WebDriver playback

The WebDriver playback feature in Selenium IDE lets you run tests in any one of the most popular web browsers: Chrome, Firefox, HtmlUnit, Internet Explorer, and Opera. By default, the WebDriver playback feature is turned off and is inactive. To run Selenium IDE scripts through WebDriver, turn on the WebDriver playback settings.

Launch the Selenium IDE and choose Selenium IDE Options from the Options menu. Switch to the WebDriver tab and select the Enable WebDriver checkbox. Now, restart the Selenium IDE to enable the WebDriver playback feature. However, on changing the browser name, restarting the IDE is not necessary. The idea discussed in these two paragraphs is shown in the following screenshot:

Prerequisites for the WebDriver playback feature

The following are the prerequisites that need to be fulfilled to enable the WebDriver playback feature:

Download the latest Selenium Server standalone library (JAR) file
Install Java to start the Selenium Server
Download the latest drivers for popular browsers (chromedriver, IEDriver, and so on)

Selenium Server can be initialized manually from the terminal or Command Prompt. Open the terminal or Command Prompt, locate the Selenium Server JAR file, and run the command using the following syntax:

java -jar selenium-server-standalone-<version-number>.jar

Now you can run the command:

java -jar selenium-server-standalone-2.44.0.jar

Click on the Selenium IDE Play Prerequisites for the WebDriver playback feature button to drive tests through WebDriver. To run tests in the Chrome web browser, replace the text firefox with chrome under the Selenium IDE options, as shown in the following screenshot:

By default, it is essential to set the ChromeDriver path in your working machine. Download the latest ChromeDriver extension from http://chromedriver.storage.googleapis.com/index.html?path=2.9/.

Follow these configuration steps to set the ChromeDriver extension path for different platforms.

On Windows:

Double-click and open the My Computer window.
Right-click anywhere on the window and select Properties.
Click on Advanced System settings.
Click on Environment Variables from System Properties.
Under System variables, select the variable named Path and click on the Edit button.
Now, extract the downloaded ChromeDriver package and copy the location path.
Paste the extracted location in Path (under System variables) and click on OK.

On Linux:

Open the terminal and run the following command:

$ wget http://chromedriver.storage.googleapis.com/2.7/chromedriver_linux64.zip
$ Unzip chromedriver_linux64.zip
$ cp chromedriver /usr/local/bin
$ chmod +x /usr/local/bin/chromedriver

On Mac:

Unzip/extract the zipped package (chromedriver_mac32.zip).
Copy and paste ChromeDriver to /usr/bin.
It will prompt you to enter the admin password; enter it to set the path.
