javascript-testing-best-practices
📗🌐 🚢 Comprehensive and exhaustive JavaScript & Node.js testing best practices (April 2024)
-
In this article, we explore logging best practices that are largely tool-agnostic, but we'll demonstrate them using PactumJS, a powerful and extensible API testing tool, along with Mocha, a popular JavaScript test framework. For logging, we’ll use Pino, one of the fastest and most reliable structured loggers for Node.js.

Project mention: JavaScript package manager - How to fix Cannot find module 'cheerio' error with Enzyme in Yarn 1 projects | dev.to | 2025-06-11
Cheerio Update to 1.0.0 is breaking Enzyme 3.11.0 for Node < 18.17.0 #2606
-
react-testing-library
🐐 Simple and complete React DOM testing utilities that encourage good testing practices.
React Testing Library tests React components by simulating how users interact with them, rather than focusing on the implementation details. This library prioritizes the principle of testing components as users interact with them, making tests more resilient to code changes. By avoiding reliance on the internals of the components, it ensures that your tests remain focused on functionality and user experience. It integrates well with Jest and provides utilities to query, simulate interactions, and validate DOM updates effectively.
-
Jasmine is a standalone JavaScript testing framework that emphasizes simplicity and ease of use. It provides all necessary tools for writing tests without requiring additional libraries. Jasmine’s BDD syntax makes it easy to describe and structure tests in a way that’s easy to understand. While it doesn’t come with advanced features like mocking or spying, its lightweight nature and straightforward approach make it a good option for small to medium-sized React projects.

artillery
The complete load testing platform. Everything you need for production-grade load tests. Serverless & distributed. Load test with Playwright. Load test HTTP APIs, GraphQL, WebSocket, and more. Use any Node.js module.
My simple ab tests? Yeah, they were totally not enough! For high-stakes events like flash sales, really thorough load testing is just non-negotiable. Period. Now, I make sure to incorporate more robust tools like k6 or Artillery into my pre-launch checklist for any client project that’s expecting a lot of traffic. These tools can simulate thousands of concurrent users, which is awesome for spotting bottlenecks *before* they ever hit production. Trust me, it's worth every bit of effort!

We usually run Angular tests through the cli ng test which picks the default config from /node_modules/@angular-devkit/build-angular/src/webpack/plugins/karma/karma.js, runs the tests in the project/workspace context, shows the execution log in the terminal and generates coverage using istanbul.js based on custom config we defined.
