Summary of Changes

Hello @ChanTsune, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on improving code quality and adhering to Rust's idiomatic practices by refactoring several for loops within the CLI test suite. The changes specifically target instances where loops were iterating over arrays containing only a single element, a pattern flagged by the clippy::single_element_loop lint. By introducing a temporary variable for these single-element arrays, the code becomes clearer and aligns with recommended Rust style.

Highlights

• Code Refactoring: Refactored for loops that iterate over single-element arrays in various CLI test files to improve code style.
• Clippy Lint Adherence: Addressed the clippy::single_element_loop lint by introducing an intermediate variable for single-element array iteration, making the code more idiomatic.

Code Review

This pull request aims to fix the clippy::single_element_loop lint. While the changes successfully silence the lint, they do so by introducing an intermediate variable, which makes the code slightly more verbose. A more idiomatic and clearer approach would be to remove the single-element loops entirely and perform the assertions directly. I've left suggestions on all occurrences to refactor the code this way for better readability and conciseness.
