Common Patterns

Load Scenario in Tests

import { readScenario } from '@mockmaster/cli'
import { createReplayHandler } from '@mockmaster/msw-adapter'
 
const scenario = await readScenario('./scenarios', 'user-api')
const handler = createReplayHandler(scenario)
 
const response = handler({ method: 'GET', path: '/users' })

Setup in beforeEach

describe('API Tests', () => {
  let handler: ReturnType<typeof createReplayHandler>
 
  beforeEach(async () => {
    const scenario = await readScenario('./scenarios', 'user-api')
    handler = createReplayHandler(scenario)
  })
 
  it('fetches users', () => {
    const response = handler({ method: 'GET', path: '/users' })
    expect(response.status).toBe(200)
  })
})
