🧪 A Brief History of Testing (and Why We Cry)

Welcome to copilot-test — a repository where tests go to be written, ignored, and eventually blamed for everything.

🔴 The Five Stages of a Failing Test

1. Denial — "It passed on my machine."
2. Anger — "WHO CHANGED THIS?! git blame... oh. It was me."
3. Bargaining — "What if I just skip this test for now? Just temporarily. For like 3 years."
4. Depression — npm test output: 247 passing, 1 failing. The 1 is always the one you care about.
5. Acceptance — You add // TODO: fix this and open a PR.

🟢 Testing Wisdom

"The best tests are the ones that catch bugs you didn't know you had, written at 2am, that you'll spend the next morning wondering why they exist."

• Unit tests: Tests that prove your function works perfectly in a vacuum that bears no resemblance to production.
• Integration tests: Tests that prove two things work together — until the third thing shows up.
• End-to-end tests: Tests that fail randomly and everyone agrees are "flaky" rather than fixing them.
• Manual testing: Clicking around and hoping for the best. A classic.

🤔 Common Testing Anti-Patterns

// The Classic
test('it works', () => {
  expect(true).toBe(true);
});

// The Optimist
test('nothing will ever go wrong', () => {
  // TODO: write actual test
});

// The Philosopher
test('what even is a bug, really', () => {
  expect(undefined).toBeDefined(); // spoiler: it fails
});

🚀 How to Run Tests

npm test
# output: "found 0 vulnerabilities" (this is a lie)

Good luck. You'll need it.
