Dynamic/Random Javascript values in Selenium IDE

01 January 2011

One of the common questions I see from new users to Selenium is how to insert random values into a form. Well it turns out this is quite easy. Simply change your value to some javascript surrounded by some special syntax:

javascript{[code goes here]}

So let’s do this using a more practical example. You have a form where you can’t enter the same data twice for example a registration form would require a unique email address. So, record your test as normal, entering real data then once you’re finished go back and edit the type command for the email address field and set the value to:

javascript{new Date().getTime() + "@example.com"}

Now you have random data you can pass into your test to ensure it passes any unique validation tests every time.
