API and UI Test Automation Reduced Regression Time by 65% for a Hospitality Provider

Travel & Hospitality
Posted On: 19 October, 2026

About the Client

The client is a leading firm in the hospitality industry, operating a chain of economy apartment hotels across the United States and Canada. It specializes in long-term accommodation for travelers and professionals.

Engagement Duration: Ongoing 
Industry: Travel & Hospitality

The Challenge

  1. The client was migrating from a legacy central reservation system (CRS) to a new platform, and guest bookings had to continue without disruption throughout the transition.
  2. Differences between the existing and replacement systems posed risks to reservation accuracy, and booking records had to be verified across both to prevent data inconsistencies.
  3. Testing across the website and partner integrations required broader coverage, while frequent releases left limited time for regression checks.
  4. Environment issues could delay deployment if detected late.

The Approach

Cybage established a dedicated QA automation team on an onshore-offshore delivery model, with a phased transition aligned to the client's CRS releases. The team first created a reference for existing API functionality and performance, providing a standard for assessing the replacement platform. Weekly discussions with the client's engineering team helped resolve issues and review test results.

The Solution

Automated Checks Across Both Reservation Systems
Karate automated functional and performance tests for the legacy CRS, the new CRS, and the client’s internal Experience APIs. Automated database checks compared reservation records across both systems and flagged mismatches during migration.


End-to-End Website Coverage
Using the Karate framework, the team built a UI regression suite for the website that covered critical reservation journeys such as booking and cancellation. Rate validation and less common scenarios extended coverage beyond standard user paths.


Load Benchmarking and ADA Compliance Checks
LoadRunner benchmarked critical APIs under load to confirm that the new platform maintained expected response times as demand increased. Axe-core was integrated into the framework to flag accessibility (ADA) issues earlier in development, with findings shared with business owners for corrective action.


CI/CD Integration and Environment Health Checks
Automated tests were built into the CI/CD pipeline and configured for each environment, so every weekly release candidate went through regression checks to support deployment decisions. Environment stability and health were verified before each release; surfacing problems before they could disrupt deployment.

The Impact

  • 65% reduction in regression time, bringing testing cycles from three to four hours down to approximately one hour.
  • 180+ automated test cases covering critical workflows and edge cases, with 98% of test scenarios automated and 99% API test coverage across all data combinations.
  • 90% of defects detected in lower environments, allowing teams to address issues earlier.
  • 3 releases per week supported, including independent and concurrent backend and frontend deployments.
  • 100% functionality and performance coverage on the new CRS APIs, with all legacy APIs baselined.
  • Full data validation through database automation, with environmental risks fully mitigated
