Hi How to change this custom matcher (https://github.com/kitsemets/wiremock-custom-matcher-test/blob/main/src/test/java/com/github/kitsemets/wiremock/matcher/CustomJsonMatcher.java) so that it would print out the diff message given by AssertJ? It uses the recently added

DiffDescription

class (https://github.com/wiremock/wiremock/pull/2771), but I can't figure out a way to use it correctly with my custom matcher which uses AssertJ to diff the json object in the POST request body. Two test methods attempting to show my goal: https://github.com/kitsemets/wiremock-custom-matcher-test/blob/main/src/test/java/com/github/kitsemets/wiremock/matcher/CustomMatcherTest.java

thanks for creating a minimal project show casing your query very clearly. the reason that you're not seeing the expected diff message is because the

DiffDescription

class is only used when rendering near miss responses, not when performing verifications. for verifications,

JUnitStyleDiffRenderer

is used, which is a more simplified renderer that does not take into account the

DiffDescription

thank you for the response.
