Automated Testing Clinic Follow-Up: Capybara-Webkit Vs. Poltergeist/Phantomjs | Engineering in Focus
Automated Testing Clinic follow-up: capybara-webkit vs. polter... https://behindthefandoor.wordpress.com/2014/03/02/automated-... Engineering in Focus the Fandor engineering blog Automated Testing Clinic follow-up: capybara-webkit vs. poltergeist/PhantomJS with 2 comments In my presentation at the February Automated Testing SF meetup I (Dave Schweisguth) noted some problems with Fandor’s testing setup and that we were working to fix them. Here’s an update on our progress. The root cause of several of our problems was that some of the almost 100 @javascript scenarios in our Cucumber test suite weren’t running reliably. They failed occasionally regardless of environment, they failed more on slower CPUs (e.g. MacBook Pros only a couple of years old), when they failed they sometimes hung forever, and when we killed them they left behind webkit-server processes (we were using the capybara-webkit driver) which, if not cleaned up, would poison subsequent runs. Although we’ve gotten pretty good at fixing flaky Cucumber scenarios, we’d been stumped on this little handful. We gave up, tagged them @non_ci and excluded them from our build. But they were important scenarios, so we had to run them manually before deploying. (We weren’t going to just not run them: some of those scenarios tested our subscription process, and we would be fools to deploy a build that for all we knew wouldn’t allow new users to subscribe to Fandor!) That made our release process slower and more error-prone. It occurred to me that I could patch the patch and change our deployment process to require that the @non_ci scenarios had been run (by adding a git tag when those scenarios were run and checking for it when deploying), but before I could put that in to play a new problem appeared. -
Bdd & Test Automation
BDD & TEST AUTOMATION: HOW NOT TO SHOOT YOURSELF IN THE FOOT Mati Parv About the speaker Mati Parv Automation Engineer @ Proekspert [email protected] What this is about Introduction to BDD and related tools Retro-fitting automation: should you do it? How it worked out for us Automated UI testing in web applications Hands-on session Introduction: BDD What is BDD Behavior-Driven Development An "outside-in" methodology, starting from the outside by identifying business outcomes, drilling down into the feature set that will achieve these outcomes. Focuses on the "how" of the software, not the "why" Introduction: Cucumber Describe how the software should behave in plain text The descriptions are the documentation... ... and the tests... ... and the specification. Helps us deliver value, create software that matters Cucumber: Example Feature: Search courses In order to ensure better utilization of courses Potential students should be able to search for courses Scenario: Search by topic Given there are 240 courses which do not have the topic "BDD" And there are 2 courses A001, B205 that have the topic "BDD" When I search for "BDD" Then I should see the following courses: | Course code | | A001 | | B205 | What happened in our case? Retro-fitting automation to mature codebase Should you do it? When does it work? Use Cucumber as the testing tool Is it good enough? Downside: maintenance hell is easy to achieve What are the alternatives? Continue with manual testing? Not good enough! Use another tool? UI automation in web apps What's good Tests run in a web browser – headless or not Allows to emulate user behavior Can be part of a CI process Downsides Performance can suffer, especially in an actual browser Initial test writing can be time-consuming Hands-on session Setup Application under test http://bdd-workshop-ntd2013.herokuapp.com Prepared test template http://git.io/6wD9Jw Required toolset Ruby 1.9+ RSpec, Capybara, Selenium-Webdriver Template code from above git repository Questions?

Ruby on Rails™ Tutorial: Learn Web Developments with Rails
ptg8286261 www.it-ebooks.info Praise for Michael Hartl’s Books and Videos on Ruby on RailsTM ‘‘My former company (CD Baby) was one of the first to loudly switch to Ruby on ptg8286261 Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again.’’ —From the Foreword by Derek Sivers (sivers.org) Formerly: Founder, CD Baby Currently: Founder, Thoughts Ltd. ‘‘Michael Hartl’s Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. It’s an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to read just one book and feel like a Rails master by the end of it, pick the Ruby on RailsTM Tutorial.’’ —Peter Cooper Editor, Ruby Inside www.it-ebooks.info ‘‘Grounded in the real world.’’ —I Programmer (www.i-programmer.info), by Ian Elliot ‘‘The book gives you the theory and practice, while the videos focus on showing you in person how its done. Highly recommended combo.’’ —Antonio Cangiano, Software Engineer, IBM ‘‘The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.’’ —Greg Charles, Senior Software Developer, Fairway Technologies ‘‘Overall, these video tutorials should be a great resource for anyone new to Rails.’’ —Michael Morin, ruby.about.com ‘‘Hands-down, I would recommend this book to anyone wanting to get into Ruby on Rails development.’’ —Michael Crump, Microsoft MVP ptg8286261 www.it-ebooks.info RUBY ON RAILSTM TUTORIAL Second Edition ptg8286261 www.it-ebooks.info Visit informit.com/ruby for a complete list of available products. -
