What factors distinguish Nightwatch.js from Protractor in terms of functionality and performance?

Can you outline the variances between Nightwatch.js and Protractor? What benefits does each offer when used in an Angular project?

Nightwatch.js compared to Protractor

Answer №1

When it comes to AngularJS projects, the clear choice is Protractor:

  • Designed specifically for angular apps (but also works with non-angular apps)
    • Utilizes angular-specific locator strategies like by.model, by.repeater, and more
    • Waits for angular to fully load during page initialization (sync)
  • Actively maintained and improved primarily by Google developers in close collaboration with the angular team - ensuring alignment with angular release cycles and updates

Answer №2

While the top answer provided some insights, there are additional differences worth mentioning.

One significant difference for me is that protractor currently does not support phantomJS (http://www.protractortest.org/#/browser-setup#setting-up-phantomjs). This limitation led me to consider setting up a windows VM for running tests when integrating automation into our CI system.

Here are some advantages of nightwatch:

  • Automated asserts.
  • Clean console output easy to share.
  • Automatic test report generation saved in a /reports directory.

On the other hand, here are the pros of using protractor:

  • The powerful angular-specific locators it supports can significantly contribute to creating stable tests.
  • The functionality of WaitForAngular is also quite beneficial.

EDIT: Since writing this comment, our team has transitioned to using cypress.io and we couldn't be happier with the switch. For those considering test frameworks, I highly recommend exploring cypress.io:
