This looks pretty cool! One thing I wonder, though, why am I seeing all
these \n values rather than actual newlines in the "actual" value, which
would make the output so much easier to read? Is there any way to configure
or use it differently that would avoid this issue? (This is with lein test
right after adding the dependency to my project.clj and changing one test
to use matcha). Also, the "expected" message looks a little broken, should
it not instead say something like expected: "a map with entry :status that
equals 201"? (there is no word between "that" and "201"):
FAIL in (starting-and-stopping-production-server-works-as-expected)
(httpkit_test.clj:17)
start-production-server causes HttpKit and Hazelcast to start
expected: "a map with entry :status that 201"
actual: "a map with 200\n <class java.lang.Integer>\n diff:\n +:
201\n\n -: 200\n at key :status (was {:orig-content-encoding nil,
:trace-redirects [\"http://localhost:12081/idp/status\";], :request-time
