CONTEXT

Verve Square was engaged by a large US-based hospitality chain to carry out performance testing and engineering as part of a significant transformation program. This program involved migrating from a monolithic architecture to an event-based architecture and moving over 40 applications to AWS.

Challenges

  • Lack of existing benchmarks to compare performance.
  • No pre-defined Non-Functional Requirements (NFRs) for performance testing.
  • The client's existing LoadRunner tool licenses were set to expire.
  • No comparable integrated performance test environment was available.

Solution

  • Gathered performance metrics and statistics to establish NFRs.
  • Conducted benchmark tests on the existing environment.
  • Migrated existing performance test scripts to NeoLoad, replacing LoadRunner.
  • Collaborated with architects to create extrapolation formulas to compare test results with production.
  • Employed service virtualization to test components early in the development cycle.
  • Built virtual services to enable early performance testing when backend systems were unavailable.

Value Delivered

  • Successfully migrated 30 application performance test scripts from LoadRunner to NeoLoad.
  • Collaborated with multiple teams, including vendors, to establish and validate NFRs.
  • Tested the system at 1200 transactions per second (TPS) for future scalability.
  • Established reusable performance testing standards and tools across the enterprise, resulting in cost savings.
  • Integrated performance testing into the CI/CD pipeline by developing Jenkins jobs for automation.
