Basic Selenium Setup

Basic Selenium Setup Guide

Selenium is an open-source, widely used software testing framework primarily used for automating web browsers. It allows testers and developers to write automation on the frontend for QA testing and more.

Install and Setup

1. Install selenium with pip3.

   pip3 install selenium
   

2. Check Chrome version, open browser and type:

   chrome://version/
   

3. Install the driver that matches your Chrome’s version.

4. Now you can start using selenium. Try the following code to use Selenium to log into Tradingview.

   from selenium import webdriver
   from selenium.webdriver.chrome.service import Service
   from selenium.webdriver.chrome.options import Options
   from selenium.webdriver.common.by import By
   from selenium.webdriver.support.ui import WebDriverWait
   from selenium.webdriver.support import expected_conditions as EC
   #
   service = Service(r'/Users/nicehost/Documents/Local_Files/Browser_Drivers/chromedriver')
   chrome_options = Options()
   #chrome_options.add_argument('--no-sandbox')
   #chrome_options.add_argument('--headless')
   chrome_options.add_argument('--disable-deb-shm-usage')
   driver = webdriver.Chrome(service=service, options=chrome_options)
   driver.maximize_window()
   #
   longInfo = ["my-user-name", "my-pass-word"]
   driver.get("https://www.tradingview.com/#signin")
   wait=WebDriverWait(driver, 10)
   wait.until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Email']"))).click()
   wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "[name='username']"))).send_keys(longInfo[0])
   wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "[name='password']"))).send_keys(longInfo[1])
   wait.until(EC.element_to_be_clickable((By.XPATH, "//button[.//span[contains(., 'Sign in')]]"))).click()
