I add a focused test suite for one module or feature in your codebase (JavaScript/TypeScript, Python, or Go), using the test framework you already have, with a short note on what is and isn't covered. Delivery: a pull request to your repo; you review and merge. Turnaround: 3 business days after repo access and a pointer to the module. I don't change application behavior; if I find a bug I write a failing test and describe it.
