Leaky Redwood+Jest 😬

This repo is to demonstrate how the jest setup included with Redwood causes a memory leak.

I've added a bunch of very simple test files ./api/src/*.test.ts that test 1 + 1 == 2.

If you run via:

node --expose-gc $(which yarn) jest --runInBand --logHeapUsage ./api/src/*.test.ts

The output on my machine shows the heap gradually creeping up:
