Example of testing a controller:
import { Test, TestingModule } from '@nestjs/testing';
import { ExampleController } from './example.controller';
import { ExampleService } from './example.service';
describe('ExampleController', () => {
let controller: ExampleController;
beforeEach(async () => {
const module: TestingModule = await Test.createTestingModule({
controllers: [ExampleController],
providers: [
{
provide: ExampleService,
useValue: GrpcMock.createMock<ExampleService>({
method: () => 'Mocked return value',
}),
}
],
}).compile();
controller = module.get<ExampleController>(ExampleController);
});
it('should be defined', () => {
expect(controller).toBeDefined();
});
it('should return mocked value', async () => {
const result = await controller.method();
expect(result).toBe('Mocked return value');
});
});
