So, how do we test the inflation hypothesis?

We use a signal that interacts less that light, as such a signal may be able to travel through the dense plasma and reach us all the way from the big bang.

Gravity is the weakest force in nature and Einstein tells us that masses disturb space in a way that changes with time and subsequently produce gravitational waves, that is to say ripples in space-time.

So, just as shaking an electron produces an electromagnetic wave, when you shake your hands around you produce gravitational waves.

These waves disturb space-time in such a way that upon moving through a region of space they would cause space to appear to expand and contract inversely along differing axes.

The universe is full of gravitational waves, however they are very difficult to detect as gravity is so weak.
