Tests for the `fact.extractione.singlePulse`

#205 and #202 show that we have missing coverage on the SinglePulse stuff

Is this about tests which invoke the streams processor? So far I only created only tests of the parts used inside the streams processor.

I'm not talking about the photonstream :) But about the old stuff.

Please don't call it "the old stuff" its not completely outdated, it has a different purpose

old != outdated
