BrowserStack vs Jest: What are the differences?

What is BrowserStack? Instant access to a lab of 1000+ real mobile and desktop browsers for testing. Live, Web-Based Browser Testing Instant access to all real mobile and desktop browsers. Say goodbye to your lab of devices and virtual machines.

What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.

BrowserStack can be classified as a tool in the "Browser Testing" category, while Jest is grouped under "Javascript Testing Framework".

Some of the features offered by BrowserStack are:

  • Real Device Cloud. Test on a range of physical Android and iOS mobile devices and tablets for the most accurate results
  • 1100+ desktop browsers. Latest versions of IE, Edge, Safari, Chrome, Firefox and more on a range of Windows and OS X platforms on a robust cloud infrastructure
  • Test dev environments. Our Local Testing feature allows you to test development and internal websites seamlessly, without setup or configuration

On the other hand, Jest provides the following key features:

  • Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions
  • Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable
  • Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility

"Multiple browsers" is the primary reason why developers consider BrowserStack over the competitors, whereas "Open source" was stated as the key factor in picking Jest.

Jest is an open source tool with 26.1K GitHub stars and 3.53K GitHub forks. Here's a link to Jest's open source repository on GitHub.

According to the StackShare community, BrowserStack has a broader approval, being mentioned in 572 company stacks & 230 developers stacks; compared to Jest, which is listed in 263 company stacks and 150 developer stacks.

Advice on BrowserStack and Jest

I am looking to purchase one of these tools for Mobile testing for my team. It should support Native, hybrid, and responsive app testing. It should also feature debugging, parallel execution, automation testing/easy integration with automation testing tools like Selenium, and the capability to provide availability of devices specifically for us to use at any time with good speed of performing all these activities.

I have already used Perfecto mobile, and Sauce Labs in my other projects before. I want to know how different or better is AWS Device farm in usage and how advantageous it would be for us to use it over other mentioned tools

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.
