Indeed, looking at things along those lines, James, 'testable' would
seem to put the bar too low. I'd raise it to 'tested' :-).

The usual word is 'falsifiable'.
That is, you can devise an experiment to test it.
Preferably lots of them.

To be
sure, this would imply that a hypothesis is not in that sense of the
word scientific, a scientific statement.

A hypothesis is an untested scientific statement.
For some level of tested.
