TDD Workflow

Enforce test-driven development: write tests first, implement to pass, then refactor.

RED: Write Failing Tests

Define expected behavior before writing any implementation:

describe('searchMarkets', () => {
  it('returns relevant markets for query', async () => {
    const results = await searchMarkets('election')
    expect(results).toHaveLength(5)
    expect(results[0].relevanceScore).toBeGreaterThan(0.8)
  })
