@glaforgeGR8Conf keynote was live streamed and it is already posted in Youtube. How do I feel about Groovy's future after watching the talk? Reassured. He recaps the events that triggered the move into the Apache Foundation and he shouts a clear message We are here to stay.
I bought the MEAP edition but the finished PDF has been already release. The book has 915 pages. Wow! Needless to say, I've not read it yet. However I read the Database Programming with Groovy chapter this week for some work we had to do in our company and it helped us out big time.
Tip, you will find a GR8Conf promo code in the "Groovy Sate of the Union" video I posted before.
@ilopmarGR8Conf talk Testing with Spock: The logical choice is backed up by a Github repository where you could find an great set of Spock examples. I've linked directly to the test folder. Learn about Timeout, IgnoreIf and DataDriven tests with Spock. And yes, the old test is really cool.
If you want to learn how to do functional testing, check out the @JacobAaeGR8Conf talk slides. He does a good job explaining what is Geb and how to use pages and modules to keep you Geb tests maintainable. Moreover, he explains how to use it inside your Grails (2.x or 3.x) webapps.
Geb is really of interest to me because at work I do a lot of screenscraping.
@saschakleinGR8Conf talk Android on Groovy follows last week Groovy Dev Weekly flavour. Lets use Groovy on Android! Inside you will find great comparisons between Java code and Groovy code on Android. They are pretty explanatory about how can Groovy simplify Android Development.
Moreover, It contains a brief introduction to SwissKnife. A Groovy library containing view injection and threading for Android using annotations.
