Configure spring cloud contract and Zuul proxy in the same project -
i have problem integrating spring-cloud-contract service on consumer side. in service use feign (to call other services) , zuul (for routing) spring-cloud. problem happens when try run test annotated @autoconfigurestubrunner. simple class:
@runwith(springrunner.class) @springboottest @autoconfigurestubrunner(ids = {"group:artifact:+:stubs:8080"}, workoffline = true) public class withcontracttests { @test public void test() {} } in output can see stubs started properly:
o.s.c.c.stubrunner.stubrunnerexecutor : stubs running runningstubs [namesandports={group:artifact:1.0.0-snapshot:stubs=8080}] and have error while creating spring context:

oh boy mistake. can file issue in contract? until have override existing class woth sth doesn't add servers list returned delegate creates new list servers added. haven't tested against zuul :/
it's been fixed (hopefully) here - https://github.com/spring-cloud/spring-cloud-contract/issues/82
