What makes a hypothesis a testable?

Answer 1

It must be proven from right to wrong

Answer 2

A hypothesis is testable when we can determine experientially whether it is likely to be false or more likely to be true. That means we must be able to distinguish between it being true or false observationally. Thus, equally important to finding observations that confirm the hypothesis, we must be able to specify what it is we expect to see in the case that the hypothesis is false: the hypothesis must be falsifiable in order to be testable.

It must be able to be proved right or wrong.
