Exam: Acceptance Test–Driven Development based on Concordion
Illustration from "Growing Object-Oriented Software, Guided by Tests"
Exam is oriented on declarative end-to-end black\graybox application testing in a way a manual tester would do it: send request, verify response\database\message queue etc.
- Declarative glue-code free approach
- Attractive, flexible documentation thanks to Concordion
- Widly used set of testing tools under the hood: dbunit, rest-assured, xml-unit, json-unit
// Typical microservices setup (Web API + DB + MQ) testing:

//same as:

// UI testing
