Explicit Wait in Selenium

Explicit Wait in Selenium

In this article, we would like to demo how to wait specific web element to be available before we can operate it.

For example, we may wait for the search field or button to be visible before we can input search text.

In selenium, wait for specific web element available is called “Explicit Wait”

Testing Scenario

In this sample script, we are going to

1. visit the web page, http://www.seleniumhq.org/.

2. Wait until the search field available

3. input “Selenium” once the search field is ready.
