This ticket tracks making it easy to run the existing Android JUnit 3 instrumentation test suites (browser and background) locally. This avoids a bunch of pain arranging for debug APKs to get to TBPL, and writing mozharness test runners.

Bug 1171566 - Part 1: Configure Gradle and Spoon. r?mcomella,liuche There are few things happening here: * A purely mechanical move of test sources into org.mozilla.test.browser.junit3. This is only to make it easy to specify the suite in Spoon. (But it has the advantage of making it possible to move files around in IntelliJ, since the symlink points to src instead of org/mozilla/gecko.) * Specifying the suite (package name) ended up requiring changes to the spoon-gradle-plugin anyway. Hence, I've included this custom spoon-gradle-plugin version locally, while I work to upstream the changes. * Some Gradle trickery to make |mach gradle runBrowserTests| execute Spoon with the correct package name.

Bug 1171566 - Part 2: Remove BrowserTestCase. r?mcomella,liuche This was just a remnant from earlier days. This launched the Fennec activity, which is absolutely *not* something we want to do during these browser JUnit 3 tests. That is, these should be pure instrumentation tests that just run Java code in the correct package and Java classloader context. They shouldn't interact with the App lifecycle at all. Not all the tests pass; I took a shot at fixing one but don't care to dig deeply right now.

Given what I know and understand, lgtm - I think I'll have to do some research on Gradle syntax and layout before I really understand what's going on here though.

And since I didn't know what Spoon was, https://github.com/square/spoon Nice!

NI self to try this locally (oops!).

Move fast and [try not to] break things!
