等到selenium java不起作用（）
我需要等到页面上显示某些元素。 我创建了使用wait.ultil（endureconconditions.visibilityofelementLocated（））：
public void waitForElementPresentBy(By locator) {
try{
wait.until(ExpectedConditions.visibilityOfElementLocated(locator));
}catch (Exception e){
Assert.fail("Element was not become visible");
}
}
等待对象以下一步的方式初始化 - 我设置了300秒：
wait = new WebDriverWait(webDriver, 300);
但是这方法未正确执行。它不会等到我的元素可见。
当我添加thread.sleep（3000）时，它有所帮助。 但是如何等待元素不添加sleep（）？
I need to wait until some element will be displayed on page.
I have created method in which I have used wait.until(ExpectedConditions.visibilityOfElementLocated()):
public void waitForElementPresentBy(By locator) {
try{
wait.until(ExpectedConditions.visibilityOfElementLocated(locator));
}catch (Exception e){
Assert.fail("Element was not become visible");
}
}
wait object was initialized in next way - I have set 300 seconds:
wait = new WebDriverWait(webDriver, 300);
But this method is not executed correctly. It does not wait until my element will be visible.
When I added Thread.sleep(3000), it helped.
But how to waiting for element not adding sleep()?

根据API文档
visibilityFelementLostocated（locator）期望检查页面的DOM上存在元素并可见。可见性意味着该元素不仅显示大于0。 EM> 方法几乎是经过证明的，并且是一种强大的机制，可以等待某个元素的可见性 。有点不清楚您为什么感觉到 ...它不会等到我的元素被看到... 。更多细节将帮助我们以更好的方式理解问题。
但是，这里考虑了有关硒的可见性，但不是对执行测试的用户的眼睛。
注意a ：如果您使用 selenium4 您必须使用以下WebDriverWait符号：
注释B ：当您使用WebDriverWait时，请记住删除隐式等待 conplet。
As per the API documentation
visibilityOfElementLocated(locator)is the expectation for checking that an element is present on the DOM of a page and visible. Visibility means that the element is not only displayed but also has a height and width that is greater than 0.visibility_of_element_located() method is pretty much proven and a robust mechanism to wait for the visibility of a certain element. A bit unclear why you felt ...it does not wait until my element will be visible.... A bit of more details would have helped us to understand the issue in a better way.
However, here visibility is considered with respect to Selenium but not to eyes of the user executing the tests.
Note A: If you are using selenium4 you have to use the following WebDriverWait notation:
Note B: As you are using WebDriverWait remember to remove Implicit Wait conpletely.
