Behat is an open source behavior driven development framework for php 5.3.
Behat was inspired by Ruby's Cucumber project and especially it's syntax part (Gherkin). It tries to be like Cucumber with input (Feature files) and output (console formatters), but in core, it built from the ground on the shoulders of giants:
Symfony Dependency Injection component Symfony Event Dispatcher component Symfony Console component Symfony Finder component Unlike any other php testing framework that tests applications inside out. Behat is testing applications outside in. It means, that Behat works only with your application's input/output. If you want to test your models - use unit testing framework instead, Behat created for behavior testing (but can be used for anything +) ).
Also, there's symfony plugin for Behat, so you can start testing your applications right now.
One of the great difficulties of Facebook application development is the difficulty in running large-scale tests due to the large number of Facebook accounts required, and the Facebook Terms of Use which does not allow automated systems to access the Facebook servers. These issues are explained in depth in Load testing Facebook apps (Part 1) and Load testing Facebook apps (Part 2). FriendRunner acts as a drop-in replacement for the Facebook servers, and so allows you to run your tests with as many users as you'd like. Furthermore, FriendRunner's automated test system runs the entire test for you once you create a test script to define the actions for a single user.
Super simple setup Setting up an A/B test couldn’t be easier. Almost everything is done for you. You can be running multiple tests in only a matter of minutes.
Test anything Whether you want to test changes to your copy, HTML, CSS, javascript, or test completely different designs, phpA/B offers a way to do it.
Google Analytics integration phpA/B integrates automatically into your Google Analytics, allowing deeper insight into your tests’ impact on users.
High performance PHP-based tests run before users even begin loading your web pages. Javascript-based A/B tests cause funny twitches in your UI.
Search bot filtering Don’t let search engine robots skew your data. phpA/B automatically filters them out of your tests.
Have you ever wondered how optimized your Memcached installation is? There is a common misconception that one doesn't have to think too deeply about Memcached performance, but that is not true. If your setup is inefficient, you could:
* Burn Memory
* Waste Network Round-Trips
* Store Keys That Never Get Retrieved
* Have a Low Cache Hit Ratio (i.e. query MySQL too much)
* Suffer a fate too horrible to contemplate.Percona does a lot of consulting around Memcached, so we try to take a quantitative, scientific approach to measuring memcached performance, just like everything else we do.
