@relaycorp/ws-mock

Mock client and server to unit test the NPM package ws.

Install

npm install @relaycorp/ws-mock

Using the mock client

You should initialise MockClient by passing the WebSocket server to be tested and then call client.connect() to initiate the connection. From that point you can interact with the server. For example:

  test('Challenge should be sent as soon as client connects', async () => {
    const client = new MockClient(wsServer);
    await client.connect();

    const challengeSerialized = await client.receive();
    expect(challengeSerialized).toBeInstanceOf(ArrayBuffer);
  });
