What is Chai?

It is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. It has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel.

Chai is a tool in the Testing Frameworks category of a tech stack.

Chai Alternatives & Comparisons

What are some alternatives to Chai?

Jest

Jest

Jest provides you with multiple layers on top of Jasmine.

Mocha

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.

Jasmine

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.

Cypress

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.

SinonJS

SinonJS

It is a really helpful library when you want to unit test your code. It supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.

Protractor

Protractor

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.

Needs advice on code coverage tool in Node.js/ExpressJS with External API Testing Framework

Hello community,

I have a web application with the backend developed using Node.js and Express.js. The backend server is in one directory, and I have a separate API testing framework, made using SuperTest, Mocha, and Chai, in another directory. The testing framework pings the API, retrieves responses, and performs validations.

I'm currently looking for a code coverage tool that can accurately measure the code coverage of my backend code when triggered by the API testing framework. I've tried using Istanbul and NYC with instrumented code, but the results are not as expected.

Could you please recommend a reliable code coverage tool or suggest an approach to effectively measure the code coverage of my Node.js/Express.js backend code in this setup?

Needs adviceonNuxt.jsNuxt.jsTypeScriptTypeScriptES6ES6

For our internal team and collaboration panel we use Nuxt.js (with TypeScript that is transpiled into ES6), Webpack and npm. We enjoy the opinionated nature of Nuxt.js over vanilla Vue.js, as we would end up using all of the components Nuxt.js incorporates anyways and we can adhere to the conventions setup by the Nuxt.js project, which allows us to get better support in case we run into any dead ends. Webpack allows us to create reproducable builds and also debug our application with hot reloads, which greately increased the pace at which we are able to perform and test changes. We also incorporated a lot of testing (ESLint, Chai, Jasmine, Nightwatchjs) into our pipelines and can trigger those jobs through GitLab CI. All packages are fetched through npm, so that we can keep our git repositories slim and are notified of new updates aswell as reported security flaws.
