[Question] how to capture client instance before any steps have been executed

[pendenaor]

I'm currently migrating my bdd test (based on the cucumber example) and i want to create some page urls with url property set in global test settings, eg:

const pageUrls = {
  'application page': `${url}/`,
  'login page': `${url}/login`,
  'dashboard page': `${url}/main/dashboard`
}

[mucsi96]

Why you don’t create a simple node module with these constants and import it where needed?

[mucsi96]

You can add the url also to this module. And import it in nightwatch configuration

[pendenaor]

I have some troubles to understand what to do.
Below a sample of my code :

import { client } from 'nightwatch-api';
import { defineStep } from 'cucumber';

const { url } = client.globals; // <= BOOM!

const pageNames = {
  'application page': `${url}/`,
  'login page': `${url}/login`,
  'dashboard page': `${url}/main/dashboard`
}

defineStep(/^I (?:browse|open|visit).*? `(.*?)`$/, async pageName => {
  console.log(pageNames[pageName])
});

When i run this code, it raises an exception

Error: Nightwatch client is not ready.
              Looks like function "createSession" did not succeed or was not called yet.

May be i've to tweak test/support/setup.js

import { setDefaultTimeout, AfterAll, BeforeAll} from 'cucumber'
import { createSession, closeSession } from 'nightwatch-api';
import { client } from 'nightwatch-api'; // <== add this

setDefaultTimeout(60000);

BeforeAll(async () => {
  await createSession('default');
  // inject here client globals and calculated url into World (=this) ?
});

AfterAll(async () => {
  await closeSession();
});

I see. Maybe its a bug. Will try to investigate. Until this is resolved I suggest not using nightwatch globals. Just creating an node module for that.And using it in page objects, steps and nightwatch configuration as well. Is it fine for you?

[pendenaor]

ok, thanks for your time. And thanks for nightwatch-api 👍

[pratyush23]

I am also facing the same issue while running cucumber tests using nightwatch-api. Can we please get a solution for this. Thanks

[spnraju]

Hi @pendenaor and @pratyush23 , are you still facing this issue? If yes, could you point me to a repo with sample project with similar config?

[mucsi96]

Closing due to lack of activity. Feel free to reopen if the issue still exist

[hardeep-bit]

@spnraju @mucsi96 i am facing the same issue
Looks like function "createSession" did not succeed or was not called yet.
( i am trying to attach vscode debugger with nightwatch test case with jest )

[KatiKop]

@mucsi96 I am facing this issue, too.
My tests need the client.globals to know where they have to start. As an example I am checking the currently used .env File in my nightwatch.conf. Afterwards I set the URL dynamically.

I have also to distinguish between some things and therefor I am using boolean values.

Example for my config:

globals: {
                url: isStagingEnvironment ? 'www.example.com' : 'http://localhost',
                apiUrlApplicant: process.env.URL_APPLICANT,
                apiTokenApplicant: process.env.API_TOKEN,
                useNetworkStubs,
                isNotMocked,
                isStagingEnvironment,
            },

Example for a using in my step files:

if (client.globals.isStagingEnvironment) {
        client.expect.element(_SELECTOR_).to.be.visible.before(DEFAULT_WAIT_IN_MS);
    }

Example for a using in my helper files:

const { client } = require('nightwatch-cucumber');

const { url } = client.globals;

module.exports = {
    'applications page': `${url}/.../...`,
....

Hi @mucsi96

First, thanks a lot for this new package API. Looks interesting.
I don't know if my problem is similar but after did the configurations I could not run steps files when I am using page object model.

I am trying to update my framework test from the old "Nightwatch-Cucumber (deprecated)" to this new "Nightwatch-api".
After run my step test, I am facing the issue:

Error: Nightwatch client is not ready.
              Looks like function "createSession" did not succeed or was not called yet.

Basically, this was working fine before in old "Nightwatch-Cucumber (deprecated)" but in this new api is not running:

This is the code that I am using in my step file:

const { client } = require('nightwatch-api');
const { Given, Then, When } = require('cucumber');
var core = require('../../../../../pages/core');
core(client).loginRequired();

Is there something that I am not considering to point correctly to my function?

Thanks in advance for your help!

[spnraju]

Hi @gornelex , thanks for reaching out. I see that you are facing issues in migration. Please note that nightwatch-api is a lot different than that of nightwatch-cucumber. Please follow the examples provided in the repo. if you still face the issue, an example setup will help in understanding it better. Please let us know.
