but I am trying to write a unit test for my website that runs through all the links and returns an A ok or no go if the site is working. But I am having trouble with the program it's not able to constantly click the link in the site navigation bar. I've tried multiple waits implicit. Explicit, expected condition but the page loads and half the time it will click the link and go to that part of the site and the other half the program just stops and nothing is clicked.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver import ActionChains

PATH = "C:\Program Files (x86)\chromedriver.exe"

drive = webdriver.Chrome(PATH)
drive.get("https://www.blackhempfamily.com/")

wait = WebDriverWait(drive, 10)
link = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Why Black Hemp?")))
link.click()

Would be a better tag to use.

wait.until(EC.element_to_be_clickable((By.XPATH, "//p[text()='Why Black Hemp?']")))

Try it with xpath instead, and with element to be located (not clickable), as it is a paragraph. This worked for me:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver import ActionChains

PATH = "C:\Program Files (x86)\chromedriver.exe"

drive = webdriver.Chrome(PATH)
drive.get("https://www.blackhempfamily.com/")

linkWait = EC.element_to_be_located((By.XPATH, "//div/p[contains(., 'Why Black Hemp?')]"))
WebDriverWait(drive, 10).until(linkWait)
link = drive.find_element_by_xpath("//div/p[contains(., 'Why Black Hemp?')]")
link.click()

The element you're searching for is not a link. It's a paragraph (p). I added a sleep call to give the page more load time.

Try this code:

time.sleep(3)
wait = WebDriverWait(drive, 10)
#link = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Why Black Hemp?")))
link = drive.find_element_by_xpath('//*[@id="idh09fqo2label"]')
link.click()

neither of the lines worked still I get to the site home page then like the whole page kinda blinks and then the program stops doing nothing.
I tested a few more times. It did miss once. Adding sleep seemed to solve the problem.
Using sleep() is not a good practice and why are you using find_element_by_xpath() to find an ID? Use find_element_by_id() instead. Your current code doesn't even use the wait you instantiated, why have that code in there?

So, it took a while ... but, I think that I was able to figure this out. The actions that you need to do are:

  1. Click "Why Black Hemp?"
  2. Wait until the page stops scrolling
  3. Scroll to the top of the page
  4. Wait until the page stops scrolling
  5. **Attempt to scroll down so you can get the nav bar to display
  6. Repeat until your heart is content / Test Passes with "A-OK"

In order for this to be achieved, you need to have the following imports

from selenium import webdriver
from selenium.webdriver.chrome.webdriver import WebDriver as ChromeWebDriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as DriverWait
from selenium.webdriver.support import expected_conditions as DriverConditions
from selenium.common.exceptions import WebDriverException
import time

Step 1 - Click your "Why Black Hemp?" nav bar element

chrome_driver.find_element(By.XPATH, "//nav[contains(@id, 'navContainer')]//p[text()='Why Black Hemp?']/../../..").click()

Step 2 - Check to see if our page is still scrolling

# Checks to see if our page is still scrolling
    while is_same_position == False:
        windowPosition1 = chrome_driver.execute_script("return document.body.scrollHeight;")
        time.sleep(2)
        windowPosition2 = chrome_driver.execute_script("return document.body.scrollHeight;")
        if(windowPosition1 == windowPosition2):
            is_same_position = True
            final_window_position = windowPosition1

Step 3 - Scroll to the top of the page

chrome_driver.execute_script("window.scrollTo(0, {0})".format((0 - final_window_position)))

Step 4 - Check to see if our page is still scrolling

# Checks to see if our page is still scrolling
    while is_same_position == False:
        windowPosition1 = chrome_driver.execute_script("return document.body.scrollHeight;")
        time.sleep(2)
        windowPosition2 = chrome_driver.execute_script("return document.body.scrollHeight;")
        if(windowPosition1 == windowPosition2):
            is_same_position = True

Step 5 - Attempt to scroll down until our header tag does not have the style of visibility: hidden

# Scrolls down until our nav bar is displayed
    for scrollNum in range(10):
        chrome_driver.execute_script("window.scrollTo(0, {0})".format(scrollNum * 100 + 200))
        time.sleep(2)
        if is_displayed(chrome_driver, "//header[contains(@style, 'visibility: hidden')]") == False:
            break

Step 6 - Repeat until your heart is content

Thank you very much for this I'm building a test program for all the links and elements in blackhempfamily.com but this definitely helped me out. You put me on to some more parts of python I should investigate. Thank you again.
No problem. @cartier_5 . I would appreciate an upvote if it helped ;) #ThirstyForTheUpVote
