Here are some of the popular presentations about SmartFrog
Distributed Testing with SmartFrog
Presented at Google London Test Automation Conference 06. This talk shows how to use SmartFrog as a test runner, deploying the application server, the database and tests, collecting and collating the results. This is how we test SmartFrog! You can use a distributed deployment framework for deploying and running its own test suite!
Beyond Unit Testing
Presented at ApacheCon Europe 2006. This presentation is a predecessor of the Google LTAC talk; it covers the whole swathe of functional testing technologies available for Java programs, including Cargo, Cactus and Selenium, as well as using SmartFrog as a test runner.
Introduction to Testing
This is presentation targeted at university CS students, to introduce the whole notion of testing as way of ensuring your code is ready to ship. It doesn't go into that much detail on functional testing at all, merely looks at the benefits for having tests in your code.
