Codacy vs Jest: What are the differences?

What is Codacy? Automated Code Review. Codacy is an automated code review tool for Scala, Java, Ruby, JavaScript, PHP, Python, CoffeeScript and CSS. It's continuous static analysis without the hassle. Save time in Code Reviews. Tackle your technical debt.

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

Codacy belongs to "Code Review" category of the tech stack, while Jest can be primarily classified under "Javascript Testing Framework".

Some of the features offered by Codacy are:

Monitoring of Technical Debt
Automated Code Review
New and Fixed Issues per commit

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

"Automated code review" is the primary reason why developers consider Codacy 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.

Airbnb, Facebook, and Instagram are some of the popular companies that use Jest, whereas Codacy is used by Codacy, DocEngage, and InstaGIS. Jest has a broader approval, being mentioned in 263 company stacks & 150 developers stacks; compared to Codacy, which is listed in 44 company stacks and 23 developer stacks.

Cypress

Jest

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.

What are some alternatives to Jest, Codacy?

Mocha

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.

Code Climate

After each Git push, Code Climate analyzes your code for complexity, duplication, and common smells to determine changes in quality and surface technical debt hotspots.

Jasmine

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

Phabricator

Phabricator is a collection of open source web applications that help software companies build better software.

Cypress

Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

PullReview

PullReview helps Ruby and Rails developers to develop new features cleanly, on-time, and with confidence by automatically reviewing their code.

Gerrit Code Review

Gerrit is a self-hosted pre-commit code review tool. It serves as a Git hosting server with option to comment incoming changes. It is highly configurable and extensible with default guarding policies, webhooks, project access control and more.

SonarQube

SonarQube provides an overview of the overall health of your source code and even more importantly, it highlights issues found on new code. With a Quality Gate set on your project, you will simply fix the Leak and start mechanically improving.

CodeceptJS

It is a modern end to end testing framework with a special BDD-style syntax. The test is written as a linear scenario of user's action on a site. Each test is described inside a Scenario function with I object passed into it.

RuboCop

RuboCop is a Ruby static code analyzer. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide.
