Hi, I am trying to write a consumer test for my microservice. I am trying to generate contract to two APIs ie. create Profile (POST) and get Profile (GET). My Post interaction is always successful but GET API interaction always fails. I am not very sure what i am doing wrong. Need some guidance from the community member.

const path = require('path');
const { PactV3, SpecificationVersion } = require('@pact-foundation/pact');
const { like, regex } = require('@pact-foundation/pact').Matchers;
const axios = require('axios');
const create_person = require('../data/create_person.json');
const create_person_response = require('../data/create_person_resonse.json');
const get_person_by_id_response = require('../data/get_person_by_id_response.json');
const PORT = 8090;
axios.defaults.timeout = 60000;
const provider = new PactV3({
    consumer: 'ProfileConsumer2',
    provider: 'ProfileProvider1',
    port: PORT,
    spec: SpecificationVersion.SPECIFICATION_VERSION_V2,
    log: path.resolve(process.cwd(), 'logs', 'pact.log'),
    dir: path.resolve(process.cwd(), 'pacts'),
    logLevel: 'debug',

});


function createProfile() {
    return <http://axios.post|axios.post>(`<http://localhost>:${PORT}/v2/profile/person/`, create_person, {
        headers: { 'Content-Type': 'application/json' },
    });
}

function findProfile() {
    return axios.get(`<http://localhost>:${PORT}/v2/profile/find`, {
        params: {
            ids: '10000017',
            scope: 'full',
        },
        headers: { 'Content-Type': 'application/json' },
    });
}

describe('Contract test for Profile', () => {
    describe('Pact with Profile API', () => {
        it('should create contract for POST API', async () => {
            await provider.addInteraction({
                state: 'Create Profile test',
                uponReceiving: 'a request to create a profile',
                withRequest: {
                    method: 'POST',
                    path: '/v2/profile/person/',
                    headers: { 'Content-Type': 'application/json' },

                },

                    body: create_person_response,
                },
            });

            await provider.executeTest(() => {
                return createProfile().then((result) => {
                    expect(result.status).toBe(201);
                    expect(result.data).toEqual(create_person_response);
                });
            });
        });
    });

    describe('Pact test for GET API', () => {

                    method: 'GET',
                    path: '/v2/profile/find',
                    headers: { 'Content-Type': 'application/json' },
                    query: {
                        ids: '10000017',
                        scope: 'full',
                    },
                },
                willRespondWith: {
                    status: 200,
                    headers: { 'Content-Type': 'application/json' },
                    body: get_person_by_id_response,
                },
            });

            await provider.executeTest(() => {
                return findProfile().then((result) => {
                    expect(result.status).toBe(200);
                    expect(result.data).toEqual(get_person_by_id_response);
                });
            });
        });
    });
});

I get below error when i run it

If you only run the GET, does that work?

Let me try with GET Call only

I’m wondering if maybe the advice here might help: https://github.com/pact-foundation/pact-js/issues/1066#issuecomment-1453007940

Only GET call works.

That lends credence to the above theory. The HTTP client is holding onto a connection that is terminated between tests (the mock server will shutdown between tests)

Thanks for the help. I added keep alive =false in the axios request.Also will use dynamic port as best practice.

no probs
