I have a variable in protractor.conf.js which is exported within onPrepare() function as: global.myVariable = myVariable, and in spec file I'am trying to use/call it, but it seems that it can't be accessible and isn't available for the spec file.


E/launcher - Error: Error: Cannot find module 'myVariable'

It's being treated as it would be an npm module and can't be found in npm_modules which is correct.

myVariable is actually an object build by a constructor function within protractor.conf.js

How can make it accessible from the spec file?

  • Vincent, would you care to explain in which scenarios you needed to expose a variable globally and access directly in the spec file, as generally it is considered a bad practice . Feb 9, 2018 at 9:49
  • And in case if you have to do it, have it in separate globals.js file and keep config.js light. Feb 9, 2018 at 9:55
  • @VishalAggarwal: Sure, I can add more input and info regarding the background of my question... I'll update my question then.

  • @VishalAggarwal: Sorry for the late answer! here is the background of my question: I do have a test case where a user registers via UI and then gets an email in the inbox. The email contains a registration confirmation link. I'am using a mailListener library and its initialization is being done in protractor.config.js as: var MailListener = require("mail-listener2"); var mailListener = new MailListener({....}). Therefor I have to pass a variable global.mailListener = mailListener to *.spec.ts file and then invoke a method on it.

Issue fixed... solution is:

params: {
    myVariable: function () {
    otherProperty: 'Value'

and this how you can reach in spec files:

browser.params.myVariable or browser.params.otherProperty

with this we can make a variable accessible from protractor.conf.js to spec test files. The following posting was helpful and also the protractor doc where it's explaining the property: params?: any;

  • This works for getPageTimeout , but any other variable e.g serverURL, doesnt work Sep 16, 2021 at 12:04
  • @DhananjaySonar, Could you pls. add more details? It should normally work for any other variable.

I just put a config in my protractor.conf.js with a variable named getPageTimeout and then in my spec.ts I can reference it with browser.getPageTimeout

enter image description here

Wierd though that I had to set the timeout in the Cucumber framework rather than the Jasmine/Protractor framework. I don't quite understand why.
