Summary of Changes

Hello @ackkerman, 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 introduces a new integration test to confirm the correct execution of the gh-sync push command, ensuring it properly delegates to the underlying git subtree push functionality. This enhances the robustness and reliability of the gh-sync tool's interaction with Git subtrees.

Highlights

• New Integration Test: I've added a new integration test, push_executes_subtree_push, to tests/cli.rs.
• gh-sync push Verification: This test specifically verifies that when gh-sync push is executed, it correctly invokes the git subtree push command, ensuring the intended behavior for managing subtrees.

Code Review

The pull request introduces a new test case push_executes_subtree_push to verify the execution of subtree push. The review suggests using std::env::consts::PATH_SEPARATOR for better portability and .expect() for improved error messages.

[gemini-code-assist]

Consider using std::env::consts::PATH_SEPARATOR for constructing the PATH environment variable to ensure portability across different operating systems. The current hardcoded ":" separator is specific to Unix-like systems and will cause issues on Windows.

Suggested change

	"{}:{}",
	git_shim.parent().unwrap().display(),
	std::env::var("PATH").unwrap()
	);
	let path_env = format!(
	"{}{}{}",
	git_shim.parent().unwrap().display(),
	std::env::consts::PATH_SEPARATOR,
	std::env::var("PATH").unwrap()
	);

[gemini-code-assist]

Using .expect() with a descriptive message instead of .unwrap() would provide a more helpful error message if the PATH variable is not set, improving debuggability.

Suggested change

	std::env::var("PATH").unwrap()
	std::env::var("PATH").expect("PATH environment variable must be set")
