Adds test for undefined call.inputs.

[robotoer]

Summary by CodeRabbit

• New Features

  • Updated the method for deriving function signatures in the mock contract, enhancing its ability to handle cases with undefined input parameters.

• Tests

  • Added a new test case to the "Doppelganger" test suite to verify that the mock contract can handle read calls without defined input parameters, ensuring expected behavior during queries.

Walkthrough

The changes involve a modification in the src/mock-contract.ts file, where the calculateFnSigHash function now uses toFunctionSelector instead of toFunctionHash when handling cases of undefined or null call.inputs. Additionally, a new test case has been added to the "Doppelganger" test suite in test/mock-contract.test.ts, which verifies that the mock contract can successfully handle read calls without explicitly defined input parameters.

Changes

File	Change Summary
src/mock-contract.ts	Updated calculateFnSigHash to use toFunctionSelector(call.abi) instead of toFunctionHash(call.abi).
test/mock-contract.test.ts	Added a new test case to the "Doppelganger" suite to verify handling of read calls with undefined inputs.

Poem

In the land of code where rabbits play,
A test was added to brighten the day.
With mock contracts and calls so grand,
They check for outputs, just as planned.
Hopping through tests, with joy we cheer,
For every success, we hold dear! 🐇✨

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.
  -- 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.

125-144: Overall assessment: Good addition with room for minor improvements

The new test case is a valuable addition to the test suite, aligning well with the PR objective of testing undefined call inputs. It enhances the coverage of the mock contract's functionality. The suggested improvements aim to make the test more explicit and comprehensive in testing both defined and undefined input scenarios.

Line range hint 1-180: Consider adding tests and documentation for the updated behavior.

Given the change in the calculateFnSigHash function, it would be beneficial to:

1. Add unit tests that specifically cover the case of undefined call.inputs to ensure the new behavior works as expected.
2. Update the function's documentation to explain the behavior when call.inputs is undefined or null, and why toFunctionSelector is used in this case.

These additions would improve the code's maintainability and help future developers understand the intended behavior.

6-6: LGTM: Import statement updated correctly.

The addition of toFunctionSelector import from 'viem' is consistent with its usage in the calculateFnSigHash function. This change maintains backwards compatibility while introducing the new functionality.

---

51-51: Please clarify the change from toFunctionHash to toFunctionSelector.

The function has been updated to use toFunctionSelector instead of toFunctionHash when call.inputs is undefined or null. Could you please explain the reasoning behind this change and confirm if it's intentional? It would be helpful to understand how this affects the function's output and if any dependent code needs to be updated.
