Video: Accessibility Granted: Building Inclusive Components One Test at a Time

From Author:

Creating accessible React components is essential yet challenging, especially when retrofitting existing codebases. This talk will explore how Test-Driven Development (TDD) can streamline the process, reduce development costs, and ensure high accessibility standards from the start. Attendees will learn practical strategies for integrating accessibility into their development workflow and discover tools to test UI components directly in the IDE.

This talk has been presented at React Summit US 2024, check out the latest edition of this React Conference.

At Evinced, the mission is to make the web more accessible for everyone. Accessibility issues are common despite intentions. Today's Talk focuses on coding in an accessible way using TDD to catch defects early. Unit tests can be written to ensure accessibility requirements are met. Testing Library provides utilities for testing accessibility. The ATDD approach allows continuous creation of tests for compliance. Unit testing is valuable for complex components. Advanced has developed an SDK called the Unit Tester for automating accessibility tests.

FAQ

Evinced's mission is to make the web more accessible for everyone, ensuring that people with disabilities are not excluded from digital experiences.

Web accessibility is crucial because approximately one in six people worldwide live with significant disabilities. Ensuring accessibility allows these individuals to access digital content and services effectively.

Common accessibility issues on websites include elements that are only accessible by mouse, lack accessible names, and have missing required semantics, making them difficult for assistive technologies to interact with.

Evinced provides tools for developers, designers, and other professionals to detect and prevent accessibility violations early in the product development lifecycle.

ARIA (Accessible Rich Internet Applications) attributes enhance web accessibility by providing semantics that assistive technologies rely on to interpret content correctly.

A Toggle component, like a switch or toggle button, provides real-time feedback on binary choices or actions, and its accessibility involves having the correct semantics for assistive technologies.

Considering accessibility from the start helps prevent costly fixes later in development, ensures compliance with accessibility standards, and improves the overall user experience for all users.

The Unit Tester SDK automates accessibility test creation, ensuring components support screen reader and keyboard operation, providing instant feedback in the development environment.

Test-driven development (TDD) is an approach where tests are written before the code. It fosters better design, encourages simpler code, helps catch defects early, enhances code quality, and improves maintainability.

Unit testing can be used to ensure that components meet accessibility requirements by validating their operability with keyboard and screen readers, often using tools like JSDOM for testing.

Everyone Can Easily Write Tests
Playwright is a reliable end-to-end testing tool for modern web apps that provides one API, full isolation, fast execution, and supports multiple languages. It offers features like auto-weighting, retrying assertions, seamless testing of iframes and shadow DOM, test isolation, parallelism, and scalability. Playwright provides tools like VS Code extension, UiMode, and Trace Viewer for writing, debugging, and running tests. Effective tests prioritize user-facing attributes, use playwright locators and assertions, and avoid testing third-party dependencies. Playwright simplifies testing by generating tests, providing code generation and UI mode, and allows for easy running and debugging of tests. It helps in fixing failed tests and analyzing DOM changes, fixing locator mismatches, and scaling tests. Playwright is open source, free, and continuously growing.

React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn

Compared to unit testing, end-to-end testing aims to interact with your application just like a real user. And as we all know it can be pretty challenging. Especially when we talk about Mobile applications.
Tests rely on many conditions and are considered to be slow and flaky. On the other hand - end-to-end tests can give the greatest confidence that your app is working. And if done right - can become an amazing tool for boosting developer velocity.
Detox is a gray-box end-to-end testing framework for mobile apps. Developed by Wix to solve the problem of slowness and flakiness and used by React Native itself as its E2E testing tool.
Join me on this workshop to learn how to make your mobile end-to-end tests with Detox rock.
