  • This is Dr. Wakina’s season, the season he restores joy, peace and prosperity to broken relationships/marriages. He is the one and only spiritual healing doctor that has the power to do unimaginable things with his email:- [email protected] With big faith and trust I have on Doctor I got results 7days after some inspirational spell cast that brought my husband back and made him realize his mistake for leaving us because of misunderstanding we usually had because of his affairs with his concubine. He realized after the spell that no woman is prettier than me or any woman that can love, care and satisfy him like I do. He realized he has a beautiful and promising family. I was not afraid contacting Dr. Wakina because I know he is one of the genuine spell doctors that can bring back my better half without negative effects. I am exited you read this wonderful testimony from a happy wife and mother. I pray and wish unending joy, peace and prosperity in your relationship/marriage… cheers!

  4. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Introduction • Producer – service that exposes an API • Consumer – service that consumes the API of the producer • Contract – agreement between producer and consumer how the API will look like • Consumer Driven Contracts – approach where the consumer drives the changes of the API of the producer

Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ What are we going to code? • Consumer – service that gets beer requests – has to ask another service if the client can get the beer • Producer – service that checks if the client is old enough to buy beer • Feature – if the user is too young - the beer will not be sold – otherwise the beer will be granted

  7. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Summary With Spring Cloud Contract and Consumer Driven Contracts: • we’ve created an API that suits the consumer and the producer • expectations were defined by readable contracts that were tested against the producer • producer stubs can be reused by consumers • starting and setting stubs is fully automated
  8. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Summary - Consumer flow 1 Consumer • starts TDD - writes the test for the feature • clones producer code to change the API locally • in the cloned producer code converts contracts into stubs and installs them locally • in the consumer code turns Stub Runner to offline mode • configures Stub Runner to download stubs of the producer • red - green - refactor on the API and tests • repeats the process until the tests are green and API acceptable • files a PR to the producer with the contract proposal
  9. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Summary - Producer flow Producer • takes over the PR • writes the missing implementation that will make the autogenerated tests pass • merges PR and deploys the JARs with the app and the stubs
  10. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Summary - Consumer flow 2 Consumer • switches off the Stub Runner’s offline mode once the producer uploads the stubs • configure Stub Runner by providing the URL to a repo with stubs • will have its test broken if the producer makes any breaking changes of the API
  11. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Why use Spring Cloud Contract Verifier? • Possibility to do CDC with messaging • Clear and easy to use, statically typed DSL • Automatic generation of tests from the defined Contract • Stub Runner functionality - the stubs are automatically downloaded at runtime from Nexus / Artifactory • Spring Cloud integration - no discovery service is needed for integration tests
