Testing Select Components with React Testing Library
<p>Testing Select components in React can be challenging due to factors such as simulating user interactions, handling asynchronous behavior, variability in implementation, the complexity of nested components, and accessibility concerns. <a href="https://testing-library.com/docs/react-testing-library/intro" rel="noopener ugc nofollow" target="_blank">React Testing Library</a> simplifies this process, but it doesn’t eliminate all the challenges.</p>
<p>In this post, we’ll explore some of the best practices for testing Select components with React Testing Library. We’ll begin by writing tests for a wrapper on top of a native HTML <code>select</code>, and then proceed to test the components using Select components from the popular <a href="https://react-select.com/" rel="noopener ugc nofollow" target="_blank">react-select</a> library. The final code is available on <a href="https://github.com/Clarity-89/test-select" rel="noopener ugc nofollow" target="_blank">GitHub</a>.</p>
<h1>Setting up</h1>
<p>Before writing tests, we’ll create a sample React app and install the <code>react-select</code> package.</p>
<pre>
npx create-react-app test-select
npm i react-select</pre>
<h1>Testing native HTML select</h1>
<p>We’ll begin by testing a component that acts as a wrapper for the native HTML <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select" rel="noopener ugc nofollow" target="_blank">select</a> element. Having such a component is quite common, as it abstracts the logic of rendering options.</p>
<p>We’ll place all the code inside the <strong>components</strong> folder. We start by creating a <strong>Select.js</strong> file there with our first component.</p>
