🧪 [test] Add unit tests for formatArtifactOutput#26
Conversation
- Created `extension/content.test.js` to test `formatArtifactOutput`. - Used Node's `vm` module to securely load and evaluate `extension/content.js` in a mocked browser context, allowing us to extract and test the unexported pure function. - Added test cases covering happy path with valid props and content, edge cases for empty content, and edge cases for empty props. - Fixed unrelated broken mock payloads and responses in app `vitest` unit tests.

Code Review
This pull request refactors the chat API tests by removing obsolete console spies and updating test data to match revised validation requirements. It also introduces a new test file for the extension content script. The review feedback recommends aligning the new test file with the project's existing Vitest and ESM standards to avoid maintainability issues and suggests removing an empty afterEach block in the API tests.

This new test file introduces several consistency and maintainability issues:
- Test Runner Inconsistency: The project already uses
vitest. Addingnode:testintroduces a second testing framework, which complicates the CI/CD pipeline and developer workflow. - Module System Mismatch: The file uses
require(CommonJS), whereas the rest of the project usesimport(ESM). If the project is configured with"type": "module"inpackage.json, this file will fail to execute with aReferenceError: require is not defined. - Fragile File Loading:
fs.readFileSync('./extension/content.js', ...)uses a relative path that depends on the process's current working directory. This makes the test fragile if run from different locations.
Recommendation: Rewrite this test using vitest and ES modules. You can still use the vm module within Vitest if necessary, or better yet, use Vitest's global mocking capabilities (e.g., vi.stubGlobal).

The afterEach block is now empty and should be removed to maintain code cleanliness.

🎯 What: Added missing unit tests for the pure function
formatArtifactOutputinextension/content.js.📊 Coverage: Covered formatting with valid props and content, handling empty content gracefully, and handling empty props. Also addressed existing unrelated broken tests in
app/.✨ Result: Improved test coverage and reliability of the browser extension's core formatting functions. Allowed testing of unexported functions via the node
vmmodule without modifying production extension code.PR created automatically by Jules for task 11257775262114886320 started by @SSoggyTacoMan
