Re-add coverage tests

[TTitcombe]

Description

Coverage tests were removed in #23 as there was some issue with the bazel build. This was a temporary solution to get the PR merged. We should re-add the coverage tests.

Type of Test

• [ ] Unit test (e.g. checking a loop, method, or function is working as intended)
• [ ] Integration test (e.g. checking if a certain group or set of functionality is working as intended)
• [ ] Regression test (e.g. checking if by adding or removing a module of code allows other systems to continue to function as intended)
• [ ] Stress test (e.g. checking to see how well a system performs under various situations, including heavy usage)
• [ ] Performance test (e.g. checking to see how efficient a system is as performing the intended task)
• [X] Other... Code coverage

Expected Behavior

The CI build should have a task for code coverage. Code coverage fails if baselines statistics are not met (see #27)
