Functional testing

Developers naturally walk the route they designed and cannot see their own blind spots. A separate tester deliberately goes off-route: nonsense input, a lost connection, someone hammering the pay button twice.

As a rule of thumb, 25 to 35 per cent of development effort. With less, only core journeys are covered and some bugs slip through to users. That trade-off can be perfectly reasonable if it is a conscious one.

Gladly, and it is a frequent request: the software runs, but nobody fully trusts it. We explore it first and derive the cases from how it really behaves, because specifications are usually missing.

Smaller jobs are billed at DKK 895 per hour, excl. VAT. Recurring pre-release cycles can be agreed at a fixed price, so the budget is known up front.
