18. Using getEval( ) to re-size the browser window

As there is no direct command or predefined method in Selenium RC to re-size the browser window, we've to use getEval( ) Selenium RC predefined method which uses the JavaScript to perform few operations as shown below:

Syntax: getEval("JavaScript Code Here");

Example: getEval("alert("Hi")") -> This one will give alert message with text "Hi" while executing.

Here in this example you have to understand two things. i.e getEval( ) is a selenium RC predefined method where as alert("Hi") is the JavaScript code.

But we are in requirement of a JavaScript code which re-size our browser window. window.resizeTo(X,Y) is the JavaScript code to re-size the window. Here X and Y are height and width. Lets use this code with Selenium RC predefined method getEval( ) as shown below:

Example getEval("window.resizeTo(600,700)") -> This will re-size the browser window to 600 pixels width and 700 pixels height.

Lets Implement This:

1. Start the Selenium RC Driver as explained in our previous Post#14
2. Open the URL using the Selenium RC command as explained in our previous Post#15
3. Maximize the browser window having the opened URL using the Selenium RC command as explained in our previous Post#16
4. Re-size the maximized browser window in previous step to 600 pixels width and 700 pixels height by writing the getEval("window.resizeTo(600,700)");  into the Selenium RC code as shown below:

5. Save and Run the Selenium RC Code using JUnit and observe that the Browser window got re-sized to 600 pixels width and 700 pixels height as shown below:

Watch the Video on how the getEval("window.resizeTo(x,y)") command re-sizes the Test Browser Window:

6. But the execution was too fast. As a result we wont be able to clearly view when the window got maximized and then when it got re-sized properly. In order to view the execution steps with some delay, lets add Thread.sleep(3000) statements between the commands as shown below:

7. Save and Run the written Selenium RC code with JUnit. To understand how the Test has Run this time, watch the below video:
