如何摆脱硬编码的sleep()? [英] How to get rid of the hardcoded sleep()?

问题描述

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)

这2个功能正常工作，但是我使用的是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填充时间，因此我必须放置最长的睡眠值才能避免出错，如何使用wait修复这两个功能.

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.

推荐答案

在 WebElement 项目上调用send_keys()时，理想情况下，您应该调用 WebDriverWait ，其中 EC 为element_to_be_clickable，因此您必须:

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:

• 替换:

• Replace:

def textfield(boxid,textadded):
    project = driver.find_element_by_id(boxid)
    project.send_keys(textadded)
    sleep(3)

具有:

with:

def textfield(boxid,textadded):
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "boxid"))).send_keys(textadded)

由于下拉列表需要更长的时间，因此您应使用 EC 作为visibility_of_element_located调用 WebDriverWait ，因此您必须:

As the drop-down take longer to fill so you should invoke WebDriverWait with EC as visibility_of_element_located, so you have to:

• 替换:

• Replace:

def dropdown(dropdownid, dropdownvalue):
    select = Select(driver.find_element_by_id(dropdownid))
    select.select_by_visible_text(dropdownvalue)
    sleep(5)

具有:

with:

def dropdown(dropdownid, dropdownvalue):
    select = Select(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "dropdownid"))))
    select.select_by_visible_text(dropdownvalue)

注意:您必须添加以下导入:

Note : You have to add the following imports :

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