/* eslint-disable jest/no-commented-out-tests */

/*
  Currently, we need a patch, preventing Jest from crashing tests when rejected Promise is not handled.
  It is applied in `postinstall.sh` script.

  ### Example:
  ```ts
  it('should succeed, but crashes', async () => {
    Promise.reject(); // Normally such code does not crash entire runtime
    await new Promise(r => setImmediate(r));
    expect('42').toEqual('42');
  })
  ```
