I am planning to test a ReactJS application and wanted to find out what is the best tool out there in the market to carry out end-to-end tests? After doing a little research i found that there are many tools available to test ReactJS applications but what is the best one to use for end-to-end tests?
There is no concept of “best tool” when it comes to automated testing. It all depends on the context of your project and what you want to achieve from the tool.
That means that not only testers can write automated end-to-end tests, but developers can also help when there is not enough time or resource.
Below is a list of test automation tools and frameworks to test ReactJS application:
Nightwatch.js is an easy to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites. It uses the powerful W3C WebDriver API to perform commands and assertions on DOM elements.
Nightmare is a high-level browser automation library from Segment.
Niffy is a perceptual diffing tool built on Nightmare. It helps you detect UI changes and bugs across releases of your web app.
While Jest is popular amongst Facebook developers to write automated tests for ReactJS applications, it has some issues (slow, mocking is confusing). Mocha has become a popular alternative. It’s more painful to set up but may be worth a look. I expect it to become more popular in the future unless Jest overcomes some of those main issues. Seeto get started.
For acceptance testing, you can consider Protector. It’s primarily an Angular tool built on top of Selenium and it comes with a nicer API. Fortunately, it’s possible to configure it to work with React. See. The nice thing about this approach is that this will allow you to test your application against a wide variety of browsers.
Enzyme + Mocha seems to be the best combination to test web applications written in ReactJS. It is relatively easy to learn, even for someone new to ReactJS and Mocha can easily cope with these tools in a short time.
