Cross-browser report validation and API testing to deliver zero-issue migration
A diagnostic technology provider upgraded its LIMS print service and migrated it to Azure using App Service, Blob Storage, and Queue Storage. The program required functional testing, multi-format report testing across browsers, and API validation to ensure a smooth transition for existing and new clients. CES implemented a structured testing strategy with end-client environment replication and real-time customizations, enabling a zero-issue migration and a reusable model for future service migrations.

the impact
Zero post-production issues after migration
Seamless migration experience for end clients
Reusable test strategy for future service migrations
High confidence through replicated client environments
The shift was test-strategy-led.
The result: zero post-production issues.
The Need
The LIMS print service was being upgraded and hosted on Azure with App Service, Blob Storage, and Queue Storage, along with required application enhancements. The business needed complete validation of functionality, report outputs (physical and soft copies), browser compatibility, and API correctness to ensure migration continuity for both existing and new clients.
Challenges
- Multi-format report validation across browsers (physical + soft copies): Numerous report types and formats required validation across browsers, including physical and soft-copy outputs, to prevent client-facing issues post-migration.
- End-to-end functional testing during LIMS print service upgrade and Azure migration: The upgraded print service and application enhancements needed thorough functional coverage to support a smooth transition for all client scenarios.
- API testing to confirm interfaces remained intact for existing and new clients: APIs had to be tested to confirm interfaces remained accurate and consistent through the Azure migration, supporting both existing and new client onboarding.
- Comprehensive testing strategy and execution: Planned and executed a structured test strategy covering application functionality and migration readiness.
- Report testing across formats and browsers: Validated physical report outputs and soft-copy reports across multiple report types, formats, and browsers using cross-browser testing.
- API testing for interface integrity: Performed API testing to ensure service interfaces remained intact and accurate after the upgrade and migration.
- End-client environment replication: Replicated the end-client environment, including real-time customizations, to validate post-migration behavior with higher confidence.
- Migration completed successfully with zero post-production issues for all end clients.
- Testing approach delivered high confidence in post-migration stability, supported by replicated client configurations and customization coverage.
- Created a reusable test strategy for future migrations of the print service or similar services.
