Installation

Install in three clicks.

1. Open the Chrome Web Store listing

Go to:

https://chromewebstore.google.com/detail/testkase-accessibility-to/pcnkpjhbkjedhhfdploloipmpnbihfep

The toolkit is free. No credit card, no setup.

2. Click "Add to Chrome"

Chrome will prompt you to confirm the permissions. The extension requests:

• activeTab — to scan the tab you're on.
• storage — to remember your session and captured results.
• scripting — to add the checking engine to the page you are testing.
• tabs — to notice when you move to a new page, so it can add that page to the same report.
• debugger — used to read and check the page during a scan.

Chrome also asks to let the toolkit read and change data on all websites. It needs this so it can check any website you open. It also talks to TestKase so your saved reports reach your workspace. It runs no code from the internet — the checking engine is built into the extension.

3. Pin the toolkit

After install, click the Chrome Extensions puzzle icon in the toolbar, find TestKase Accessibility Toolkit, and click the pin icon. This keeps the toolkit one click away.

4. Sign in

Open the website you want to test and open DevTools (F12 or ⌥⌘I). Click the Testkase Accessibility Toolkit tab.

• Don't see the tab? Click » at the top of DevTools to see more tabs.
• Was DevTools already open when you installed? Close DevTools and open it again.

Not sure what to do? Click the toolkit's icon in the Chrome toolbar. It shows these same steps.

If you already have a TestKase session in the browser, the toolkit signs you in automatically. It does that by briefly opening a hidden background tab on testkase.com to pick up your existing session, then closing it — so you may see a tab flicker open on first use, and the automatic sign-in cannot work in a private/incognito window or in a different browser profile from the one you signed in on.

If no session is found, the tab closes quietly and nothing happens: click Sign in to complete a one-time login. Sessions refresh automatically so you stay signed in across browser restarts.

Where it works

The toolkit works on any website, including sites that need you to sign in.

It does not work on Chrome's own pages (addresses that start with chrome://) or on the Chrome Web Store. Chrome does not let any extension run there. If you click the toolkit's icon on one of these pages, it shows a red warning. Open the website you want to test first.

Browser support

Works on any Chromium-based browser with DevTools extension support:

• Google Chrome
• Microsoft Edge
