DetectorAssert usability problem for multiple matchers about test-driven-detectors4findbugs

[Grundlefleck]

Ack :)

IIRC writing matchers like that can be difficult in subtle ways*. I think we can get close to what you propose, but if not, do you think it would be helpful enough to print all reported bugs on a count mismatch? I'm assuming there will never be more than a handful emitted by a single detector.

• a colleague wrote some generic "collection contains" matchers, when you get into unordered collections, and trying to coordinate mismatch description to the closest thing matching, it gets tricky. May be able to reuse that though :)
