Micronaut Testing with JWT Authentication multiple Service

Question

I have multiples Services: ServiceA, ServiceB, ServiceC with JWT Authentication and Propagation enabled. The service responsible to authenticate the users is ServiceA.

So how can I testing (JUnit5) my services B and C if authentication is enabled and this services don't know how to authenticate?

In gitter.im/micronautfw there is an answer using MockAuthenticationProvider implements AuthenticationProvider and SecurityBypassFilter implements HttpClientFilter to Mock the authentication logic.

    package demo

    import io.micronaut.context.annotation.Requires
    import io.micronaut.context.env.Environment
    import io.micronaut.security.authentication.AuthenticationFailed
    import io.micronaut.security.authentication.AuthenticationProvider
    import io.micronaut.security.authentication.AuthenticationRequest
    import io.micronaut.security.authentication.AuthenticationResponse
    import io.micronaut.security.authentication.UserDetails
    import io.reactivex.Flowable
    import org.reactivestreams.Publisher

    import javax.inject.Singleton

    @Requires(env = Environment.TEST)
    @Requires(property = 'spec.name', notEquals = 'SecuritySpec')
    @Singleton
    class MockAuthenticationProvider implements AuthenticationProvider {

        @Override
        Publisher<AuthenticationResponse> authenticate(AuthenticationRequest authenticationRequest) {
            if ( authenticationRequest.identity == 'user' && authenticationRequest.secret == 'password' ) {
                return Flowable.just(new UserDetails('user', []))
            }
            return Flowable.just(new AuthenticationFailed())
        }
    }

and

    package groovycalamari.bookmark

    import io.micronaut.context.annotation.Requires
    import io.micronaut.context.env.Environment
    import io.micronaut.http.HttpResponse
    import io.micronaut.http.MutableHttpRequest
    import io.micronaut.http.annotation.Filter
    import io.micronaut.http.filter.ClientFilterChain
    import io.micronaut.http.filter.HttpClientFilter
    import org.reactivestreams.Publisher

    @Filter('/**')
    @Requires(env = Environment.TEST)
    @Requires(property = 'spec.name', notEquals = 'SecuritySpec')
    class SecurityBypassFilter implements HttpClientFilter {

        @Override
        Publisher<? extends HttpResponse<?>> doFilter(MutableHttpRequest<?> request, ClientFilterChain chain) {
            request.basicAuth('user', 'password')
            return chain.proceed(request)
        }
    }
