Pact exited with code 1

I'm trying to execute some tests with Pact library and I'm getting some errors. Here is the test configuration:

const path = require('path');
const Pact = require('pact');
const expect = require('expect.js');
const config = require('../../../src/server/config');
const service = require('../../../src/routes/interactions/interactions.service');

describe('@component/interactions tests', () => {
    const url = 'http://localhost';
    const port = 8989;

    const provider = Pact({
        port: port,
        log: path.resolve(process.cwd(), 'test/component/interactions/log/interactions-pact.log'),
        dir: path.resolve(process.cwd(), 'test/component/interactions/pacts'),
        spec: 2,
        consumer: 'cx_issue',
        provider: 'interaction',
        // logLevel: 'WARN'
    });

    config.settingsToExport.INTERACTION_URL = `${url}:${port}`;

    before(done => {
        provider.setup()
            .then(() => {
                done();
            })
            .catch(err => {
                done(err);
            });
    });

    after(done => {
        provider.finalize()
            .then(() => {
                done();
            })
            .catch(err => {
                done(err);
            });
    });

    describe('#createInteraction', () => {
        before(done => {
            const INTERACTION_BODY = {
                contact: 'contact1'
            };
            const TERM = {
                generate: '0dae5b93-9451-4b08-b7bb-f0b944fbcdf2',
                matcher: '^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$'
            };

            const pactInteractionCreate = {
                state: 'Creates a new interaction',
                uponReceiving: 'a new interaction is created successfully',
                withRequest: {
                    method: 'POST',
                    path: '/interactions',
                    body: INTERACTION_BODY
                },

                    body: {
                        id: Pact.Matchers.term(TERM)
                    }
                }
            };

            const promises = [
                provider.addInteraction(pactInteractionCreate)
            ];
            Promise.all(promises)
                .then(() => {
                    done();
                });
        });

        it('/api/interactions POST', done => {

            const interaction = {
                contact: 'The xx'
            };

            service.createInteraction(interaction)
                .then(response => {
                    expect(response.id).to.be.equal(TERM.generate);
                    done();
                })
                .catch(done);
        });
    });
});

This is my package.json file content, with all dependencies I've installed:

  "name": "issueAPI",
  "version": "1.0.0",
  "private": true,
  "main": "./src/index.js",

    "pact": "^2.3.3",
    "sinon": "^2.3.8",
    "supertest": "^3.0.0"
  }
}

And this is the error I get: enter image description here

Basically, right now I don't mind at all if the tests are well or not. The main problem right now is that the pact mock server is not being started.

The weird thing here is that I have other project where the pact tests run properly. I've moved the service I want to test from the project where is failing to the one which executes those tests fine, and it is working (at least the pact mock server is launched). The dependencies in this other project are almost the same as the problemathic project:

"dependencies": {
    "ajv": "^4.11.3",
    "body-parser": "^1.16.1",
    "dotenv": "^4.0.0",
    "express": "^4.14.0",
    "jsonwebtoken": "^7.4.1",
    "jwt-simple": "^0.5.1",
    "morgan": "^1.8.1",
    "mustache-express": "^1.2.4",
    "node-env-file": "^0.1.8",
    "request": "^2.79.0",
    "when": "^3.7.8"
  },
  "devDependencies": {
    "@pact-foundation/pact-node": "^4.8.3",
    "eslint": "^3.17.1",
    "eslint-config-node": "^1.6.0",
    "expect.js": "^0.3.1",
    "mocha": "^3.2.0",
    "nodemon": "^1.11.0",
    "pact": "^2.3.3",
    "sinon": "^1.17.7",
    "supertest": "^3.0.0",
    "nock": "^9.0.13"
  }

What's going on with this situation?

EDIT: I've launched the pact tests with DEBUG flag and this is the log generated: enter image description here enter image description here

Solution

  • It looks like the server is unable to start up correctly, judging by the exit code of 1. This could be a port conflict on port 8989, so that's worth checking.

    It could be related to https://github.com/pact-foundation/pact-js/issues/64 (Windows file paths limited in length).

    Could you please enable DEBUG logging with logLevel: 'DEBUG' and note what it outputs, and also share any *.log file. It could be an argument is not being correctly formatted when starting the server.

    As you note, it is unable to start the underlying Ruby process so we need to get to the bottom of that.
