## What changes were proposed in this pull request? Add Jest test infrastructure, ESLint test overrides, and shared test harness This PR establishes **how** the dashboard runs and lints unit tests. It does **not** add feature test cases What changes do - **Jest config** (`jest.config.js`): Defines where tests live (`__tests__`, `*.test.*`), `jsdom` environment, `ts-jest`, path aliases (`@components`, `@utils`, etc.), coverage settings, and optional exclusion of governance tests unless `RUN_DEPENDENCY_GOVERNANCE=1`. - **TypeScript for tests** (`tsconfig.test.json`, `tsconfig.build.json` if referenced): Ensures tests type-check consistently with the app’s module settings. - **Babel** (`.babelrc.json` if present): Lets Jest transform JS/ESM dependencies where needed. - **Setup files** (`src/setupTests.ts`, `src/setupTests.simple.ts`): Run before tests (e.g. `@testing-library/jest-dom`, `ResizeObserver` / `matchMedia` shims, shared `jest.mock` for heavy components like table layout). - **Module mocks** (`src/__mocks__/**`): Replace assets (CSS, images), `react-quill-new`, and co-located UI so tests stay fast and deterministic. - **Test utilities** (`src/utils/test-utils.tsx`): Shared `render` helpers (e.g. Redux/Router providers) to avoid duplicating boilerplate. - **ESLint** (`/.eslintrc.cjs`): Adds an **`overrides`** block **only** for tests, mocks, and setup so idiomatic Jest patterns (`require` in factories, hook usage in mocks, etc.) do not fail lint, while **production** `src` keeps stricter rules. - **Package manifest** (`package.json`, `package-lock.json`): Jest/RTL/ts-jest/babel and `npm` scripts (`test`, `test:coverage`, `test:governance`, etc.) so CI and developers run the same commands. - **Governance doc** (`docs/DEPENDENCY_AND_DEPENDABOT_TEST_PLAN.md`): Documents optional dependency/governance workflow (paired with governance **tests** in PR 6). - Without them, tests either **do not run**, **fail to resolve imports**, or **lint incorrectly**; later PRs depend on this foundation **first**. ## How was this patch tested? Manual test, test pass <img width="1105" height="601" alt="Screenshot from 2026-05-14 16-26-37" src="https://github.com/user-attachments/assets/21ceb331-8aa1-4bcc-bda0-ea5c4aa86db3"; /> -- This is an automated message from the Apache Git Service.
