/*
|
|
* Shared test helpers for libakerror.
|
|
*
|
|
* Installs a capturing implementation of akerr_log_method so tests can assert
|
|
* on the *content* of log/stacktrace output (messages, status codes, error
|
|
* names) instead of relying solely on process exit codes.
|
|
*
|
|
* Also provides AKERR_CHECK(), a NDEBUG-proof assertion that fails the test by
|
|
* returning non-zero from main() (unlike assert(), which is compiled out in
|
|
* release builds and would silently turn a test into a no-op).
