Most European cities have at least one place that will test you for free, without your name, and without asking why you came. They are not hidden and they are not only for people in this industry. They are simply not advertised, so most people never learn they exist.
Below is what the network knows about, city by city. Opening hours and walk-in rules change, so check before travelling.

How soon a test tells you anything
Every test has a window between exposure and the point at which it can detect anything, and testing inside that window tells you nothing useful. A negative result the morning after is not a negative result. Ask the clinic what window applies to the test they are giving you, and when to come back.
This is not medical advice
It is a list of places, compiled by a directory. Anything about your own health belongs to a clinician, and the people at every address above are exactly that.
