-
Focused on critical workflows such as appointment scheduling, EMR access, and patient data entry, ensuring all functionalities performed seamlessly across environments.
-
-
E2E Testing:
-
Built a separate end-to-end testing suite for faster execution of critical user scenarios.
-
Rapidly executed real-time tests, covering functionalities like user authentication, booking processes, and telemedicine sessions.
-
Leveraged Cypress’s native parallel execution capabilities to shorten test cycles without compromising coverage.
-
-
API Automation Testing:
-
Developed a robust API testing suite to validate various endpoints that support patient data transfer, appointment handling, and insurance claims processing.
-
Automated tests covered functionalities like verifying API response codes, schema validation, data security, and error handling.
-
Focused on ensuring all APIs handled sensitive patient data in compliance with HIPAA, including encrypted data transfers and secure token-based authentication.
-
Validated integration between hospital systems, third-party services (insurance, payment), and the central EMR database to ensure seamless communication.
-
-
ETL Automation Testing:
-
Automated the validation of data pipelines for data transformation processes.
-
Created custom scripts to test the accuracy of data ingestion, transformation, and loading between the healthcare provider’s databases and third-party systems, ensuring no data loss or corruption.
-
Validated end-to-end ETL workflows that synchronize patient records across hospital systems, ensuring the integrity of patient data post-transformation.
-
Automated data quality checks that are triggered after every deployment, detecting discrepancies between source and destination databases early in the process.
-
-
Load Testing:
-
Conducted load and performance testing to simulate high-traffic scenarios and measure system responsiveness under stress.
-
Tested high-volume transaction scenarios during peak usage periods (e.g., flu season, emergency outbreaks) to ensure the platform’s stability.
-
Monitored response times, throughput, and error rates under different load conditions, helping optimize backend services and database queries.
-
-
Custom Reporting Tool for Client Visibility:
-
Developed a custom reporting tool that consolidated data from all automated tests (UI, API, ETL, load) and generated clear, client-friendly reports.
-
The tool provided real-time visibility into test results, highlighting successes, failures, and performance metrics for key user scenarios.
-
Integrated the reporting tool with Jenkins CI pipeline, allowing clients and internal teams to monitor test outcomes after each release.
-
Implemented interactive dashboards for tracking long-term trends in test stability, system performance, and data quality over multiple releases.
-
-
Continuous Integration (CI) Pipeline Integration:
-
Integrated all automated testing frameworks into the Jenkins CI pipeline, enabling continuous testing across multiple environments with every code commit.
-
Provided detailed test reports, which were embedded into the CI pipeline to give developers and QA teams immediate feedback on failed tests and performance issues.
-
Outcome and Metrics of Success:
-
Enhanced Test Coverage:
-
Achieved over 95% automated test coverage for critical user workflows, ensuring that both the web and mobile applications were thoroughly tested across different devices and browsers.
-
-
Reduced Testing Time:
-
Regression testing time decreased by 75%, from several days to a few hours, allowing for faster and more reliable feature deployments.
-
-
Improved System Reliability:
-
Load testing results identified and resolved bottlenecks, leading to improved system stability under peak traffic conditions, ensuring seamless operation during emergencies.
-
-
Data Integrity and Compliance:
-
Automated API and ETL testing ensured secure, accurate synchronization of patient data across systems, complying with HIPAA regulations and other healthcare standards.
-
-
Real-Time Client Reporting:
-
The custom reporting tool gave clients and stakeholders real-time visibility into testing outcomes, enhancing transparency and building trust with the development team.
-
-
