Compass vs Protractor: What are the differences?

  1. Syntax: One key difference between Compass and Protractor is the syntax they use to write test scripts. Compass uses SCSS syntax, while Protractor utilizes JavaScript to write test scripts.
  2. Compatibility: Compass is primarily used for styling and compiling Sass files, whereas Protractor is specifically designed for end-to-end testing of AngularJS applications.
  3. Framework: Compass is a CSS authoring framework, providing a set of useful tools and functions for styling, whereas Protractor is a testing framework specifically built for AngularJS applications, making it easier to write and execute tests for AngularJS applications.
  4. Execution Environment: Compass runs on the Ruby platform, whereas Protractor relies on Node.js for its execution environment.
  5. Purpose: The main purpose of Compass is to make CSS authoring easier and more efficient, while Protractor is focused on automating testing processes for AngularJS applications.
  6. Community Support: Protractor has a larger and more active community compared to Compass, providing better resources and support for its users.

In Summary, Compass and Protractor differ in syntax, compatibility, framework, execution environment, purpose, and community support.

ProtractorProtractor

In the company I will be building test automation framework and my new company develops apps mainly using AngularJS/TypeScript. I was planning to build Protractor-Jasmine framework but a friend of mine told me about Cypress and heard that its users are very satisfied with it. I am trying to understand the capabilities of Cypress and as the final goal to differentiate these two tools. Can anyone advice me on this in a nutshell pls...

I've used both Protractor and Cypress extensively. Cypress is the easier and more reliable tool, whereas Protractor is the more powerful tool. Your choice of tool should depend on your specific testing needs. Here are some advantages and disadvantages of each tool:

Cypress advantages:

  • Faster

  • More reliable (tends to throw fewer intermittent false failures)

  • Easier to read code (handles promises gracefully)

Cypress disadvantages:

  • Cannot switch between browser tabs

  • Cannot switch to iFrames

  • Cannot specify clicks or keypresses explicitly as if a real user was interacting

  • Cannot move the mouse to specific co-ordinates

  • Sometimes has trouble switching between different top-level domains, so not good for testing external links

  • Cypress is a newer tool with less extensive documentation and less community support

Protractor advantages:

  • More powerful because it is Selenium-based - it can switch between tabs, it can handle external links to other domains, it can handle iFrames, simulate keypresses and clicks, and move the mouse to specific co-ordinates within the browser.

  • More extensive community support and documentation

Protractor disadvantages:

  • Slower and more brittle - in general there is a higher likelihood of cryptic and/or intermittent errors which may cause your tests to fail even though there is nothing wrong with your application

  • For highly experienced automation engineers, the fundamental "brittle" nature of Selenium can be worked around - it can be reliable but only if you really know what you are doing

  • Less graceful handling of promises - relies on async/await or .then to manage the order of execution. Therefore it is a bit harder to read the code.

  • Harder to set up, and the method of setup impacts its reliability. For example, a hub/node configuration where the selenium jar is on a different physical machine than the browser under test will cause unreliability in your tests. Not everyone knows about this type of thing, so it's common to find Selenium frameworks that are set up poorly.

It's probably better to use Cypress if

  • you're at a smaller company and have a close relationship with developers who can help write hooks or stubs in their code to assist your testing

  • you don't need to do things like switch between tabs or test links to external top-level domains

It's probably better to use Protractor if

  • You might need to switch between tabs or test external links to other domains within the scope of your framework

  • You want to use a more accurate simulation of how a real user interacts with a browser (i.e. click at this location, type these keys)

  • You're at a company where you won't have any support from developers in writing hooks or stubs to make their code more testable in a less powerful framework like Cypress

    What is Compass?

    The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions.

    What is Protractor?

    Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
