Start with one task your team actually does
Suppose someone pastes a support ticket into an AI assistant to draft a reply. The ticket might contain a customer email, an account number or an internal note. A useful deployment test starts with that task, using a fictional ticket and a unique test phrase. Keep real customer records out of the test.
Write down the browser, extension version, AI website and policy action before you begin. Test the route people use: typing, pasting and attaching a document are separate cases. A result from one route does not tell you what happens on the others.
Look at what was sent
For a Block rule, try to submit the fictional ticket and check whether its test phrase appears in an outgoing submission. An on-screen notice is useful feedback, but it is not enough on its own. Have the person running the technical test inspect the relevant request or a controlled receiver.
For Redact, confirm that a request was sent, that the replacement text is present, and that the original test phrase is absent. Then send an ordinary ticket without the phrase. It should still work. This last check catches a control that appears effective simply because it stops everything.
Keep a result someone else can repeat
Keep the test input, policy, installed version and observed result together. Add the matching dashboard event, if one was received. If the dashboard reports a block but the original text reached the receiver, record that as a failure.
Repeat the test after a browser restart and when the relevant integration changes. Record anything you could not test as unverified. This gives the administrator a specific answer—this version blocked this submission under these conditions—and a practical starting point for the next check.
