A comprehensive testing module for Elysia-Nest applications, providing:

• Testing module builder for isolated unit tests

• Factory-based dependency injection
• Support for all provider types (value, class, factory)

Example

Quick start:

import { Test } from '@nestelia/testing';

describe('MyService', () => {
  let moduleRef: TestingModule;
  let service: MyService;

  beforeAll(async () => {
    moduleRef = await Test.createTestingModule({
      providers: [MyService, DatabaseService],
    })
      .overrideProvider(DatabaseService)
      .useValue({ query: () => [] })
      .compile();

    service = moduleRef.get(MyService);
  });

  it('should work', () => {
    expect(service).toBeDefined();
  });
});
