问题就出在_Condition.wait上, 这个方法首先计算等等的结束时间, endtime = _time() + timeout 1. 然后不断的判断时间有没有到,如果没到,就等上delay*2的时间,每次等待最多0.05秒: while True: gotit = waiter.acquire(0) if gotit: break remaining = endtime - _time() if remaining <= 0: break...
3.2 显示等待函数应用二 通常使用WebDriverWait时,我们还会使用到EC即expected_condition,这里展示了显示等待的几种函数之间的区别 #coding=utf-8 from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.supp...
WebDriverWait(driver,10).until(EC.element_selection_state_to_be(driver.find_element(By.XPATH,"//*[@id='ur']/option[1]"),True)) #判断某个元素的选中状态是否符合预期,这里传入的是locator WebDriverWait(driver,10).until(EC.element_located_selection_state_to_be((By.XPATH,"//*[@id='ur']/...
python asyncio condition中有个方法叫wait_for,该方法接受一个不带参数且返回值为布尔类型函数。 没执行一次con.notify_all()操作。wait_for中的函数便执行一次判断,直至其结果为true. import asyncio def judg…

While Python has handy wait methods, we’ll be exploring waits in terms of test automation. Automation testing tools like Selenium provide methods for pausing the test execution of a thread until a condition is met. For the rest of this tutorial, we will demonstrate how to use waits with ...
2.显示等待:WebDriverWait()类 显示等待:设置一个等待时间和一个条件,在规定时间内,每隔一段时间查看下条件是否成立,如果成立那么程序就继续执行,否则就提示一个超时异常(TimeoutException)。 通常情况下WebDriverWait类会结合ExpectedCondition类一起使用。
If target element already satisfies the condition, the method returns immediately. Otherwise, waits for up to `timeout` milliseconds until the condition is met. **Usage** ```py order_sent = page.locator(\"#order-sent\") await order_sent.wait_for() ...
(driver,10));wait.until(new ExpectedCondition(){public Boolean apply(WebDriver d){boolean loadcomplete = d.switchTo().frame("right_frame").findElement(By.xpath("//center/div[@class='welco']/img")).isDisplayed();return loadcomplete;}});也可以自己预估时间通过Thread.sleep(5000);//等待5秒...
显式等待,WebDriver提供的针对元素级别的、灵活、智能的等待方法,通过配合until()、until_not()、ExpectedCondition等条件的使用,默认每500ms检查一次条件状态,可以及时将脚本从等待中唤醒,避免无效等待,在实际应用中推荐使用该方法。 该等待的调用方法如下: WebDriverWait(driver, 超时时长, 调用频率, 忽略异常).until...
