Experience

Python Web Selenium End-to-end Tests Project

https://github.com/Haisenberh/Python-Selenium-Web-Test-Portfolio-Project

This is a Python-based automation portfolio project that is developed to test the Web UI part using the Pytest-BDD framework with the latest Selenium web driver. The page object and singleton design patterns are used to minimize test code and maximize the flexibility of usage. Tests can be run as a continuous integration tool in a Docker container or locally using CircleCI. After tests are executed, the beautiful report is generated using the Pytest-HTML framework.

Python API Tests Project

https://github.com/Haisenberh/Portfolio-Python-API-Testing-Project

This is a Python-based test automation project that is developed to test the REST API back end using the Pytest framework. Also, this project is running as a continuous integration tool using CircleCI. After tests are executed, the beautiful report is generated using the Pytest-HTML framework.

Global Health and Wellness Platform
