Walkthrough

The update introduces a more resilient handling of coverage data in the merge_coverage method. By adding checks to bypass processing for undefined strength or when a line number is missing in line_coverage_dup, it enhances the robustness of the coverage reporting process, ensuring smoother operations and more accurate coverage insights.

Poem

🐇✨
In the land of code and sun,
A tiny change has just begun.
Skipping lines, with grace and fun,
For a coverage, second to none.
Bounding through, the task is done.

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>.
  • Generate unit-tests 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 tests 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

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.

[coderabbitai]

The conditional check added to the merge_coverage method effectively prevents the NoMethodError by ensuring both strength is not nil and the line number exists in line_coverage_dup before attempting to add coverage strengths. This is a direct and effective solution to the problem described in the PR objectives.

However, for improved readability, consider extracting the condition into a well-named method or variable. This can make the intent of the condition clearer and the code easier to understand at a glance.

- next unless strength && line_coverage_dup[line_number.to_i]
+ line_number_exists = line_coverage_dup[line_number.to_i]
+ next unless strength && line_number_exists
