API and test-data automation

Quality Assurance CoE

83% reduction in API evaluation cycle time

Business problem

Monthly service releases required manual evaluation of individual services and API collections. New combinations and integrations increased data-setup effort every cycle.

Engagement context

  • 128 API collection sets
  • 2 functional resources per cycle
  • ~80 hours per release (~5 days)
  • Execution rate: ~1.6 tests per hour
  • Test data preparation: ~12 hours per release

Solution implemented

Phase 1 — Automated test data

Automated creation of test data used across API collections and related functional tests (~160 hours, one dedicated resource).

Phase 2 — API collection automation

Automated execution of collection sets aligned to release needs (~368 hours).

Outcomes

  • 83% reduction in API evaluation cycle time
  • Test data preparation effort reduced materially for functional testing as well
  • More predictable monthly release validation

Automating data first, then collections, removed the highest-friction manual steps in the release path.
