Concourse vs Mocha: What are the differences?
Developers describe Concourse as "Pipeline-based CI system written in Go". Concourse's principles reduce the risk of switching to and from Concourse, by encouraging practices that decouple your project from your CI's little details, and keeping all configuration in declarative files that can be checked into version control. On the other hand, Mocha is detailed as "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.
Concourse and Mocha are primarily classified as "Continuous Integration" and "Javascript Testing Framework" tools respectively.
"Real pipelines" is the top reason why over 8 developers like Concourse, while over 130 developers mention "Open source" as the leading cause for choosing Mocha.
Concourse and Mocha are both open source tools. Mocha with 18K GitHub stars and 2.43K forks on GitHub appears to be more popular than Concourse with 3.92K GitHub stars and 472 GitHub forks.
Asana, Intuit, and Coursera are some of the popular companies that use Mocha, whereas Concourse is used by Starbucks, DigitalOcean, and HelloFresh. Mocha has a broader approval, being mentioned in 397 company stacks & 268 developers stacks; compared to Concourse, which is listed in 18 company stacks and 17 developer stacks.
I'm planning to setup complete CD-CD setup for spark and python application which we are going to deploy in aws lambda and EMR Cluster. Which tool would be best one to choose. Since my company is trying to adopt to concourse i would like to understand what are the lack of capabilities concourse have . Thanks in advance !
I would definetly recommend Concourse to you, as it is one of the most advanced modern methods of making CI/CD while Jenkins is an old monolithic dinosaur. Concourse itself is cloudnative and containerbased which helps you to build simple, high-performance and scalable CI/CD pipelines. In my opinion, the only lack of skills you have with Concourse is your own knowledge of how to build pipelines and automate things. Technincally there is no lack, i would even say you can extend it way more easily. But as a Con it is more easy to interact with Jenkins if you are only used to UIs. Concourse needs someone which is capable of using CLIs.
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.
