/**
|
||
|
|
* Unit test for `runPgDump` in backup.service.ts.
|
||
|
|
*
|
||
|
|
* Regression: the dump promise must resolve once BOTH (a) the child process
|
||
|
|
* exits 0 and (b) the output file is fully flushed — regardless of which event
|
||
|
|
* fires first. The original implementation attached the file's `finish`
|
||
|
|
* listener *inside* the child `close` handler, but `stdout.pipe(out)`
|
||
|
|
* auto-ends the file when the child's stdout closes, so `finish` frequently
|
||
|
|
* fired before the listener was attached → the promise hung forever (observed
|
||
|
|
* end-to-end against a real pg_dump).
|
||
|
|
*
|
||
|
|
* We drive the spawn with `node` instead of `pg_dump` (injected via opts) so
|
||
|
|
* the test is deterministic and needs no database.
