This pull request introduces a new type alias for
exec.ExitError
and adds comprehensive tests to ensure its correct usage and compatibility. The main focus is on verifying the type identity and behavior of the new alias, as well as its interoperability with the originalos/exec.ExitError
.Type alias addition:
ExitError
forexec.ExitError
inexec.go
, allowing for simplified and consistent error handling throughout the codebase.Testing enhancements:
TestExitError
test suite inexec_test.go
to verify the type identity betweenExitError
andexec.ExitError
, including bidirectional type assertions and ensuring they reference the same underlying object.ExitError
andexec.ExitError
, and that their methods (ExitCode
,Error
, andProcessState
) behave as expected.CommandContext
, ensuring the alias works in this context as well.
