Using Cucumber, Webrat and Selenium to test ajax form field validations

September 4th, 2009 • 2 comments Cucumber, Internet, JavaScript, Merb, Ruby, Webrat, programming

I have an app that fires an ajax request on a form field to validate its contents when I take focus off the field.

I am also using Cucumber, Webrat and Selenium for my integration tests.

I needed my integration tests to test the Ajax responses and the tests weren’t receiving a response from the Ajax requests.

The Problem

I found that by simply completing the web form, the ajax request was not being fired and my test was therefore failing when i checked for the existance of the Ajax response. It soon became clear that selenium doesn’t really interact with the form in the sense of selecting fields and entering values; It simply enters values. As such, the Ajax request was not firing and my test was failing.

The Solution

The solution is Selenium’s fireEvent method, which you can pass a form field id and the blur method:

selenium_session.fireEvent(”field”, “blur”);

In Webrat, this is ever simpler:

fire_event(”field”,”blur”)

On using this in a Cucumber step, the ajax is fired as the blur command tells the browser to take focus off the field.

Lovely!

Sproutcore – 1st impressions

Today i had a short play with Sproutcore (the “Cocoa for the Web” JS framework used by and optimized by Apple for me.com) for the first time. I was a little surprised with what i found.

The Great

• The development tools are in Ruby using the merb framework
• The development tools adopt a Rails like MVC architectural pattern, with commands like 

sc-gen model example/contact
sc-gen controller example/detail
sc-gen view example/card
