Rails Test Prescriptions to be Published by Pragmatic

Pragmatic Programmers

Rails Test Prescriptions, the eBook put out by Noel Rappin, Director of Rails Development at Pathfinder, has been picked up by Pragmatic.

Congratulations to Noel - he's done a great job of furthering testing best practices in rails, and this is a great reward. As he said "I’m very excited by this. I’ve wanted to work with Pragmatic for as long as they’ve been publishing books, and I’m thrilled that this particular project will be able to get wider distribution and access to Pragmatic’s editorial expertise and skill."

* The current free “Getting Started with Rails Testing” ebook will continue to be available. If, at some time in the future, there’s a better Getting Started tutorial in the Pragmatic book, it may be offered as a replacement.

* The update site for current Rails Test Prescription owners will continue to be available for the foreseeable future.

* There will be one more official update to the current Rails Test Prescriptions, probably around the end of August. This will wrap up the chapter or two I’m working on, and tie up some other loose ends.

* After that, errata and information about changes to test tools will most likely be handled via this blog and an errata page on the rails test prescriptions site.

This is Noel's 4th book with a major publisher, following Professional Ruby on Rails, wxPython in Action and Jython Essentials. We're happy for Noel and happy to have him at Pathfinder.

Help, My Test Is Failing!

Dot, dot, dot, dot, dot -- tests are passing, looks like it's time for lunch -- dot, dot, dot, dot, F. F? F? But the code works. I know it does. I think it does. Why is my test failing?

One of the most frustrating times as a TDD developer is that moment when a test is failing and you don't know why, as opposed to the more normal case where the test fails as expected. Here's a grab bag of tips, tricks, hints, and thoughts to get us all through that difficult time.

Self-promotion alert: More details about Rails testing can be found at Rails Test Prescriptions, there's a free getting started tutorial which contains an extensive section on Cucumber, and a nearly 300 pages and counting full book for $9. Thanks. Also, follow @railsrx on Twitter for testing tips and updates.

Ajax Testing: Doubling Down with Selenium and JMeter

This idea comes from my colleague John McCaffrey, but since he's having a bad case of blogger's block, I get to post about it.

For anyone who has developed tests for web applications with a tool like Selenium (or Watir), you know it is a sysiphean task, rolling the boulder of automated tests up the hill of a constantly changing application. The DOM changes, the text changes, the url's and parameter's change, iframes and onload events don't always play nice with your test recorder. Depending on the framework you are using, id's may change in unpredictable ways, forcing you to hack together brittle xpath expressions. Still, functional testing is important, so you persevere, spending countless hours in making those tests run clean.
