Bug: Coverage Path Mismatch and Redundant Testing

The workflow has two issues:

1. Bun's coverage output path/format does not match the codecov-action's expected coverage/coverage-final.json, leading to silent upload failures due to fail_ci_if_error: false.
2. Tests are run redundantly twice (bun test and bun test --coverage), wasting CI time, as bun test --coverage already executes all tests.

Bug: Mocking `process.env` in Tests Fails

The beforeEach and afterEach hooks attempt to mock process.env by reassigning the object itself. This approach is unreliable because process.env is a special global object; directly reassigning it may not fully isolate tests or reliably restore the environment. This can lead to environment changes leaking between tests or unexpected failures. A more robust approach involves manipulating individual environment variables.

tests/core/prerequisites.test.ts#L7-L15

gitlift/tests/core/prerequisites.test.ts

Lines 7 to 15 in a7f5f3c

	beforeEach(() => {
	// Reset environment for each test
	process.env = { ...originalEnv };
	});
	afterEach(() => {
	// Restore original environment
	process.env = originalEnv;
	});

tests/core/prerequisites.test.ts:17

• No test covers the successful path where all prerequisites are met; consider adding a test that ensures checkPrerequisites resolves without throwing when environment variables and commands are available.

	it("should throw error when OPENAI_API_KEY is not set", async () => {

tests/README.md:17

• tests/README.md references tests/setup.ts, but there is no setup.ts file in the tests directory; either remove this reference or add the missing setup file.

[nitpick] The test string uses "émojis" and "àccents", which are misspelled in English; consider using "emojis" and "accents".

Suggested change

	const specialText = "🚀 Test with émojis and àccents!";
	expect(theme.primary(specialText)).toContain("🚀 Test with émojis and àccents!");
	expect(theme.success(specialText)).toContain("🚀 Test with émojis and àccents!");

The test writes and deletes a config file in the project root, which may cause side effects; consider using a temporary directory or mocking filesystem interactions to isolate tests.

Suggested change

	const testConfigPath = join(process.cwd(), ".gitliftrc.json");
	import { tmpdir } from "os";
	const testConfigPath = join(tmpdir(), ".gitliftrc.json");

[Copilot]

This test depends on the actual presence of external commands (git, GitHub CLI), making it flaky across environments; consider mocking the command checks or abstracting the dependency to ensure consistent test behavior.
