MMM (MySQL Master-Master Replication Manager) is a set of flexible scripts to perform monitoring/failover and management of MySQL Master-Master replication configurations (with only one node writable at any time). The toolset also has the ability to read balance standard master/slave configurations with any number of slaves, so you can use it to move virtual IP addresses around a group of servers depending on whether they are behind in replication.

Integrity is the angel watching over your shoulder while you code. As soon as you push your commits, it builds, runs your tests, and makes sure everything works fine.

So, as a result, people using RESTful ideas to talk to browsers have to put the smarts back on the server. They invent new URLs which (for example) return a resource, but return it all wrapped up in the HTML needed to display it as a form for browser-based editing.

Metric_fu is a set of rake tasks that make it easy to generate metrics reports. It uses Saikuro, Flog, Flay, Rcov, Reek, Roodi, Subversion, Git, and Rails built-in stats task to create a series of reports. It's designed to integrate easily with CruiseControl.rb by placing files in the Custom Build Artifacts folder.

Or, you can test your Rack application (or Sinatra, or Rails, or Merb) using arbitrary HTTP client libraries, to check interoperability.

An example of the conundrum of transferring print documents to the web, one that has become legendary in some circles, is the film screenplay.

Rake tasks to run specs and tests in parallel, to use multiple CPUs and speedup test runtime.

We had a conversation about the fact that the 'TDD is about testing vs TDD is about design" debate that keeps popping up, especially now in the Ruby community.

Celerity is a JRuby wrapper around HtmlUnit – a headless Java browser with JavaScript support. It provides a simple API for programmatic navigation through web applications. Celerity aims at being API compatible with Watir.

I brought up the question whether tests should call the translation API when checking for the presence of a string.

Write declarative tests using nested contexts without performance penalties. Contest is less than 100 lines of code and gets the job done.

Passing the --profile flag to RSpec produces some additional output, namely the running times of the ten slowest examples in your specs.

Deadweight is RCov for CSS, kind of. Given a set of stylesheets and a set of URLs, it determines which selectors are actually used and reports which can be "safely" deleted.

decided to go fixtureless with Shoulda + Factory Girl. All good, except one problem. Slow as fuck tests. So here’s fast_context as a solution for it. fast_context compiles all the ‘should’s within a context into a single test.

Unit tests are to refactoring like a drop cloth is to painting. Both feel like more work at first but ultimately save you time by allowing you to move faster.

Riot differs primarily in that it does not rerun setup for each test in a context.

Mockito is a mocking framework that tastes really good. It lets you write beautiful tests with clean & simple API. Mockito doesn't give you hangover because the tests are very readable and they produce clean verification errors.

RESTClient is a Java application to test RESTful webservices. It can be used to test variety of HTTP communications.

Eventually you’ll forget that you used to spend hours testing your code in a browser, and start complaining that your automated tests are taking minutes to run! You’ll have intense debates with co-workers about what to test and how to test it properly. You’ll start writing the test first to expose the bug or missing feature, then write the code required to pass the test.

This is a group devoted to making JRuby a first-class application language for Android.

Imagine all the syntactical delights of Ruby and Haml for your JavaScript. You write in a nice language, but get normal JavaScript at runtime. All whilst having full access to 3rd-party JavaScript libraries (jQuery, PrototypeJS), debugging support (it becomes pure, readable JavaScript), existing support from test suites (it’s normal JavaScript) and growing support from various text editors (TextMate, Vim, Emacs).
