• In these test helpers, Files.delete(tempFile) in a finally can throw and mask the original failure from reading/parsing the archive, making debugging harder. Consider using deleteIfExists and suppressing/logging deletion failures (similar to tearDown()).

        } finally {
            if (tempFile != null) {
                Files.delete(tempFile);
            }

• Same concern here: Files.delete(tempFile) in the finally block can override the original exception from zip processing. Using deleteIfExists and suppressing/logging IOExceptions would keep the primary test failure visible.

        } finally {
            if (tempFile != null) {
                Files.delete(tempFile);
            }
