Testkit module #33
Description
Hi! It would be nice to have a testing module that'd let you do something like Circe's codec laws.
I'm building something like this for work, I'll see if I can contribute it back here later.
Things I'd like to see in this kind of thing:
def codingTest[A: XmlEncoder: XmlDecoder](value: A, expectedEncoding: String): Unitdef roundtripTest[A: Arbitrary: XmlEncoder: XmlDecoder]: Assertion = forAll(...)
It would probably be better to compare the AST instead of strings, though. I suppose currently I can defer to aalto's parser. These would probably help (especially in test land):
- Must have: function that parses String to a XML AST with an Either in the result
- Nice to have: XML interpolator (doesn't need to support symbol interpolations in the beginning, just calling the parser at compile-time would be nice)
- Nice to have: type alias / newtype for the AST type, so that users don't need to find the right import from aalto
Update: I also just realised codingTest would need a way to check equality (in the "value encodes back as expectedEncoding" test) ignoring the missing fields...
