Everything You Should Know About Waits in Selenium

Selenium Webdriver is a platform-independent tool used to automate testing of web applications to verify that it operates as demanded. Selenium supports many different browsers such as Firefox, IE, Chrome, and Safari. However, this tool does not qualify for applications based on the windows.

It also helps in supporting many different programming languages such as Java, Perl, C#, PHP, and Ruby for writing the test scripts.

The Wait Commands in Selenium

The wait commands are crucial when there is a need to execute Selenium tests. In addition, waits help recognize and troubleshoot the issues that may occur due to changes in time lag. For example, when the browser loads a page, then there is a possibility that the elements with which we want to interact with may load at different periods.

Hence it becomes difficult to recognize the element but also if the component is not determined, it will show the “ElementNotVisibleException” exception. Using Selenium Waits, this problem can be resolved very quickly.

Different Waits of Selenium Web Driver

❖ Implicit Wait in Selenium

The Implicit Wait in Selenium tells the web driver to wait before throwing “No Such Element Exception” for a specific amount of time.

• Implicit Wait time applies to all the elements in the script
• There is no need to define “ExpectedConditions” on the element to be identified in the implicit wait
• It is advised to use when the elements are identified with the time frame specified in Selenium implicit wait

For example, if we declare an implicit wait with a time frame of 10 seconds and the element is not found on the web page within that period, it will throw an exception.

Import the following package to add implicit waits in test scripts:

import java.util.concurrent.TimeUnit;
