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...
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() ``` ```py order_sent = page.locato...
2、until()或者until_not()方法的使用: # 直到满足condition返回True WebDriverWait(driver,timeout,poll_frequency=0.5,ignored_exceptions=None).until(condition,message="") # 直到满足condition返回不是True WebDriverWait(driver,timeout,poll_frequency=0.5,ignored_exceptions=None).until_not(condition,message="...
WebDriverWait(driver, 10).until_not(lambda driver:driver.find_element_by_id("someId")) 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 ...
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。
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…
(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...
