Sidenis Russia | Jan 2017 - Jan 2017

QA Automation Engineer

Project A Decision support system for a large reinsurance company Our team develops a large distributed web-application which includes both backend and frontend parts. The backend has microservices architecture and includes various RESTful-systems which communicate through both synchronous and asynchronous API. To simplify testing management process I've developped a configurable REST-client for JIRA&Zephyr. This client reduces manual effort during the testing by automating routine tasks. My responsibilities: - simple unit tests (using such technologies as Mockito, JUnit); - Integration tests with in-memory DBs, WireMock; - Spring MVC Test Framework; - reports for code coverage and other metrics; - Sonar Cube configuration; - Jacoco Maven Plugin configuration; - Zephyr plugin for JIRA; - Maven projects configuration; - CI/CD configuration; - code review.
