23rd April 2018 - 22nd August 2018 (4 Months) [certificate] [blog post]

Working for the community version of Riak, I am reworking a key component in running all sorts of tests for the Riak database. Basho¹ reinvented the wheel by building a custom test runner facility along with other tools to measure code coverage that were already were available as standard tools in Erlang. My task is to take the Riak test suites that are tightly coupled with the custom test runner and make them work with the standard Erlang tools for running intricate tests (Common Test).
