🧪 Add tests for joinUrls logic in utils.ts

[sunnylqm]

🧪 Testing Improvement: joinUrls logic

🎯 What: The testing gap addressed
The joinUrls logic inside src/utils.ts had no unit tests covering its simple but important mapping behavior for constructing update URLs. I have added bun:test unit tests specifically for joinUrls and introduced test setup configurations to ensure the required mocks (like react-native platform details and i18n translations) are safely provided during the test execution.

📊 Coverage: What scenarios are now tested

• Valid paths and fileName combinations prepending https://
• Missing fileName (returning undefined)
• Empty array provided for paths (returning empty array)

✨ Result: The improvement in test coverage
The code is thoroughly covered using bun test, confirming there's a safety net when anyone refactors the joinUrls utility. Run the unit tests suite exclusively via bun test src/.

📝 Walkthrough

Walkthrough

The changes add test infrastructure to the project, including Bun configuration for test preloading, a test setup module that mocks external dependencies, and unit tests for a joinUrls utility function.

Changes

Cohort / File(s)	Summary
Test Configuration bunfig.toml	Adds test.preload configuration to preload setup module before tests run.
Test Setup Mocks src/__tests__/setup.ts	Creates module mocks for react-native (Platform.OS = 'ios') and i18n (default t function returning input key).
Unit Tests src/__tests__/utils.test.ts	Implements test suite for joinUrls utility with three test cases covering undefined fileName, empty paths, and URL construction with multiple paths and fileName.

Poem

🐰 A test setup script, so neat and bright,
With mocks for modules working just right,
joinUrls tested from path to domain,
Our code now robust, without any strain!
hops away with a test report 📋✨

src/__tests__/utils.test.ts (1)

1-17: Remove duplicated module mocks from this test file.

These mocks already exist in the preloaded src/__tests__/setup.ts; keeping both copies increases drift risk and maintenance overhead.

♻️ Proposed refactor

-import { describe, expect, test, mock } from 'bun:test';
+import { describe, expect, test } from 'bun:test';
 
-mock.module('react-native', () => {
-  return {
-    Platform: {
-      OS: 'ios',
-    },
-  };
-});
-
-mock.module('../i18n', () => {
-  return {
-    default: {
-      t: (key: string) => key,
-    },
-  };
-});
-
 import { joinUrls } from '../utils';
