PROJECT HIGHLIGHTS

Client Context

A leading insurance provider undertook a modernization initiative to migrate its legacy APIs—predominantly built using Java (REST and SOAP)—to a new C#-based architecture. This large-scale migration spanned 564 APIs across core insurance functions like policy management, claims, endorsements, and customer servicing, involving comprehensive CRUD operations.

Challenges

  • Validate the functional accuracy and consistency of 564 APIs across both REST and SOAP

  • Legacy testing framework built with SpecFlow supported only REST APIs and lacked flexibility

  • Limited reusability and high effort in creating new automated test scripts

  • Need to align automation closely with ongoing sprints for faster releases

Solution Delivered

Qeagle engineered a robust API automation framework leveraging Reqnroll, replacing the older SpecFlow-based setup. The framework was tailored to support both REST and SOAP services and was designed with a capability-driven approach to accelerate test script development and support in-sprint automation.

Key Features:

  • Seamless migration from SpecFlow to Reqnroll with minimal downtime
  • Unified validation approach with response and schema checks
  • Modular components to reduce script creation and maintenance time
  • Agile-aligned automation model ensuring faster feedback loops
