Problem: Consumer Driven Contract Testing with Pact

Question

Im writing a small programm for a University project. I'd like to test it with the pact framewok. Unfortunately, no Pact.json file is created for me, although there are no errors. My Consumer iss written in Javascript. Below you can see the source code of my javascript file, the console output and my package.json file:

const {Pact} = require('@pact-foundation/pact');
const axios = require('axios');
const path = require('path');


describe('Pact Consumer', () => {
    const provider = new Pact({
        consumer: 'consumer',
        provider: 'producer',
        host:'127.0.0.1',
        port: 1234,
        log: path.resolve(process.cwd(), 'logs', 'pact.log'),
        dir: path.resolve(process.cwd(), 'pacts'),
        logLevel: 'INFO',
    });

    beforeAll(() => provider.setup());
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
    describe('consumer', () => {

        beforeEach
        (() =>

            provider.addInteraction({
                state: "valid date",
                uponReceiving: "a request for JSON data",
                withRequest: {
                    method: "GET",
                    path: "/test",
                    headers: { Accept: "application/json" },
                },
                willRespondWith: {
                    status: 200,
                    headers: { "Content-Type": "application/json" },
                    body:
                        {
                            name: 'Scherr',
                            surname: 'Valerian',
                            age: 28,
                        },

                },


            }),


        );

    });



    describe('test', () => {
        it('should return the correct data', () => {

          return  axios.get('localhost:1234/test').then(response => {
                expect(response[0].name).toBe('Scherr');
                expect(response[0].surname).toBe('Valerian');
                expect(response[0].age).toBe(28);
            }).then(()=> provider.verify())
        });
    });

    afterAll(() => {
        return provider.finalize();
    });
});

Console Output:

   Error: getaddrinfo ENOTFOUND 1234

Actual   :

I am grateful for any help and thanks in advance

Answer 1

I had a similar issue. Setting the cors property on the provider config to true did the job for me.

I didn't seem to have this problem when using node-fetch as opposed to axios.
