Testing and Test Automation for a Complex Legacy Product Migration

A US-based dental management company offers business support and administrative services to nearly 1000 branded dental practices across the country. Their services support the clinics in providing dental care, urgent care, and medical aesthetics. Their management services include clinic administration, practice management, and technical support to enable clinics to serve patients effectively. They help the dental care facilities to build and strengthen their infrastructure, expertise, and competencies to improve patient care and drive growth.

The Challenge

The company has a legacy IBM AS/400 system to manage the infrastructure and services they provided. It was becoming difficult to add new and modern features and enhancements to the 30-year old system. It was also challenging to source skilled people and resources to maintain the software. The management team wanted to upgrade the system to .NET Core architecture, which requires transforming and testing the software against existing and new business requirements. While the company has an in-house testing team with functional testers, automation, performance, and release engineers, they realized that it was woefully understaffed to undertake testing at the required scale.

WHY NEWSCAPE

Newscape Consulting offers niche technical and domain-focused
solutions to healthcare companies. Newscape’s experience in testing
engagements covers creating test strategies, designing test
scenarios, frameworks, performance testing, and manual and automated
test execution..

Solution

The migration took over two years with complex issues to address. Newscape was appointed midway to the project when the scale of testing required far exceeded the company’s internal capacity. Newscape deployed a team of 5 experts, which the company soon ramped up to 12 for functional testing. The test lead and the business analyst from Newscape were experts in the dental health domain, while the rest of the team brought extensive experience and expertise in the healthcare domain.

The team started with CI /CD automation and improved the release management process to increase the frequency and stability of releases. They then automated a critical subset of smoke test cases covering about 5% of the functionality. Throughout the migration, the team performed manual regression testing and automated all the smoke test cases, eventually covering 20% of the functionality with test automation.

Newscape also did performance testing on ten most business-critical scenarios. The performance testing team created scripts to monitor the CPU and memory for any indication of performance degradation. They also set up a separate server and used JMeter for performance testing, flood.io for network load simulation from multiple regions, and Dynatrace for application monitoring.

The testing team created test cases based on the requirements, with occasional help from the development team to understand the implementation details. The QA engineers started the engagement by running 10 test cases per person per day as a baseline. They moved up to executing 25+ manual test cases per person per day, with additional automation capability.

As of this writing, the project is being piloted in one clinic, with rollout to all the facilities planned over the next six months.
