First I want to mention that the setup of the proguard task was broken with regard to how it detect inputs and this broken incremental support. This should be fixed in 0.10 which was released yesterday).
The reason you want to run proguard on the test is not to obfuscate or shrink the test but to update the test code to reflect obfuscation in the tested code. Otherwise the tested app code won't match the code expected by the test and it'll fail. For libraries it's a bit different since the tested code is packaged with the test app. In case of a tested app/test app, the test app compiles with the output of the tested app javaCompilation put on its classpath. For libraries, it's the packaged libraries that's put on the classpath of the test app, so you don't get access to non-obfuscated versions of classes. Clearly this is not great when testing a library, and you probably would want to test the non-obfuscated version. Right now this would require you to test against a version that's not proguarded.
