Unlock the Power of JavaScript Testing Frameworks
As we step into a new decade, the world of JavaScript is more vibrant than ever. With over 21,000 developers sharing their insights in the 2019 State of JavaScript report, we’re about to uncover the top testing frameworks that will dominate the scene in 2020.
The State of JavaScript: A Comprehensive Survey
Every year, the State of JS survey provides a snapshot of the JavaScript ecosystem, covering everything from frontend web development frameworks to databases, state management, and more. This year’s report is particularly exciting, with a record-breaking 21,000+ developer responses.
The Most In-Demand Testing Tools of 2019
So, what are the most sought-after testing tools among JavaScript developers? Let’s dive into the top frameworks that made the cut:
Jest: The Zero-Configuration Champion
Built and maintained by Facebook, Jest is a zero-configuration JavaScript testing framework that’s easy to use and has a staggering acceptance rate among developers. With over 1.5 million projects using Jest, its retention rate has skyrocketed from 39% to 61% in just 12 months.
Mocha: The Flexible Favorite
Mocha has been a staple in the JavaScript testing community for years, offering a massive ecosystem and excellent documentation. Its flexibility and openness to extensions have earned it a spot in over 900,000 projects, with a retention rate growth from 39% to 42% in the last year.
Storybook: The UI Component Powerhouse
Storybook is a development environment for UI components that allows for interactive testing and development. Its retention rate has doubled from 15% to 32% in 12 months, with a significant increase in interest from developers.
Cypress: The Fast and Reliable Contender
Cypress is a fast and reliable JavaScript testing tool that injects tests into web applications. With a retention rate of 23% and an interest rate of 28%, Cypress is a force to be reckoned with in the testing framework landscape.
Enzyme: The React Testing Utility
Enzyme is a JavaScript testing utility for React that makes it easier to test components’ output. Its retention rate has grown from 20% to 23% in the last year, with a significant bridge of the awareness gap.
Ava: The Concise Test Runner
Ava is a test runner for Node.js with a concise API and detailed error output. Its retention rate has grown to 5%, with a slight decrease in awareness among developers.
Jasmine: The BDD Testing Framework
Jasmine is a Behavior Driven Development testing framework that’s suited for websites, Node.js projects, or anywhere JavaScript can run. Its retention rate has slightly increased in the past 12 months, but there’s still a growing gap in awareness.
Puppeteer: The High-Level API Champion
Built by Google, Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium. Its retention rate stands at 24.3%, with an interest rate of 24%. Despite being used by over 55,000 projects, there’s still a need for more awareness.
The Future of JavaScript Testing
As we look ahead to 2020, it’s clear that Jest is leading the market, with over 96% of its users being return users. However, the rise of new entrants like Puppeteer and Cypress is exciting news for developers. With the complexity of frontends increasing, it’s more important than ever to have the right testing tools in your arsenal.
