Quarkus, Gradle, WireMock. Dev Services for Gradle projects

Quarkus has many local development capabilities, including the recently released Dev Services that usually run with Testcontainers under the hood. We can leverage Dev Services to provide real-time API provider development experiences for Quarkus-based services and client apps.

In this session, I provide an overview of using Quarkus and its Dev Services in Gradle projects. We take WireMock as an example. I will show how to develop a REST API and gRPC 3-tier client-service-database app with the help of Quarkus, Gradle, and WireMock. DM for the Testcontainers edition!.

21. Ways to do API integration testing 1. Testing against Production/Staging servers 2. Testing against a simplified/containerized instance (e.g. Testcontainers) 3. Modeling (aka Mocking) at the API provider level (e.g. WireMock or Microcks) 4. Mocking at the code level 21 Slow Fast Nope Accu- rate * For Testcontainers, see the slides
22. 22 wiremock.org/docs/stubbing IF (request_url) THEN (response) * * it gets MUCH more complex WireMock Config JSON: Client library response request Client App Mock API Server HTTP/2 API Mocking 101

41. + 41 • WiP: Develocity Pilot in Quarkus • For many open source projects: Gradle sponsors Develocity licenses/hosting, helps with build optimization and developer productivity • Maven, Bazel and sbt projects welcome gradle/develocity-oss-projects
42. What I’m looking forward to? • Feedback on Gradle Plugin for Quarkus • Promoting WireMock and Microcks Dev Services as official ones • Quarkus, Gradle and Develocity developer experiences • Any other feedback on Gradle :) 42
