3 integration tests in Scala folder are failing with non default HTTP clients.

If we are changing httpClient in the TrelloTestFactory to AsyncTrelloHttpClient, AsyncTrelloHttpClient2 or RestTemplateHttpClient 3 integration tests are failing with following output.

./gradlew clean build

223 tests completed, 3 failed

As a solution for this kind of problems I could try to implement parametrized tests and integrate Travis for project.

using all clients in the new Scala-based integration tests sounds like a good idea.
the old Java-based tests follow this approach.
