Testing rgitui

Running the test suite

cargo test

Taking a screenshot for visual testing

First, make sure the app is built:

cargo build

Then run the screenshot script:

./scripts/screenshot.sh

This will:

  1. Start rgitui with the test repo (default: ~/repos/test-repo)
  2. Wait 3 seconds for the window to render
  3. Take a screenshot using grim (Wayland) or scrot (X11)
  4. Save to test_output/screenshot_TIMESTAMP.png
  5. Kill the app

Configuration

Copy .env and adjust:

RGITUI_TEST_REPO=/path/to/your/test/repo

Making the screenshot script executable

chmod +x scripts/screenshot.sh

Integration with AI-assisted development

Screenshots in test_output/ can be loaded using the Read tool to visually verify the UI appearance during development.

Unit test structure

Tests are in crates/rgitui/tests/integration_test.rs and test:

  • Repository can be opened with git2
  • Graph layout algorithm produces valid output for empty and real repos
  • Binary artifact exists after build (ignored, run manually)

Environment variables

Variable Default Description
RGITUI_TEST_REPO $HOME/repos/test-repo Path to git repo used for integration tests
