单击 Selenium 中的链接：find_element_by_link_text 不起作用

Question

I am going to click on a link via selenium but it doesn't work when I applied find_element_by_link_text as a following: (URL: https://healthunlocked.com/positivewellbeing )

HTML Code

<a class href="/positivewellbeing/posts">Posts</a>

Selenium Code:

driver.find_element_by_link_text('Posts').click()

I don't have any error, but this code line didn't run or work

Answer 1

Try to add .element_to_be_clickable before clicking:

wait = WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable((By.LINK_TEXT, 'Posts'))).click()

#update here
wait.until(EC.url_to_be('https://healthunlocked.com/positivewellbeing/posts'))
print(driver.current_url)

The following imports:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

Based on your comments, if you want to wait for the url to change to the way you want, please use EC.url_to_be . Because time.sleep (...) is a bad way, please see the above updated code.

See more about expected_conditions here:

Answer 2

If you are using.Net you can try to use Coypu library in your project:

https://github.com/featurist/coypu https://www.nuget.org/packages/Coypu/

Coypu it's a wrapper that will save you from retries, sleeps (waits).

It supports browser automation in.Net to help make tests readable, robust, fast to write and less tied to a UI. If your tests are littered with sleeps, retries, complex XPath expressions and IDs then Coypu might help.

Coypu is on Nuget:

PM> Install-Package Coypu

I work in a project where we have around 3k automated tests developed with C# and Selenium and my life would be kind of miserable without Coypu.

Your code will look the same when using Coypu but the sleep will be automatically handled by the library, it's transparent to the user:

Browser.FindXPath("//*[contains(text(), 'Posts')]").Click();

Browser.FindIdEndingWith("Posts").Click();
