Set up code coverage for Robolectric tests #1497

vinitamurthi commented 4 years ago

We would like to get code coverage reports for our robolectric tests. The code coverage tool needs to be compatible with Kotlin and java, as well as work on Gradle and Bazel. Jacoco seems to be a good pathway, some useful links:

Jacoco for Kotlin: https://kevcodez.de/posts/2018-08-19-test-coverage-in-kotlin-with-jacoco/
Jacoco in Bazel: https://github.com/bazelbuild/bazel/tree/master/third_party/java/jacoco

CC @BenHenning @anandwana001 , let me know your thoughts on using Jacoco! Here's the link: https://www.jacoco.org/jacoco/trunk/index.html

FYI I found out that Bazel's android local tests do not support code coverage at all, and this is something we'll need to contribute directly.

May I work on this?
