I don’t think there are testable hypotheses in history, though there are certainly falsifiable ones in the sense that they could be shown wrong (which does NOT mean they could be proven right).
A simple example is the hypothesis that Columbus was the first European to discover the New World. It was successfully falsified by finding a Viking settlement in Newfoundland.
However if you say that, for example, the main cause of WW1 was the Great Power rivalry, well, I don’t know how that could (realistically) be falsified.
