This (not particularly elegant) native addon tests the effect of UV_THREADPOOL_SIZE on node-api. The test fails if Node.js allows more than UV_THREADPOOL_SIZE async tasks to run concurrently, or if it limits the number of concurrent async tasks to anything less than UV_THREADPOOL_SIZE.

The test schedules UV_THREADPOOL_SIZE + 1 async tasks and waits until UV_THREADPOOL_SIZE tasks are running concurrently. (If this never happens, the test times out.) All UV_THREADPOOL_SIZE tasks then wait for a second to see if the last task also starts running concurrently, which should not happen.

Admittedly, I hastily put this together and the code is sloppy. While having this test is good in any case, the main motivation is such that @anonrig can invoke the test from his own test in #48890.
