[英]How to get rid of the hardcoded sleep()?
def textfield(boxid,textadded):
project = driver.find_element_by_id(boxid)
project.send_keys(textadded)
sleep(3)
def dropdown(dropdownid, dropdownvalue):
select = Select(driver.find_element_by_id(dropdownid))
select.select_by_visible_text(dropdownvalue)
sleep(5)
These 2 functions are functional however i'm using sleep()
which is a bad practice since some my drop-downs and text fields will take longer than others to fill so i have to put the longest sleep value not to get errors, how can i fix these 2 functions using wait. 这两个函数都起作用,但是我正在使用
sleep()
,这是一个不好的做法,因为某些下拉列表和文本字段需要比其他字段更长的时间来填充,因此我必须使用最长的睡眠值才能避免出错,如何我使用等待修复了这两个功能。
You can explicitly wait for the element. 您可以显式等待该元素。 Read more about waits here .
在此处阅读有关等待的更多信息。 Please note that this is not the official documentation.
请注意,这不是官方文档。
#.....
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait

select=WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID ,dropdownid)))

As you are invoking send_keys()
on the WebElement project , ideally you should invoke WebDriverWait with EC as element_to_be_clickable
, so you have to: 在WebElement 项目上调用
send_keys()
时,理想情况下,应使用EC作为element_to_be_clickable
调用WebDriverWait ,因此您必须:
Replace: 更换:
def textfield(boxid,textadded): project = driver.find_element_by_id(boxid) project.send_keys(textadded) sleep(3)
with: 与:
def textfield(boxid,textadded): WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "boxid"))).send_keys(textadded)
As the drop-down take longer to fill so you should invoke WebDriverWait with EC as visibility_of_element_located
, so you have to: 作为下拉需要更长的时间来填补,所以你应该调用WebDriverWait与EC作为
visibility_of_element_located
,所以你必须:
Replace: 更换:
def dropdown(dropdownid, dropdownvalue): select = Select(driver.find_element_by_id(dropdownid)) select.select_by_visible_text(dropdownvalue) sleep(5)
with: 与:
def dropdown(dropdownid, dropdownvalue): select = Select(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "dropdownid")))) select.select_by_visible_text(dropdownvalue)
Note : You have to add the following imports : 注意 :您必须添加以下导入:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
You should use WebDriverWait ! 您应该使用WebDriverWait !
You can use presence_of_all_elements_located
on the list of select items... 您可以在所选项目列表中使用
presence_of_all_elements_located
...
An example: 一个例子:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
WebDriverWait(driver, 10).wait.until(EC.presence_of_all_elements_located((By.ID, dropdownid)))
Hope this helps! 希望这可以帮助!
