I renamed and added a new test in my test suite. Following these changes, the coverage from codecov is different from the coverage I get locally.
Based on this answer, I read the following information which proposes how to find the cause of the issue. In this case, I'm pretty sure the cause is the changing test names. What I don't understand is how to go from understanding the cause to finding a solution to the issue, i.e. getting codecov to run based on the new test names.
