Google announced a new version of the App Engine SDK today with a couple of interesting features.

Given the strength of feeling in evidence in the forums and blogs I expect it’ll be the raising of the 1000 limit on datastore queries that will get the most comment, but I was much more interested in the unit testing framework.

Unit testing support in the GAEJ has been non-trivial, which I suspect pretty much leads to non-existent testing in most apps. If the support makes this easier – especially in testing datastore access and caching – then it’ll be a hit with me.

There already was a way of simulating the app engine through a test classes supplied by Google but I’m hoping this will make things easier.

We’re going to upgrade the SDK and test out the new test framework and will post our results here.
