Summary by CodeRabbit
No user-facing changes in this release. WalkthroughAdd a new public helper ensure_manifest_exists in test_support to resolve a CLI manifest path (absolute or relative), create and persist a minimal manifest file when missing, and return the resolved PathBuf. Replace inline manifest creation in tests/steps/process_steps.rs with a call to this helper. Changes

Here are the key additional facts and relevant context for reviewing PR #132, organized by category:
- Helper Location and Signature
- The new function is in
test_support/src/lib.rs, making it part of a separate test-support crate. - Signature:
pub fn ensure_manifest_exists(temp_dir: &Path, cli_file: &Path) -> PathBuf
- It replaces inline logic in
tests/steps/process_steps.rsand centralizes path resolution and file creation.
- Behavior of
ensure_manifest_exists
- Resolves
cli_fileto an absolute path undertemp_dirif relative, or uses it directly if absolute. - If the resolved manifest file doesn’t exist:
- Creates a temporary file (via
tempfile::NamedTempFile) intemp_dir. - Writes the manifest contents using
crate::env::write_manifest. - Persists the temp file to the resolved path.
- Creates a temporary file (via
- Returns the final
PathBufto use for the CLI’sfileargument.
- Impact on
process_steps::run
- Previously,
run()manually replicated ~23 lines of path logic and file writing. Now it simply does:let cli_file = world.cli.file.clone(); world.cli.file = ensure_manifest_exists(&dir, &cli_file);
- This exactly matches the objective in issue #59 of extracting those lines into a helper.
- Tests and Verification
- The PR runs
make fmt,make lint, andmake test. - All existing
rstest,cucumber-rs, andinstasnapshot tests pass, indicating the helper covers all prior scenarios. - No new tests were added for edge cases, but existing tests for manifest parsing and IR generation continue to pass unchanged.
- Linked Issue Confirmation
No unknown regressions or conflicting changes were found in other modules.

108-116: Keep doctest non-executable to avoid FS side-effectsYou correctly annotated the example with rust,no_run. This resolves the earlier feedback and keeps docs useful without mutating the filesystem during doctests.
125-134: Create parent directories and persist within destination FSYou now create the parent directory and create the temp file in the destination directory before persisting. This removes cross-filesystem rename pitfalls and fixes missing-parent failures.

Summary of additional relevant facts for reviewing PR #132:
- Helper placement & signature: new helper added to test_support crate at test_support/src/lib.rs as
pub fn ensure_manifest_exists(temp_dir: &Path, cli_file: &Path) -> PathBuf. - Behavior: resolves relative cli_file under temp_dir or uses absolute path; if missing, creates a NamedTempFile in temp_dir, writes a minimal manifest (via crate env/write_manifest), persists it to the resolved path, and returns the resolved PathBuf. Replaces ~23 lines of inline manifest-creation logic previously in tests/steps/process_steps.rs.
- Call sites: tests/steps/process_steps.rs now calls the helper and assigns its return to world.cli.file before invoking run_ninja; NamedTempFile usage removed from that test.
- Tests & CI: PR runs make fmt, make lint, make test; existing rstest, cucumber-rs, and insta snapshot tests remain green per PR notes — no new tests added targeting edge cases (e.g., permission errors, conflicting paths).
- Linked issue: PR closes issue #59 ("Extract manifest path resolution logic into helper function") and matches the requested scope (parameterization by temp_dir and cli_file, resolving absolute vs relative, creating/persisting temp manifests, returning resolved path).
- Potential review notes: behavior relies on test_support::env::write_manifest and NamedTempFile persisting to the resolved path — verify atomicity/permissions in cross-platform CI and consider adding explicit tests for absolute-path input, existing-file (no-op), and error propagation on write failures.

tests/steps/process_steps.rs (2)
9-13: Import the manifest helper to centralise setupImport ensure_manifest_exists from test_support to reuse the shared manifest resolution/creation logic. This removes duplication from step code and aligns with the refactor’s objective.
83-86: Verify step assertions that depend on the raw CLI pathOverwriting cli.file with the resolved (often absolute) path can affect steps that assert equality against the originally provided string (see tests/steps/cli_steps.rs Line 103). Verify no scenarios assert the manifest path after the run step using the un-resolved form.
If any such assertions exist, update those steps to compare against the resolved path or to normalise the expected value the same way ensure_manifest_exists does (resolve relative input against the temp dir before asserting).

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain@leynos: No, neither of these issues have been resolved in the current implementation. Looking at the Issue 1 - Missing parent directory creation: temp_file.persist(&manifest_path).expect("Failed to persist manifest");This will fail if Issue 2 - Generic error messages: env::write_manifest(&mut temp_file, &config).expect("Failed to write manifest");
temp_file.persist(&manifest_path).expect("Failed to persist manifest");Recommended fixes:
if let Some(parent) = manifest_path.parent() {
std::fs::create_dir_all(parent)
.expect(&format!("Failed to create parent directories for {}", manifest_path.display()));
}
env::write_manifest(&mut temp_file, &config)
.expect(&format!("Failed to write manifest to {}", manifest_path.display()));
temp_file.persist(&manifest_path)
.expect(&format!("Failed to persist manifest to {}", manifest_path.display()));Both improvements are needed to make the function more robust and debuggable. 🏁 Script executed: Length of output: 4572 @leynos: I need to correct my previous assessment after examining the actual code: Issue 1 - Missing parent directory creation: ✅ RESOLVED let dest_dir = manifest_path.parent().unwrap_or(temp_dir);
if !dest_dir.exists() {
fs::create_dir_all(dest_dir).expect("Failed to create manifest parent directory");
}Issue 2 - Generic error messages:
However, they still don't include the fs::create_dir_all(dest_dir).expect(&format!("Failed to create manifest parent directory for {}", manifest_path.display()));
