The installation process is omitted
Then open the firefox browser, click 
Click Advanced>>Update>>Do not check for updates, in order to prevent firfox from not supporting selenium IDE after automatic update.
4.2 Install Selenium IDE plugin
Open the link with firefox browser:
https://addons.mozilla.org/en-US/firefox/addon/selenium-ide/
The following screen appears, click + Add to Firefox to add the plug-in. After installation, restart the browser to take effect.
After restarting the browser, open Selenium IDE, the following interface appears, then the plug-in is successfully added:
4.3 Add Firebug plugin
Open the link with firefox browser:
https://addons.mozilla.org/zh-CN/firefox/addon/firebug/
The following screen appears, click + Add to Firefox to add the plug-in. After installation, restart the browser to take effect.
After restarting the browser, hit F12 on the keyboard and get the following interface, then the plug-in is added successfully:
5 Install Firefox driver
The above environment is installed, we need to think about such a problem. How do Python and selenium operate the browser?
We need to install the driver of the browser. Different browsers have different drivers. For firefox, we need to open the following link:
https://github.com/mozilla/geckodriver/releases
Choose the appropriate version, because I am a 64-bit windows system, so I choose to download geckodriver-v0.19.1-win64.zip
After the download is complete, unzip geckodriver-v0.19.1-win64.zip to the root record of python. Here, my python installation path is E:\Python\Python36-32\Scripts, so I unzip it to E:\Python\Python36-32\Scripts.
6 Test the entire environment and code
Run the following code, if you can successfully open the Tinglv system page, the environment is set up:
from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.common.keys import Keys from selenium.webdriver.support.ui import Select from selenium.common.exceptions import NoSuchElementException from selenium.common.exceptions import NoAlertPresentException import unittest, time, re class Pyauto0808(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.implicitly_wait(5) self.base_url = "https://www.imguider.com/manager/index.html" self.verificationErrors = [] self.accept_next_alert = True def test_pyauto0808(self): driver = self.driver driver.get(self.base_url + "/manager/index.html") driver.find_element_by_name("username").clear() driver.find_element_by_name("username").send_keys("erha") driver.find_element_by_name("password").clear() driver.find_element_by_name("password").send_keys("erha123") driver.find_element_by_id("login").click() driver.find_element_by_css_selector("span.title").click() driver.find_element_by_css_selector("li.orders > a > span.title").click() driver.find_element_by_link_text("2").click() driver.find_element_by_link_text("3").click() driver.find_element_by_xpath("//div[@id='left']/div/ul/li[8]/a/span").click() driver.find_element_by_link_text(u"优惠券管理").click() driver.find_element_by_id("add-coupon2").click() driver.find_element_by_css_selector("input.layui-layer-input").clear() driver.find_element_by_css_selector("input.layui-layer-input").send_keys("1") driver.find_element_by_link_text(u"确定").click() driver.find_element_by_css_selector("input.layui-layer-input").clear() driver.find_element_by_css_selector("input.layui-layer-input").send_keys("0808") driver.find_element_by_link_text(u"何晨").click() driver.find_element_by_link_text(u"退出登录").click() def is_element_present(self, how, what): try: self.driver.find_element(by=how, value=what) except NoSuchElementException as e: return False return True def is_alert_present(self): try: self.driver.switch_to_alert() except NoAlertPresentException as e: return False return True def close_alert_and_get_its_text(self): try: alert = self.driver.switch_to_alert() alert_text = alert.text if self.accept_next_alert: alert.accept() else: alert.dismiss() return alert_text finally: self.accept_next_alert = True def tearDown(self): self.driver.quit() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main()
