Selenium locate element fails when Chrome in background-CodePudding

This program works fine when you're focused on the window (Chrome), but when you switch to another window like Mozilla, or another app to continue doing your work, the Selenium fails to locate the element.

It should locate the element perfectly fine whether or not I open other apps over it, switch to other windows, and login without issues - that's what I want to accomplish so I can turn it into headless when it isn't giving me this error.

I tried to use driver waits too but to no avail.

The error I get:

selenium.common.exceptions.TimeoutException: Message:

    driver = webdriver.Chrome("C:\Program Files (x86)\chromedriver.exe")

    driver.get("https://twitter.com/i/flow/login")
    sleep(5)

    loginuser = WebDriverWait(driver, 50).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="layers"]/div/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[5]/label/div/div[2]/div/input')))

    return driver

root.mainloop()

This is really annoying as it works sometimes, and sometimes not. I am unable to make this completely automated because of the error that happens when I switch to other processes.

You should use either one of the below locators before jumping to XPath.

ID
name
classname
linkText
partialLinkText
tagName
css selector
xpath

Also, make sure that you should not be using absolute xpath, rather it should be relative xpath.

So, Instead of these

loginuser = WebDriverWait(driver, 50).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="layers"]/div/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[5]/label/div/div[2]/div/input')))
loginuser.send_keys("Username")
sleep(5)
loginuser.send_keys(Keys.RETURN)

loginuser = WebDriverWait(driver, 50).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="layers"]/div/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[3]/div/label/div/div[2]/div[1]/input')))
loginuser.send_keys("Password")
sleep(5)
loginuser.send_keys(Keys.RETURN)

Use this:

wait = WebDriverWait(driver, 30)
loginuser  = wait.until(EC.visibility_of_element_located((By.NAME, "text")))
loginuser.send_keys("Username", Keys.RETURN)
loginPassword = wait.until(EC.visibility_of_element_located((By.NAME, "password")))
loginPassword.send_keys("password here", Keys.RETURN)

CodePudding user response：

Selenium needs to focus on both:

When you bring another window like Mozilla, or another app to the foreground and continue doing your work Selenium looses the focus from the Browser Context. Hence you see the error.
