How do I validate element (button) no longer present on the screen (was presented but is no longer) - Selenium Webdriver

Question

someone can help me?

How do I validate element (button) no longer present on the screen? It was presented. I clicked and the button disappeared (expected scenario). However, I want to validate/confirm that the button no longer exists on the screen. How do I proceed?

The button is located by id "btn-two".

Using Selenium Webdriver - Java.

Answer 1

I believe this can help you:

WebDriverWait wait = new WebDriverWait(driver, 10);

WebElement element = wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("btn-two")));

Thinking about it, just to have a comparison because I don’t have the project in Java, there is an example of Webdriverio (Javascript) that I use in my projects. It reverses the validation of wait:

$(selector).waitForExist(ms, reverse, error)

In this case the parameter reverse by default comes as false, waiting for the selector. If so true, he hopes that the selector will not bring any element.

I think you can do this :

assertFalse(driver.findelements(By.cssSelector("#btn-two")). size() == 0);
