Programmatical API

Hi,

Thank you for the great lib! If you could point me in the right direction, if there is a programmatical api for the same. I can use execSync but it seems like in most of the CI’, it just hangs. I am using something like this:

const exec = require('sync-exec'); // using lib here because execSync was somtimes acting funny.
const res = exec(`${nwPath} -c ${nwConfig}`, { stdio: [0, 1, 2] });

      if (!res.stderr) {
        return res.status;
      }

      throw res.stderr;

Any ideas?

Thanks a lot 😃

Hi Jeremy!

I think I found the problem. I could reproduce the issue with the following code:

Scenario: Basic site health check
    Given I open the url "https://www.1112.com/"
    Then I expect the title to contain "เดอะ พิซซ่า คอมปะนี 1111"
    Then I again expect the title to contain "เดอะ พิซซ่า คอมปะนี 1112"

this.Then(/^I expect the title to contain "([^"]*)"$/, function (checkTitle) {
    this
      .getTitle(function (t) {
        expect(t.value).to.eql(checkTitle);
      });
  });

  this.Then(/^I again expect the title to contain "([^"]*)"$/, function (checkTitle) {
    this
      .getTitle(function (t) {
        expect(t.value).to.eql(checkTitle);
      });
  });

The first title check step hangs. The problem is that you use chai. chai assertions are throwing errors if the assertion fails. If the chai assertion is in a callback nobody can catch it. This is the bad part of the callbacks. You are allowed only to use nightwatch assertions as they are not thowing errors but adding an extra step to the async task tree what nightwatch is building. So the fixed code look like this:

this.Then(/^I expect the title to contain "([^"]*)"$/, function (checkTitle) {
    this
      .getTitle(function (t) {
        this.assert.equal(t.value, checkTitle);
      });
  });

  this.Then(/^I again expect the title to contain "([^"]*)"$/, function (checkTitle) {
    this
      .getTitle(function (t) {
        this.assert.equal(t.value, checkTitle);
      });
  });
