GraphQL REST API Automation Tests

With the rise in popularity of GraphQL, I was the chosen person to make sure the testing could support this new technology. This required a lot of research and communication with developers and automation leads. In the end, I created a framework suitable for easy test addition and continuous integration with the purpose of writing tests for GraphQL API endpoints.

Front-end Automation Tests for a Company Search

I was solely in charge of test case planning, prioritization, and creation. In total, I automated over 300 front-end test for company search and search results. I was also monitoring and investigating the cause of failures of these tests, catching several critical bugs before the release to production.

The tests were written in Python; using pytest and Selenium WebDriver which ran on Jenkins.

Unit Tests Using Mockito

I wrote a unit test using the Mockito framework as the coverage was falling behind due to fast feature development. We tracked the coverage increase with JaCoCo.
