Day-to-day Git for testers — quiz

You're halfway through editing a test file when you need to switch branches to investigate a flaky test. Your changes aren't ready to commit. What's the cleanest approach?

• Commit half-finished work just to get it off your branch
• git stash — save uncommitted changes onto a hidden stack, switch branches, do your investigation, then `git stash pop` to restore your work
• Copy the files to your desktop and re-paste them later
• Discard the changes and rewrite them from memory
