vitest-dev/vitest#3077 (comment)

docker build . -t vitest
docker run -it -v ./src:/app/src vitest /bin/bash

Play with configs, my findings:

1. It is more likely to hang when test cases failed. (not sure, you can try comment & uncomment data-testid="message" in Message.tsx)
2. Node 18/19 will hang, while it seems that there are no issues with version 20+.
3. Setting globals: true and using the global vitest function increases the possibility of hanging.
4. The higher count of tests, the higher the chance of hanging.
