问题
I need to find IReadOnlyCollection<IWebElement> using WebDriverWait to make sure that elements had been rendered on page.
This is my code
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeout));
return wait.Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.ClassName("TextInput")));
This code failing on timeout. Meaning that could not find any elements on page with given class name. I added this line of code BEFORE my original code just to make sure that elements are present
var allInputs1 = container.FindElements(By.ClassName("textInput"));
And that line returns elements as expected.
So my conclustion is that
wait.Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.ClassName("TextInput")))
doesn't work as expected since that couldn't find elements that are for sure present on page.
What is the best way to find array of elements using WebDriverWait?
回答1:
Your conclusion is wrong. With FindElements you just make sure that elements are present.
The API documentation for VisibilityOfAllElementsLocatedBy states:
An expectation for checking that all elements present on the web page that match the locator are visible. Visibility means that the elements are not only displayed but also have a height and width that is greater than 0.
And obviously present is not visible.
I think you should try ExpectedConditions.PresenceOfAllElementsLocatedBy
