# Node.js hanging test diagnosis
## Contract
| Field | Bound contract |
|---|---|
| Trigger | node --test hangs, flaky tests, 'process did not exit', CI timeout after tests done, 'open handles', passes-alone-hangs-in-suite. |
| Authority | Reversible local: runs test binaries under timeouts and reporters and writes only test and teardown code in this repository; rollback is version control. No remote mutation. |
| Side effect | Runs test binaries with timeouts/reporters; edits test and teardown code. |
| Done | Isolated test passes repeatedly and the full suite exits 0; the previously leaked resource no longer keeps the process alive after the tests finish. |
## Inputs
- The hanging test command or file (required).
