Slf4j Logging Enables Your Grails Apps To Avoid isDebugEnabled Code Clutter and String Creation Overhead
Using ‘isDebugEnabled’ to wrap logging statements that involve String concatenation is standard Java best practice, especially in loops, and in cases where the objects being logged have expensive toString operations.

In our previous posts we published a Maven-based solution that illustrated how to get Selenium tests running against a Grails application completely from the command line (thus enabling these tests to run in the context of a continuous integration build.)
