Both of Greptile's findings on #591 were real, and the first was a plain miss: mockModule shipped with no caller, so its documented usage had never once been executed and could not have worked. It called jest.requireActual on a path passed in by the spec, which resolves relative to test-utils.js rather than to the caller -- for any spec in a subdirectory the documented '../hooks/customHooks' pointed outside src altogether. It now takes the module the spec has already resolved, and throws on a string rather than quietly resolving to the wrong one, which was the original failure. It also has a caller now. FileBrowser.test.js listed six hooks in a hand-written factory and returned only those, so every other export of customHooks was undefined for anything it rendered -- the exact landmine the helper exists to remove. The second: `inverted` drove Mantine's colour scheme on its own, so asking for night or amber through the new theme option produced a tree that reported a dark theme while Mantine rendered its light one. Production cannot reach that combination, and a harness that invents states the app never has is worse than one that is merely incomplete -- what a test proves about such a tree is true of nothing. The scheme is now derived from the theme name via isDarkTheme, and data-theme is stamped on <html>, without which a component test cannot exercise any token table or the night-mode treatment at all. isDark remains overridable so a spec can still make the two disagree deliberately. test-utils.test.js covers the harness itself, which had none. Eight of its twelve assertions were red against the code above. 986 jest, 46 e2e, clean cache-busted build, tsc clean. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more
information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will
remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right
into your project so you have full control over them. All of the commands except eject will still work, but they will
point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you
shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't
customize it when you are ready for it.
