@quenetiq/testing

Mock GraphQL backend for unit testing Quenetiq queries and mutations.

Install

npm install @quenetiq/testing

Quick Start

import { provideQuenetiqTesting, MockGraphqlService } from '@quenetiq/testing';

TestBed.configureTestingModule({
  providers: [provideQuenetiqTesting()],
});

it('mocks a query', () => {
  const mock = TestBed.inject(MockGraphqlService);
  mock.when(
    gql`query Todos { todos { id } }`,
    { data: { todos: [{ id: '1' }] } },
  );

  const graphql = TestBed.inject(GraphqlService);
  graphql.query(gql`query Todos { todos { id } }`).subscribe(result => {
    expect(result.status).toBe('success');
  });
});

API

| Export | Description | |--------|-------------| | MockGraphqlService | FIFO mock — when(request, result) registers responses | | provideQuenetiqTesting() | Provider array for TestBed | | MockedRequest | { query: string; variables?: Record<string, unknown> } | | MockedResponse | { data?: T; errors?: { message: string }[] } |

Usage

Responses are consumed FIFO. If no mock is registered for a request, the service returns { status: 'error', error: 'No mock response configured' }.
