EXPERIENCE
CONCENTRIX Feb 2024 – Current
Client: Union Pacific Rail Road, Omaha, USA
PTC Test Analyst
Description: Positive Train Control systems are integrated command, control, communications, and information systems designed to prevent train accidents by controlling train movements with safety, security, precision, and efficiency. PTC uses communication-based/processor-based train control technology. PTC is designed to prevent Train-to-train collisions, Derailments caused by excessive train speed, Train movements through misaligned track switches and Accidents to Railroad workers by incursion into established work zones.
Responsibilities:
Perform Integration, Functional, Regression and End to End testing to verify PTC products like Onboard, Back Office Server and Dispatch systems meet functional requirements.
Analyzing the requirements mentioned in the Business requirement docs, preparation of QA documents such as Test Scenarios, Test Cases, and defect reports.
Perform requirements tracing to Test Specifications/Procedures and Test cases to prove enough coverage of system and subsystem requirements. Review Test cases, Test plans.
Configure and Installation of onboard software in Train Management Computers in lab environment.
Prepare detailed test cases, test plans, test scenarios by understanding the business logic and user requirements.
Developing and executing Automation test scripts for segment testing, Lab Integration Nearest Neighbor testing & Lab Integration End to End testing using Python Automation framework to perform validations on Onboard (I-ETMS), UPBOS & CAD-X systems.
Following QA process for Systems Engineering Process Group that is leading client department's CMMI Level 3 certification.
Co-ordinate with offshore/onshore team members and provide technical guidance for team members. Actively facilitating the coordination and completion of the scheduled tasks with team members.
Generate Test Summary Reports, log defects in ALM/ Quality Center. Involve in defect triage meetings.
Performed manual testing, reported defects using Sales force and JIRA, ensuring timely resolution and re-testing of fixed issues.
Involved in end to end testing, installation, configuration and testing of complex systems in both Field and Lab environments.
Designed and implemented custom-built test automation frameworks using Python, focusing on creating robust, reusable, and scalable solutions for automating desktop application testing in a three-tier architecture.
Developed and executed automation scripts using Python libraries such as PyAutoGUI for UI interactions (e.g., mouse movements, clicks, keyboard inputs) and Pytesseract for OCR-based text extraction from images, ensuring comprehensive test coverage for visual and text-based components and Win32gui
Integrated automated tests into the CI/CD pipeline to ensure continuous validation of application functionality, working closely with DevOps teams to improve test execution speed and feedback loops.
Managed project source code and collaborated effectively using GIT for version control, ensuring smooth code management and a streamlined process for code integration and deployment.
Read and analyzed data from Tableau reports, creating visual representations of test results and metrics to help make informed decisions and identify trends in test execution, quality and overall project performance.
Developing and executing Automation test scripts for segment testing, Lab Integration Nearest Neighbor testing & Lab Integration End to End testing using Python Automation framework to perform validations on Onboard (I-ETMS), UPBOS & CAD-X systems.
