UReport—Automation Reporting Web Application with Auto Failure Analysis

UReport is an Angular-based open-source web application that provides automation executions trends analysis and auto failure analysis based on historical data and failures. It is user-friendly for both the management teams and automation developers.

With public and easy-to-integrate RESTful API, UReport works for all automation testing frameworks. With the build-in dashboards, managers can see the past automation executions in various charts and have a crystal clear overview of the product's quality, trends for the stability of the automation results, and regression rate with past releases. Automation developers can focus on the root cause of individual test case failure with the failure messages, stack trace, and screenshots from any selected executions and compare current executions with the past ones.

Automation Testing Framework for UKG

A Java-based automation framework for UI and API automation using Selenium and REST Assured. It helped the company develop and maintain over 2,000 UI automation tests and 10,000 API automation tests over three years.

I acted as the designer and architect of the framework's UI part and a designer and contributor on the API part of the framework. The framework offered a customized page factory solution that reduced 30% line of code for UI page objects. The framework is also connected to an open-source reporting system I developed that helps the team troubleshoot daily failures and keep up the rapid development cycle while maintaining a 97%~99% automation nightly pass rate.

All-in-one JavaScript-based Framework for Touchtunes

A JavaScript-based automation framework works with web automation using Selenium, mobile automation using Appium, and RESTful API automation and command-line interface tests with socket.IO. I centralized all front-end-related automation within the same codebase and best practices, reducing maintenance costs with this framework.

QA Engineer Work in Cypress

The project is a crypto web responsive application. I was the sole QA automation engineer in charge of creating and scripting automation tests, running regression, and validating bugs in an agile process. We have 100% automation coverage on the front end that guarantees a stress and regression-free release.
