Subject: [PATCH 1/8] test(theme): Add robust Jest/TS support and tests for
 theme components

- Add tests for ArrayBrackets, SkeletonLoader, StatusCodes, and ApiLogo components
- Mock Docusaurus and theme modules (@theme/ApiTabs, @theme/Details, etc.) via __mocks__ and manual Jest config mappings
- Add @ts-ignore to theme imports in StatusCodes to bypass TS2307 errors
- Add custom type declarations for theme mocks (src/theme-modules.d.ts) and update tsconfig.json for global recognition
- Update jest.config.js for explicit moduleNameMapper entries and jsdom environment
- Add setupTests.d.ts for jest-dom matchers and global test types
- Ensure all new and updated files are included for proper TypeScript and Jest operation

This enables reliable, isolated testing of theme components in docusaurus-theme-openapi-docs.

- Ensure both setupFilesAfterEnv entries are loaded in Jest config
- Remove redundant test file mocks
- Add TESTING.md for contributor guidance
- Re-add // @ts-nocheck to ApiTabs source for robust Docusaurus TS support

+# Testing Docusaurus Theme Components
+
+This project uses Jest and Testing Library to test custom Docusaurus theme components. The following conventions and workarounds are in place to ensure tests run smoothly in a Docusaurus monorepo environment:
+
+## Global Test Mocks
+
+- **Browser APIs:**
+  - `ResizeObserver` and other browser-only globals are mocked in [`setupTests.ts`](./setupTests.ts), which is loaded automatically for all tests via Jest config.
+- **Docusaurus Theme/Internal Modules:**
+  - Manual mocks are provided in the [`__mocks__`](./__mocks__) directory for imports like `@docusaurus/theme-common/internal`, `@theme/Heading`, etc.
+  - If you add new components that import other Docusaurus internals, add or extend mocks in this directory.
+
+## TypeScript Workarounds
+
+- Some files (such as those importing `@docusaurus/theme-common/internal`) require `// @ts-nocheck` at the top. This is necessary because TypeScript cannot resolve these modules outside of a full Docusaurus context. This is a common and accepted workaround in plugin/theme projects.
+- If you encounter new TS errors related to Docusaurus internals, prefer targeted type declarations in `global.d.ts` or `theme-modules.d.ts`, but use `// @ts-nocheck` when necessary to unblock tests.
+
+## Running Tests
+
+```sh
+yarn test
+```
+
+## Best Practices
+
+- Keep mocks minimal—only mock what is required for your test to pass.
+- Prefer global setup for browser APIs and repeated mocks.
+- Document any new workarounds or test patterns in this file for future contributors.
+
+---
+
+For more details, see the comments in `setupTests.ts`, `jest.config.js`, and the `__mocks__` directory.

+## Limitations: Testing Deeply Integrated Theme Components
+
+Some Docusaurus theme components—such as `ApiItem`—are tightly coupled to Docusaurus internals, context providers, and plugin APIs. As a result, these components cannot be meaningfully unit tested in isolation using Jest and Testing Library, even with extensive mocks or stubs. Attempts to do so will result in missing module errors or require disabling significant portions of the component, defeating the purpose of the test.
+
+**Recommended Approach:**
+
+- For these components, use integration or end-to-end (E2E) testing in a real Docusaurus site instance (e.g., with Playwright, Cypress, or Puppeteer).
+- Focus unit tests on pure functions and small subcomponents that do not require Docusaurus context.
+- Document these limitations for future contributors.
+
+See this section if you encounter errors related to missing Docusaurus modules when testing theme components.
