A few months ago, I was running QA on a fintech platform a customer-facing portal where businesses fund a wallet and spend from it. Every wallet feature passed testing. Deposits credited correctly. Transactions deducted correctly. The ledger balanced to the kobo.
There was just one problem: nowhere in the portal could a user see their wallet balance.
Not on the dashboard. Not on the wallet page. Not anywhere. Users could add money and spend money, but the single number they cared about most how much do I have left? didn't exist in the UI.
Every backend test passed.
Every API returned correct data. Every ticket was closed. By our own definition of done, the wallet was finished.
