testaaja A canopy over a bed.
1603, (w), translating Michel de Montaigne, Essays, III.13:

And I could as hardly spare my gloves as my shirt, or forbeare washing of my hands both in the mornng and rising from the table, or lye in a bed without a testerne and curtaines about it, as of most necessary things.

No testers to the bed, and the saddles and portmanteaus heaped on me to keep off the cold.

With our shaggy jackets drawn about our shoulders, we now passed the Tomahawk from one to the other, till slowly there grew over us a blue hanging tester of smoke, illuminated by the flame of the new-lit lamp.
