Portfolio

Java and Selenide Test Automation Framework

Developed a custom test automation framework from scratch using Java, TestNG, Selenide, Allure Reports, Docker, Rest-assured, and full GitLab CI configuration.Framework features:• Modular design with Page Object Modal architecture• Extremely stable, maintainable, and readable• Easy to work with thanks to its design that implements near-English test step methods• Ability to measure load times• Ability to intercept and manipulate HTTP requests and responses• Ability to send API calls to set up software configuration and test data• Detailed Allure Test Reports with historical data• Full integration with GitLab• Docker and Docker compose set up

Protractor Test Automation Framework

I developed a test automation framework for a loyalty management application which is widely used in the travel industry. Framework Features:· Designed according to the POM (Page Object Model) and uses separate objects for actions and selectors separated from the main page objects.· Extensive reporting capabilities which included the ability to send regular emails to the relevant parties about the test execution status.· The ability to send/validate API calls (REST requests) for software and test data configuration.· The ability to check the load times of the page resources and create warnings about the delayed ones.

Java Test Automation Framework

I designed an adaptable and reusable test automation framework using Java and Selenium technologies. The software is used for testing a wide variety of web applications including factory maintenance management systems, inventory tracking and order management applications, and other web applications that are developed for commercial and enterprise usage. Framework Features: · It was designed according to POM (Page Object Model). · Implements page and element factory structures. · Possesses extensive reporting capabilities. · Validates database entries and file contents. · Has the ability to use external DOCX, DOC, XLS, XLSX, CSV, and JSON files for inputting test data.

Python and C++ Based Custom Test Automation Software

I participated in the development of a test automation software that is used in the defense industry by implementing a record-and-play functionality. The software is used for performing memory injections on industry-leading military simulators for testing purposes.This Python-based automation software was used in conjunction with a separate C++ based software in order to perform memory injections.

R&D Activities and Proof of Concepts

I participated in R&D activities by constantly exploring new technologies, exploring their capabilities, and assessing whether the adaptation of the new technology is feasible or not by designing proof-of-concept applications.
