Walkthrough

A new documentation file describes a proposed companion crate, wireframe-testing, which provides asynchronous utilities for unit and integration testing of WireframeApp instances using in-memory duplex streams. The document details the crate's motivation, layout, API, example usage, and outlines next steps for implementation and migration of existing helpers.

Changes

Poem

In docs a new crate’s tale is spun,
For testing apps without network run.
With duplex streams and async cheer,
Your frames and bytes are handled here.
A bunny’s hop, a helper’s leap—
Now testing’s simple, fast, and neat! 🐇

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and explain its main purpose.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

83-88: Format Next Steps as a list
Converting the action items into a bulleted list will improve scannability and align with earlier sections.

- Implement the crate in a new directory, export the helper functions, and migrate
- existing tests to use them. Additional fixtures (e.g., prebuilt frame
- processors) can be added over time as test coverage grows.
+ - Implement the crate in a new `wireframe-testing/` directory and export the helper functions.
+ - Migrate existing tests to leverage the new crate.

9-15: Motivation section is clear
The rationale for extracting test helpers into a dedicated crate is well-stated and the relative link to tests/ looks correct. No changes needed here.


74-82: Benefits section is well-structured
The bullet points succinctly capture isolation, reusability, and clarity. British spelling “behaviour” is used consistently. No edits necessary.

Hey @leynos - I've reviewed your changes - here's some feedback:

  • Rename the crate folder/name from wireframe-testing to wireframe_testing to align with Rust module naming conventions and allow seamless use wireframe_testing imports.
  • Consider providing variants of the helpers that borrow or mutably reference the WireframeApp (e.g., &mut WireframeApp) so tests can reuse the same app instance across multiple calls.
  • Clarify how stream errors or malformed/incomplete frames are surfaced by these helpers to make writing failure‐scenario tests more straightforward.

1-6: Approve heading and introduction
The title clearly names the crate and the intro concisely explains its purpose.


24-30: Crate layout TOML snippet is correct
The provided [dependencies] and [dev-dependencies] sections accurately list tokio and rstest.


75-79: Capacity variants code samples are present
The signatures for drive_with_frame_with_capacity and drive_with_frames_with_capacity are included and marked pub, matching existing helpers.
