react-testing-library features and specs

  • Focused on user-centric testing
    React Testing Library encourages tests that closely resemble how users interact with an application. This approach makes tests more reliable and meaningful.
  • Reduces coupling to implementation details
    By encouraging developers to interact with components via the DOM, the library minimizes dependencies on component internals, making tests less prone to breaking from refactors.
  • Improved test readability
    Tests written with React Testing Library are generally easier to read and understand because they focus on what the user sees and does, rather than the internal logic of the components.
  • Comprehensive query options
    The library provides a wide range of query methods (e.g., getByText, getByRole), which makes it easy to select elements in ways that resemble how users think.
  • Active community and well-maintained
    React Testing Library has a strong, active community and it's maintained by experienced developers who keep the library up-to-date with React's evolution.

Possible disadvantages of react-testing-library

  • Limited support for non-DOM testing
    The library is heavily focused on DOM interactions, making it less suited for testing non-DOM logic or scenarios that don't involve user interactions.
  • Can be slower
    Tests that involve the DOM can be slower compared to tests that interact directly with component methods and state, which can lead to longer test execution times.
  • Learning curve for traditional testers
    Developers who are used to testing implementation details with other tools (like Enzyme) might find it challenging to adjust to the user-centric approach advocated by React Testing Library.
  • Potential for less granular control
    Because the library encourages testing through the UI, developers might find it harder to test specific, isolated internal behaviors of components that aren't directly visible to users.
  • Dependencies on browser APIs
    The library's reliance on browser APIs means that tests may behave differently in different environments or may require polyfills for certain features, leading to potential inconsistencies.

Enzyme features and specs

  • Shallow Rendering
    Allows you to render a component without its children, which speeds up tests and isolates the component being tested.
  • Rich API
    Provides a comprehensive set of APIs that enable deep rendering, traversing, and manipulating of components, making it flexible and powerful for various testing needs.
  • Compatibility with Mocha and Jest
    Easily integrates with popular testing frameworks like Mocha and Jest, ensuring a smooth setup process.
  • Simulate Events
    Supports simulation of user events such as clicks, enabling more realistic interaction testing.
  • Selector Support
    Allows for selecting and finding elements using CSS selectors or component constructors, making it easier to target specific elements in tests.
  • Active Community
    Has a large and active community, which can be a valuable resource for support, plugins, and best practices.

Possible disadvantages of Enzyme

  • Complex Setup
    The initial setup and configuration can be complex, especially for beginners, requiring additional libraries and configurations.
  • Limited Support for New React Features
    Often lags behind in supporting new React features, such as Hooks or the latest Context API, compared to other testing frameworks.
  • Deprecation Warnings
    Issues with deprecation warnings and updates can arise, causing frustrations during maintenance and upgrades.
  • Performance Overhead
    Can be slower compared to other testing libraries, especially when using deep rendering for large components.
  • Inconsistent API
    Some users find the API inconsistent or unintuitive, requiring more effort to learn and use effectively.

  • Migrating from AngularJS to React
    Additionally, I wrote Jest and Enzyme unit tests to demonstrate how to go about unit testing the components, as test driven development (TDD) is another methodology my organization subscribes to. Jest is a unit testing framework that actually shipped with React if you use the Create React App CLI to make a new React project. And at the time, Enzyme was created by Airbnb and added additional functionality to Jest... - Source: dev.to / 28 days ago
  • How To Convert HTML CSS JS To React JS
    After converting your components, take some time to test your application. Make sure everything is working as expected. React’s development server automatically reloads your application whenever you save changes, which makes testing a lot easier. Tools like Jest and React Testing Library are also available to help you write tests for your components. - Source: dev.to / about 1 month ago

  • Top React Testing Libraries in 2025
    Enzyme is a widely-used testing utility that provides robust tools for interacting with and inspecting React components. Its API supports shallow, full, and static rendering, enabling developers to test components in isolation or with their child components. Enzyme also allows testing lifecycle methods, making it ideal for applications with complex state and props interactions. - Source: dev.to / about 1 month ago
  • How we have managed to run Enzyme tests with React 18 app.
    Like many other companies with mature software, we found ourselves at a crossroads with our React application. The app, initially developed in early 2019, was built with React 16 and used Enzyme for unit testing. Over the past five years, the app grew, evolved, gained new features, and went though minor and major refactorings. Obviously, as responsible engineers we always maintained unit test coverage around... - Source: dev.to / 6 months ago
  • What would you consider to be a must for a modern 2022 dev stack?
    React testing library instead of enzyme for testing react UIs. I'll never go back. Source: almost 3 years ago
