Dealing with failing tests when all you have is a map for code

Mechanisms:

• Highlight tests in green.
• Run all tests on any change.
• Highlight failing test cases in red.
• Turn edges of vision red when there's any failures, just in case failing tests are out of view.
• Hotkey to zoom out over all of current view.
• Same hotkey to restore viewport settings.
• Click anywhere to zoom in.
