Get Code Coverage >= 90%

(Follow-up #7623)

After completing the migration to Codecov, our code coverage will be approximately 74.53%. I recommend the following action steps:

• Set a minimum enforcement threshold of 70% coverage (See https://docs.codecov.com/docs/codecov-yaml)
• Work towards increasing overall code coverage to 95% or higher
• Once achieved, enforce a minimum of 90% coverage
