TestAnnotations interface

Added in v2.0.0 Source

The Annotations trait provides access to an annotation map that tests can add arbitrary annotations to. Each annotation consists of a string identifier, an initial value, and a function for combining two values. Annotations form monoids and you can think of Annotations as a more structured logging service or as a super polymorphic version of the writer monad effect.
