Sep 2020 - Jan 2023
Java version of the Playwright testing and automation library
Role in this project:
QA Engineer / Test Automation Engineer
QA Engineer / Test Automation EngineerContributions:44 releases, 341 reviews, 695 commits in 2 years 4 months
Contributions summary:Yury's commits focus on implementing and improving test automation for the Playwright Java library. The contributions involve adding support for new features, specifically the `waitUntil` option in the `frame.navigate` method, as well as refactoring and adapting existing tests. These changes demonstrate a strong understanding of the library's API and the process of creating robust tests, which suggests a QA or Test Automation Engineer role. A shift from `with` to `set` prefix on some of the Java API makes it also likely that the user is trying to keep the Java API in sync with upstream.
