Wait for Elements Appearing at Different Times

How it works

One WebDriverWait can be reused for any number of conditions. Each until() call starts its own countdown from the full timeout, so a fifteen-second wait allows up to fifteen seconds for every element you pass it.

Waits run one after another, but the page's timers do not. On Appearing Elements both messages start their countdown when the page loads. The first wait returns after about five seconds, and the second then needs only about five more, so the whole task takes about ten seconds rather than fifteen.

There is a third message on the page, appearing15sec. Sizing the timeout means knowing which elements you depend on: waiting for that one too would need a total of about fifteen seconds.

About the assignment

The starter creates a fifteen-second wait. You use it twice, first for the five-second message and then for the ten-second one, printing each message once it is visible.

What you will do

1. 1Wait for the first message with visibilityOfElementLocated() and print its text after the label First:.
2. 2Use the same wait object for the second message and print its text after the label Second:.

Common mistakes

• Creating a new wait for each element

  It works, but there is nothing to gain. One WebDriverWait can run any number of until() calls.

• Expecting the waits to add up

  The two timers run in parallel from page load, so the second wait needs only about five more seconds and the whole run takes about ten, not fifteen. Size each timeout for the slowest single element.

• Reading the second message before waiting

  It is in the DOM but hidden, so getText() returns an empty string. Each element needs its own wait.
