CODING THAT SPARKS JOY WITH QUARKUS


Does your heart beat faster when you’re developing your Java application? Do you Spark Joy when you’re coding it? If not, then it’s time to leave some old ways behind.


Join us on this live coding session and become Ahead of Time with Quarkus. You’ll learn to love how your old and new favorite APIs will start in a matter of milliseconds, and consume tiny amounts of memory. With hot reload capabilities for development that will give you instant Sparks of Joy! Life is too short to wait for your big, fat, slow, and memory hog app to re(start).

CONSUMER DRIVEN CONTRACTS: THE MISSING LINK IN SERVICE TESTING


You’ve built your 12 Factor Microservices application and all tests pass with 95% coverage. Looking good, right?Then you deploy to production, and kapow! Rollback! What happened?


Well, your tests all passed but you never tested the endpoints. Consumer Driven Contracts is a development model for specifying contracts that are shared by providers and consumers, to generate boundary tests in the form of executable stubs. In this talk, we will build a client and server application where all the tests pass. Then we will show how they fail when deployed. Finally, we will see how Spring Contracts could have saved a lot of heartache. Here’s a list of useful topics we’ll cover:


Spring Contracts, and some of its underlying technologies, including:



  • Project organization; POM dependencies

  • Contract syntax

  • Generating stubs from contracts

  • Running the stubs on the consumer side

  • Verifying the stubs on the producer side

  • Versioning

  • A brief look at the underlying testing frameworks:

  • MockMvc

  • WireMock API testing framework

  • RestAssured testing framework

  • Mockito

  • Verifying non-Java APIs
