errorMessage is an Error and this was relying on errorMessage.toString() in the .test below. When making the expectToFail return type stricter this becomes an error.

| `STDERR:\n${stderr}`, | ||
| ].join('\n\n'); | ||

Everything above here was just moved into the new Promise so the waitForMatch logic in the callbacks can resolve the promise.
| childProcess.stdout!.on('data', (data: Buffer) => { | ||
| stdout += data.toString('utf-8'); | ||
|
|
||
| if (options.waitForMatch && stdout.match(options.waitForMatch)) { |

Previously this did data.match which in theory could fail if the stdout was spread across multiple 'data' events (this was in the deleted if (options.waitForMatch below). Same with stderr.

| }); | ||

Note this changed from exit to close to ensure stdout/err have completed:
https://nodejs.org/api/child_process.html#event-close
The 'close' event is emitted after a process has ended and the stdio streams of a child process have been closed
https://nodejs.org/api/child_process.html#event-exit
When the 'exit' event is triggered, child process stdio streams might still be open.

... and cleanup a few typescript types.
I've been debugging a failing test where stderr is not being matched. I tried these fixes and figured they may as well be merged? 🤷
