Pretty sure this is what has to be done...

1. There are some local modifications off of Robolectric-3.0 branch that must be rebased onto Robolectric-3.2

https://chromium.googlesource.com/external/robolectric/+/3.0-chromium

So it will be like...
git rebase --onto robolectric-3.2.2 robolectric-3.0 3.0-chromium
...or something and pray it works.

2. Update src/DEPS to point to the new 3.2-chromium commit

3. Update all the files in third_party/robolectric/BUILD.gn

4. Add the latest android-all.jar. Need to upload to GS bucket and commit sha1 file. Something like...
https://cs.chromium.org/chromium/src/third_party/robolectric/lib/android-all-5.0.0_r2-robolectric-1.jar.sha1

5. Follow these two docs to update some Robolectric APIS. Doesnt look bad.

https://github.com/robolectric/robolectric/wiki/3.0-to-3.1-Upgrade-Guide
https://github.com/robolectric/robolectric/wiki/3.1-to-3.2-Migration-Guide



I think that is it?

eh, this doesnt sound to bad actually. Will use this project to perfcrastinate a bit next week.

ASsigning back to myself

Just tried writing a test using robolectric, but realized that the version we have only supports lollipop (I needed LOLLIPOP_MR1 and preferably M).

So I had to fall back to using a normal Android test, which made me a little sad. Would be awesome to port it back to Robolectric at some point.

Got Robolectric 3.2 building locally. Needs way more changes than I initially thought.

We will need to also add the third_party library Xstream and also update third_party/guava and third_party/accessibility-test-framework libraries.

We will also need Java 1.8 on our bots before we upgrade.

Got all Robolectric suites working on 3.2.2

ok, should be fixed assuming CL sticks.

Can now write Robolectric tests with N-MR1 Android code. Also, Robolectric 3.2 has some slick features (like being able to run same test against multiple SDK levels, and more)

I want to resurrect some CLs for android proxy settings and find several android-all jars are missing. Should I file a new issue?
