Jest Mock

jest.mock('@kesha-antonov/react-native-action-cable', () => ({
  ActionCable: {
    createConsumer: jest.fn(() => ({
      subscriptions: {
        create: jest.fn(() => ({
          on: jest.fn().mockReturnThis(),
          removeListener: jest.fn().mockReturnThis(),
          perform: jest.fn(),
          unsubscribe: jest.fn(),
        })),
      },
      connection: {
        isActive: jest.fn(() => true),
        isOpen: jest.fn(() => true),
      },
      disconnect: jest.fn(),
    })),
  },
  Cable: jest.fn(() => ({
    channels: {},
    channel: jest.fn(),
    setChannel: jest.fn(),
  })),
}))

See examples/testing for complete testing examples.

Testing this library

The library itself is covered by a Jest suite in __tests__, which drives the real connection code against a WebSocket double that behaves like a Rails ActionCable server:

yarn test           # run the suite
yarn test:coverage  # run it with a coverage report
yarn typecheck      # type-check the library and the tests
