Mocha vs Selenium: What are the differences?
Mocha: Simple, flexible, fun javascript test framework for node.js & the browser. Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases; Selenium: Web Browser Automation. Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
Mocha belongs to "Javascript Testing Framework" category of the tech stack, while Selenium can be primarily classified under "Browser Testing".
"Open source", "Simple" and "Promise support" are the key factors why developers consider Mocha; whereas "Automates browsers", "Testing" and "Essential tool for running test automation" are the primary reasons why Selenium is favored.
Mocha and Selenium are both open source tools. Mocha with 18K GitHub stars and 2.43K forks on GitHub appears to be more popular than Selenium with 14.7K GitHub stars and 4.92K GitHub forks.
MIT, PedidosYa, and HubSpot are some of the popular companies that use Selenium, whereas Mocha is used by Sellsuki, Onedio, and triGo GmbH. Selenium has a broader approval, being mentioned in 770 company stacks & 425 developers stacks; compared to Mocha, which is listed in 397 company stacks and 268 developer stacks.
we are having one web application developed in Reacts.js. in the application, we have only 4 to 5 pages that we need to test. I am having experience in selenium with java. Please suggets which tool I should use. and why ............................ ............................ .............................
Seleniumwith the help of selenium we can automate react js for functional testing
We use Mocha for our FDA verification testing. It's integrated into Meteor, our upstream web application framework. We like how battle tested it is, its' syntax, its' options of reporters, and countless other features. Most everybody can agree on mocha, and that gets us half-way through our FDA verification and validation (V&V) testing strategy.
