prem22k · 2026-02-13T07:03:58Z

This PR adds unit tests for backend/controllers/inspirationController.js. It refactors the controller to use a fileSystem utility wrapper, enabling easier mocking of file operations. It also exports a _resetCache function to allow tests to reset the internal cache state. The new test suite covers various scenarios including cache hits, query filtering, hybrid fallback to scraper, and error handling. Verified with bun test.

📝 Walkthrough

Walkthrough

This PR extracts file system operations into a dedicated utility module and refactors the inspiration controller to use it. A comprehensive test suite for the inspiration controller is added, covering cache serving, filtering, browser-based fallback scraping, and error scenarios.

Changes

Cohort / File(s)	Summary
File System Abstraction `backend/utils/fileSystem.js`, `backend/controllers/inspirationController.js`	New utility module providing `readFile()` and `checkFileExists()` functions. Controller refactored to use the new utility instead of direct fs imports. Added `_resetCache()` public function to clear in-memory cache.
Test Coverage `backend/tests/inspirationController.test.js`	Comprehensive test suite for inspiration controller using Bun test framework. Tests cover cached item serving, query-based filtering, browser fallback scraping thresholds, error handling, and cache behavior with mocked dependencies.

Pull request overview

This PR adds comprehensive unit tests for the inspirationController.js by introducing a fileSystem utility wrapper to enable easier mocking of file operations. The refactoring separates file system concerns from the controller logic, making the code more testable and maintainable. A _resetCache function is also exported to allow tests to reset the internal cache state between test runs.

Changes:

Created fileSystem.js utility wrapper for file operations to enable mocking in tests
Refactored inspirationController.js to use the new fileSystem utility
Added _resetCache function export for test state management
Implemented comprehensive test suite covering cache hits, query filtering, hybrid fallback, and error handling

backend/tests/inspirationController.test.js

+const mockCheckFileExists = mock();
+const mockLaunchBrowser = mock();
+const mockScrapeDribbble = mock();
+const mockCloseBrowser = mock();
+
+mock.module("../utils/fileSystem", () => ({
+  readFile: mockReadFile,
+  checkFileExists: mockCheckFileExists


The mockCheckFileExists function is mocked but never used in the code. The checkFileExists export from fileSystem.js is not used anywhere in the controller. This creates unnecessary test overhead and confusion. Consider removing this mock and the corresponding export from fileSystem.js if it's not needed.

Suggested change

const mockCheckFileExists = mock();

const mockLaunchBrowser = mock();

const mockScrapeDribbble = mock();

const mockCloseBrowser = mock();

mock.module("../utils/fileSystem", () => ({

readFile: mockReadFile,

checkFileExists: mockCheckFileExists

const mockLaunchBrowser = mock();

const mockScrapeDribbble = mock();

const mockCloseBrowser = mock();

mock.module("../utils/fileSystem", () => ({

readFile: mockReadFile

backend/utils/fileSystem.js

+  readFile,
+  checkFileExists
+};


The checkFileExists function is exported but never used in the controller. This export appears to be unnecessary and should be removed to keep the API surface minimal and avoid confusion about which functions are actually needed.

Suggested change

readFile,

checkFileExists

};

readFile

};
