forAll expectation against a fixed input set. #54

Closed LeifW closed 5 days ago

LeifW commented 6 days ago

One of the things ScalaTest has is "Table-driven property checks" - like ScalaCheck, but instead of a generator, it's just a fixed list of things to try. Or just a forAll to run an assertion against every element in a collection.

Basically, I want to run an assertion against e.g. every row of this CSV file of cities and their lat/longs, if if a row fails, get back an error message to the effect of "assertion failed for Seattle", and not the entire dataset. Does Weaver do that?

Sort of. The Expectations construct in weaver is monoidal, so you can do something like : 

import cats.syntax.all._

myList.foldMap(x => expect(...))

Closing the issue because it's not an issue. Please use github discussions instead if you have general questions related to the library.
