Issue Checklist

Please confirm the following:

[x] I have upgraded to the latest
[x] I have the read the FAQs in the Readme
[x] I have triple checked, that there are no unhandled promises in my code and have read the section on intermittent test failures
[x] I have set my log level to debug and attached a log file showing the complete request/response cycle
[ ] For bonus points and virtual high fives, I have created a reproduceable git repository (see below) to illustrate the problem

Expected behaviour

verifyProvider() should throw an error if neither pactUrl nor pactBrokerUrl is specified.

Actual behaviour

If no pact source is specified, i.e. none of the pactBrokerUrl or pactUrl arguments are specified, the provider test passes, which is not the expected behavior.

Steps to reproduce

Example:

const {Verifier} = require('@pact-foundation/pact');
describe('Testing pactVerifier', () => {
  it('Test1',  () => {
    let opts = {
      providerBaseUrl: 'http://localhost:8888',
      provider: 'provider-service',
      // pactBrokerUrl: 'http://my-pact-broker.com',
      // pactUrls: [__dirname + '/pacts/pact1.json'],
      logLevel: 'debug',
      verbose: true,
    };
    return new Verifier(opts).verifyProvider();
  });
});
