Software Design Issue 📜

Purpose

Add unit tests to ClimaAtmos, and reach a code coverage of 70% in physically meaningful tests.

Cost/Benefits/Risks

Currently, we rely on integration tests in ClimaAtmos to make sure the code works well. Adding unit tests is an important step towards improving the quality of ClimaAtmos code.

People and Personnel

Components

Add unit tests for functions that can be tested in isolation, e.g.
- tendencies and closures that have analytical solutions
- type stability and allocation of individual functions
Add a small subset of integration tests with increasing complexity to make sure all the components can run
Note: The regression test we currently have can probably be improved too, but we do not plan to change it in this SDI.
