The best testing strategies for frontends
Probably Enzyme was the first to popularize component testing in React by doing shallow rendering and expecting some things to be there in the React component tree. Then React Testing library came and took component testing to a whole new level.

What is integration testing in UI/Front End?
Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.

Testing Intercepting Routes
I'm writing an intergration test with Testing Library where I'm on a boards dashboard area and a user can click a button to create an item on the board. I'm using an intercepting route to do show the popup form. Once finished the user goes back to their area and should see the created board.

How to run visual tests in 2023
There are great tools like Testing Library that render a single component in a single state and then programmatically inspect the resulting DOM. However, the salient details of the rendered HTML – like color, layout, and scale – are hard to express. So, the tests end up brittle (over-specified) or insufficient (under-specified).

Let's Make Learning Frontend Great Again!
LiveCodes provides many of the commonly used developer tools. These include Monaco editor (that powers VS Code), Prettier, Emmet, Vim/Emacs modes, Babel, TypeScript, SCSS, Less, PostCSS, Jest and Testing Library, among others. All these tools run seamlessly in the browser without any installations or configurations. It feels like a very light-weight version of your own local development environment including the keyboard shortcuts, IntelliSense and code navigation features.

How to Write Accessible Technical Documentation – Best Practices with Examples
Videos To caption videos, HTML is a great option. But if you are using markdown, you can embed videos from YouTube and Vimeo using the tag. These apps offer in-built caption support so you can enable captions before adding the embed code.
You could also install third-party plugins for this purpose.
Here’s another tip: avoid flashing content in your videos as it could lead to seizure triggers. If your video has flashing bright colours, ensure that it does not exceed two times within a second.
Add transcripts to audios and videos
It’s a good idea to add transcripts to your audio and video content. Not everyone will want to watch or listen to the content. But they may be curious to know what it is about.
By adding a transcript, you make it easier for anyone to navigate through the content and get the information that they need.
Transcript for audio
For audio content, you can insert transcripts using HTML.Here’s an example:
controls muted> src="ringtone.mp3" type="audio/mpeg">
Here is a transcription of the text
00:03 = I am going to be productive today
00:05 = I am going to be productive today
00:08 = I am going to be productive today
00:10 = I need to be productive today
00:11 = I have to be productive today
00:13 = I should be productive today
00:16 = I am going to be productive today
00:18 = I ought to be productive today
00:21 = I have to be productive today
00:23 = Productivity matters to me
Enter fullscreen mode Exit fullscreen modeFor markdown documentation sites like Docusaurus, you can create a custom component.
In your
src/components
folder, create a file namedtranscript.jsx
.Insert this code:
import React, { useState } from 'react'; export default function Transcript({ }) { const [showTranscript, setShowTranscript] = useState(false); const toggleTranscript = () => { setShowTranscript(!showTranscript); }; return ( <div> <a href="#" onClick={toggleTranscript}> { showTranscript ? 'Hide transcript' : 'View transcript' } </a> {showTranscript && (
(insert your transcript text here) div> )} </div> ); }
Enter fullscreen mode Exit fullscreen mode- Go to your markdown file and import it.
import Transcript from '@site/src/components/transcript';
Enter fullscreen mode Exit fullscreen modeNote: I added some tweaks to the code to make transcript display optional. You can edit it if you want the transcript to show as the page loads.
Transcript for video
Now for videos, YouTube is a great option. It provides inbuilt transcripts for your videos. So, you can always embed YouTube videos in your docs.The transcript is in the video description after the main details. The transcript will display with the timestamps when you click the “Show Transcript” button.
Add code snippets and use the colour contrast technique
How to add code snippets
Use code blocks within the text to explain code instead of images. You could also use code snippets to showcase the output of your code. Unless it is necessary to add an image, you should use code snippets.For instance,
index.html
A calculator app
Enter fullscreen mode Exit fullscreen modeThis will allow screen readers to read through the code, which they are not able to do with screenshots.
Colour contrast technique
The colour contrast technique implies using colours that are opposite or heavily contrasting.For example, using black text on a white background has a high contrast, as opposed to using light brown text on a brown background.
When combining colours, you could use an accessible colour palette like Color Safe.
Add translation options
There are documentation sites that provide translation options where you can build your docs in multiple languages, websites like Jekyll. This is an example.
Docusaurus is also another doc site that provides multilingual options using Crowdin or Git.
Follow through this guide to set up translation and localization on Docusaurus using Git.
Follow through this guide to set up translation and localization on Docusaurus using Crowdin.
Use accessibility testing tools
There are tools you can use to check for errors in accessibility in your docs. Some examples are WAVE (Web Accessibility Evaluation Tool) and AXE (Accessibility Engine).
Also, you can get the NVDA(NonVisual Desktop Access) screen reader to test out your content. This software will let you know how the content of your documentation will be perceived by a user using a screen reader.
Set up an improvement or suggestion box
Finally, it may not be possible to cover the needs of every user. So you could add a suggestion or improvement box, allowing users to send feedback about how you could further improve the content. Hearing firsthand from users can help you know how best to make the docs accessible for them.
To add an improvement box, you could use an external form link that stores the users’ inputs or you could set up the suggestion box in the docs.
How to add an external form link in Docusaurus
You would need to create a custom component for that.
Go to
src/components
folder and create a filefeedback.jsx
.Add this code:
import React from 'react'; export default function FeedbackButton({ href }) { return ( <a href={href} target="_blank" rel="noopener noreferrer" > Give Feedback </a> ); };
Enter fullscreen mode Exit fullscreen mode- In your markdown file import it:
import FeedbackButton from '@site/src/components/feedbackbutton';
Enter fullscreen mode Exit fullscreen mode- Insert the link
Enter fullscreen mode Exit fullscreen modeWhen you run it on your docs, it should showcase a link to Google forms. Google Forms is an example, you could add the link to your company website or server.
Here’s what it’ll look like:
Summary
To follow and implement these accessibility best practices, you can consider creating or using an already made style guide. This can help you consistently implement these practices and make it easier for you and other technical writers on your team.
There are style guides focused on accessibility for technical writers, such as the following:
Accessibility style guide by Heyawhite
Write accessible documentation by Google for developers
Writing for Accessibility by MailChimp content style guide
That sums up my tips about web accessibility practices in writing. I’m a technical writer, and you can reach out to me on Instagram or hire me via Upwork. Thank you for reading.
