Is it possible to configure my pipeline to run e2e tests in a NestJs project?

I have a NestJs project and I wrote a few e2e tests that send a request to my controllers and check for a response. They run just fine while I have nest running in my localhost. They look like this: 

describe('Health Check', () => 

  {  it('should ping', () => {    

      return request(app)      


        .expect(({ body }) => {        






however, when I try to add a bitbucket pipeline, it always fails when trying to run the e2e tests. It gives this error: connect ECONNREFUSED which seems to mean that it's trying to connect to a localhost. 

What do I need to do in order to get these kind of tests to run? Is it something I need to do with the pipeline or something I should configure in my NestJs app?

My pipeline file currently looks like this: 

image: node:10.15.3

pipelines:  default:   

 - step:        


- node        


- npm install          

- npm run prestart:prod          

- npm test

Hi @Virginia Elizabeth Gil Vásquez

I've tried running few example projects from in Pipelines and they all work just fine. This makes me think that it may be some specific configuration related to your project that requires checking out. Firstly Pipelines runs inside Docker so I would make sure that your project runs inside Docker in your local environment. You would likely encounter the same error and then it's not specific to Pipelines. If that's the case I would try to search for the specific error in relation to NestJS like 

If your project works well inside of Docker but still fails in Pipelines reach out to our support for help
