Feature request: partial body matcher

[ryantm]

It would be nice if there were a way to match part of the body of a response. Sometimes responses contain random bits that you don't care about testing.

You can write your own custom matchers to do whatever you like using ResponseMatcher. For instance:

partialMatcher :: String -> ResponseMatcher
partialMatcher expected = ResponseMatcher {
    matchStatus=200
  , matchHeaders=[]
  , matchBody=MatchBody (\_ actual -> do 
      if encode expected `isInfixOf` actual
        then Nothing
        else Just "expected string wasn't a partial match of actual!"
    )
  }

You can then use this in your tests like so:

let expected = "expected partial response"
request methodPost someTestPath [] body `shouldRespondWith` partialMatcher expected
