Summary by CodeRabbit
WalkthroughRestructure and expand the manifest parsing feature file for greater clarity and coverage, introducing more descriptive steps and explicit failure scenarios. Refactor the Rust test step definitions to modularise parsing logic, add assertion helpers, and introduce new step definitions for detailed manifest state checks. Changes

Hey @leynos - I've reviewed your changes - here's some feedback:
- The multiple
when_*_checkedstep definitions all just call the same assertion—consider merging them into a single regex‐based step to DRY up boilerplate. - Instead of repeating the
#[expect(clippy::needless_pass_by_value)]on each step, you could apply a module‐level allowance or tweak the step signature to accept &str directly and reduce noise.

@coderabbitai Have the following now been resolved?

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain@leynos Looking at the current code in Issue 1: Multiple
These could be consolidated into a single regex-based step like: #[when(regex = r"^the (manifest version|target flags|action flags|manifest contents) (?:is|are) checked$")]
fn when_manifest_checked(world: &mut CliWorld) {
assert_manifest(world);
}
#[when("the parsing result is checked")]
fn when_parsing_result_checked(world: &mut CliWorld) {
assert_parsed(world);
}Issue 2: So one issue has been addressed, but the DRY principle concern with the multiple similar step definitions remains. 🏁 Script executed: Length of output: 3308 @leynos I need to correct my previous assessment after examining the actual current code. Both issues HAVE been resolved: Issue 1: Multiple #[when(regex = r"^the (?P<item>[a-z ]+) (?:is|are) checked$")]
fn when_item_checked(world: &mut CliWorld, item: String) {
match item.as_str() {
"parsing result" => assert_parsed(world),
_ => assert_manifest(world),
}
}This consolidates all the checking steps into one function with pattern matching, exactly as suggested. Issue 2: #![expect(
clippy::needless_pass_by_value,
reason = "Cucumber requires owned String arguments"
)]This applies to the entire module and includes a helpful reason comment, which is much cleaner than individual annotations. Both suggestions have been implemented excellently! The code is now more DRY and the clippy noise has been eliminated at the module level. |

2-5: Excellent approach to managing clippy warnings.The module-level expectation with a clear reason is much cleaner than individual function annotations. The reason accurately explains why owned String arguments are necessary for Cucumber integration.
8-8: Import addition looks correct.Adding the
givenmacro import to support the new step definition is appropriate.
11-22: Well-designed extraction of common parsing logic.The
parse_manifest_innerfunction effectively eliminates duplication between thegivenandwhensteps. Using&strparameter avoids unnecessary string cloning whilst maintaining the same functionality.
24-36: Clean and purposeful assertion helpers.The
assert_manifestandassert_parsedfunctions provide clear, reusable logic with descriptive assertion messages. They effectively support the consolidated step definition approach.
37-40: Appropriate addition of given step definition.The new
#[given]step properly mirrors the existing#[when]step and correctly delegates to the shared parsing logic. This supports the enhanced test scenarios effectively.
42-45: Effective refactoring to use shared logic.The updated
parse_manifestfunction appropriately delegates toparse_manifest_inner, eliminating duplication whilst maintaining the same interface.
