test(primitives): add more test for tree

[hoank101]

Summary by CodeRabbit

• Refactor

  • Renamed method Concatenates to Concat for improved clarity.

• Tests

  • Added comprehensive test functions for tree index operations including GetBranchIndices, GetPathIndices, CalculateMerkleRoot, VerifyMerkleProof, GetHelperIndices, CalculateMultiMerkleRoot, and VerifyMerkleMultiproof.

Walkthrough

The recent changes involve renaming the Concatenates method to Concat in the GeneralizedIndicies struct for simplification in the index.go file. Additionally, a suite of new test functions has been added for various operations related to tree indices and Merkle root calculations, ensuring robust validation of these functionalities.

Changes

File Path	Change Summary
mod/primitives/pkg/ssz/tree/index.go	Renamed method Concatenates to Concat in GeneralizedIndicies.
mod/primitives/pkg/ssz/tree/index_test.go	Introduced test functions for GetBranchIndices, GetPathIndices, CalculateMerkleRoot, VerifyMerkleProof, GetHelperIndices, CalculateMultiMerkleRoot, and VerifyMerkleMultiproof.

Poem

🐇 In the garden where code doth grow,
Methods change, new tests bestow.
From Concatenates to Concat so neat,
Ensuring indices never miss a beat.
Among Merkle roots, proofs concur,
CodeRabbit smiles, with updates we ensure. ✨

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 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 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 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.

Line range hint 139-145:
LGTM! But verify the method usage in the codebase.

The renaming from Concatenates to Concat is approved as it simplifies the method name.

However, ensure that all method calls to Concatenates are updated to Concat.

Verification successful

Renaming verified successfully.

The method Concatenates has been correctly renamed to Concat, and all instances of the old method name have been updated in the codebase.

• Verified usage in: mod/primitives/pkg/ssz/tree/index_test.go

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify all method calls to `Concatenates` are updated to `Concat`.

# Test: Search for the method usage. Expect: Only occurrences of the new method name.
rg --type go $'.Concatenates'

Length of output: 28
