Walkthrough

This pull request introduces a new GitHub Actions workflow that automates generating and reporting JaCoCo code coverage on pull requests targeting the main branches. It also updates the project’s Maven configuration by bumping the version, upgrading the Lombok library, replacing the Lombok and Cobertura plugins with the JaCoCo Maven plugin, and streamlining a utility method used for class name formatting. These changes integrate code coverage reporting into the CI process and refine the project's build configuration and utility logic.

Changes

Files Summary of Changes
.github/workflows/coverage-report.yml Added a new GitHub Actions workflow that checks out code, sets up JDK 8, builds/tests with Maven (triggering JaCoCo report generation), verifies presence of JaCoCo reports, and posts coverage reports as PR comments.
pom.xml Updated project version from 0.5.12 to 0.5.13-RC1, upgraded Lombok from 1.16.6 to 1.18.30, removed the lombok-maven-plugin and cobertura-maven-plugin, and added/configured the jacoco-maven-plugin (version 0.8.13).
src/main/java/com/flipkart/.../Utils.java Modified the name(Class<?> clazz) method to apply the case transformation directly during the mapping process rather than after retrieval.

Poem

I'm a little rabbit with joyful hops,
Celebrating code changes that never stop.
Coverage report now leaps into sight,
Maven and JaCoCo making our code light.
With each plugin update and tweak so neat,
My fluffy tail dances to a happy beat!

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.
    • Generate unit testing code for this file.
    • 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 generate unit testing code for this file.
    • @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 generate unit testing code.
    • @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.

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.

1-58: Well-structured GitHub Actions workflow for code coverage reporting.

The workflow is properly set up to:

  1. Run on PRs to main/master branches
  2. Set appropriate permissions
  3. Build and test the project
  4. Generate and post JaCoCo reports as PR comments

Two suggestions:

  1. Consider documenting the reasoning behind the 95% coverage thresholds in the workflow file, as this is quite high and may be challenging to meet initially.
  2. Add a newline at the end of the file to comply with YAML best practices.
  echo "Overall Coverage: ${{ steps.jacoco.outputs.coverage-overall }}%"
  echo "Changed Files Coverage: ${{ steps.jacoco.outputs.coverage-changed-files }}%"

src/main/java/com/flipkart/databuilderframework/engine/Utils.java (1)

32-34: Improved implementation of the name(Class<?>) method.

The change optimizes the implementation by directly applying the case format transformation within the computeIfAbsent lambda. This streamlines the code while maintaining the same behavior and thread safety provided by ConcurrentHashMap.

pom.xml (3)

7-7: Version update to 0.5.13-RC1.

This version increment indicates a release candidate for a new minor version.


65-65: Updated Lombok version from 1.16.6 to 1.18.30.

Good improvement to use a more recent version of Lombok, which likely includes performance improvements, bug fixes, and better compatibility with newer Java versions.


120-137: Replaced Cobertura with JaCoCo for code coverage analysis.

Adding JaCoCo is a good choice as it's more actively maintained than Cobertura and better integrated with modern CI/CD workflows. The configuration looks standard with the prepare-agent and report goals properly configured.
