# Package-runtime fixtures

Single-file `@test` sources driven by `test/package/package_test.ww`
(the `make test-package` binary): `singlefile_runtime_outcomes`,
`published_binary_cli`, and `direct_binary_timeout_and_descendants`.
They exercise the driver's single-file `ww test` leg and the published
`-c` binary's own command surface (repeated globs, `-list`,
`-timeout-ms`); the directory-package legs of the same outcome classes
are owned by `test/package/cases/*`.

Fixture notes:

- The runtime recognizes `expectabort(); os.exit(nonzero)` as an
  expected abort because WW's abort primitive itself terminates with a
  normal exit status; the ABI cannot distinguish those two paths
  without a future abort hook.
- The lingering-descendant fixture blocks SIGTERM in its descendant, so
  the runner exercises its grace period and SIGKILL escalation before
  draining the record.
- The escaped-descendant fixture moves its inherited pipe writer into
  another process group for one second; the framed nonblocking protocol
  must return after the test leader and owned group complete, never
  waiting for pipe EOF.
