Explicit Wait - Element Clickable

How it works

ExpectedConditions.elementToBeClickable() holds when the element is visible and enabled, and until() then returns the element. It is the usual wait before a click() on a button that starts disabled, such as Submit before a form is valid.

It does not check whether something covers the element. If a spinner overlay or a cookie banner sits on top, the wait still succeeds and the click() that follows throws ElementClickInterceptedException. For that case, wait for the overlay to disappear first, as lesson 38 does.

When the element stays disabled the wait fails with a specific message. On the Buttons page, waiting two seconds for disabledButton throws TimeoutException with "to be clickable, but the element was not enabled".

About the assignment

The starter creates a ten-second wait for you. You wait until the left-click button is ready, report that the wait succeeded, click the button it returned, and print the label the click produces.

What you will do

1. 1Pass ExpectedConditions.elementToBeClickable() with the button's id to wait.until() and keep the returned element.
2. 2Print that the button is clickable after the label Button is clickable:. If the wait had failed, it would have thrown, so reaching this line is the proof.
3. 3Click the returned element.
4. 4Print its text after the label After click:.

Common mistakes

• Finding the element again after the wait

  It works, but it is a second lookup for something you already have. Use the element until() returned.

• Expecting a boolean from until()

  This condition returns a WebElement, so assigning the result to a boolean does not compile.

• Treating clickable as unobstructed

  An element under an overlay still passes this wait, and the click then throws ElementClickInterceptedException.
