Issue type: test
Difficulty: 3
Estimated time: 1-2 days
Activity status: stale
Clarity: clear
Prerequisites: Basic Rust knowledgeFamiliarity with unit/integration testingUnderstanding of onefetch codebase structure
Newbie friendliness: 65
Research direction: Focus on the unchecked modules in the issue: printer.rs, image backends/mod.rs, iterm.rs, kitty.rs, sixel.rs, loc.rs, pending.rs, version.rs, and git.rs. Review existing tests in checked modules for patterns. See linked PRs #699 and #705 for integration test pointers. Consult maintainers about test framework (likely built in Rust tests) and any mocking strategies.
