Feed your automation messy input on purpose

Before you trust an automation with real work, try to break it. Send it a blank field, a misspelled name, an image where it expects text, a form submitted twice in a row.

This matters because the inputs you plan for are never the only inputs you get. Customers paste extra spaces, skip fields they think are optional, and submit the same form because the button did not seem to respond. An automation that only gets tested with clean, tidy examples will look great in a demo and fall apart the first messy afternoon it meets real people. Testing with rough input on purpose shows you the weak spots while the stakes are still low. I make a habit of pasting a blank field or a doubled-up submission into any new automation before I trust it near a real customer.

Keep a short list of the odd cases you tried, so anyone maintaining the automation later knows what has already been checked.

Try this today: take your newest automation and try three deliberately messy inputs before you let real customers near it.
