Test Suites

This is the list of what the tests cover, folder by folder. How to run them, the helpers and the rules are on Testing. On 2 October 2026 the Vitest suites held 934 tests in 96 files and the Rust code had 424 #[test] functions for cargo test; the numbers grow with every feature, so treat them as a rough size, not a target.

Rust tests (cargo test)

Most modules test themselves in a #[cfg(test)] block; the bigger ones have a tests.rs beside them.

Module	What the tests cover
commands/tests.rs	whole commands against real repositories: staging, commits, conflicts, mergetool, file operations and files_exist
commands/*.rs	branch actions, commit options, history, ignore files, Merge and Rebase options, patches, interactive rebase (with merges), remotes, clone and cancel, shelf, stash, status, tags, config
git/tests.rs and git/*.rs	readers and the CLI runner, the demo script, blame, cancel, files, LFS, submodules, worktrees
merge/engine.rs	the 3-way engine and its oracle test against git merge-file
watcher.rs	attribution, ignored paths, linked git folders, index invalidation
terminal.rs, run_process.rs	shells, PTYs, hang up and kill, script runs and the login environment
scripts/, node_versions.rs	each script file format, the wanted Node version, installed versions
file_search.rs, symbols/, text_search/	indexing, matching, caps, cancel, the symbol scanners, Replace in Files
git_console.rs	recording, masking secrets, limits, off means nothing
shelf/	patch sections and the store
github/tests.rs	every GitHub path against a fake network, keychain and gh
