Why banks choose Karate

Purpose-built capabilities for the unique demands of financial services testing.

100% Local

Your test data, credentials, and API keys never leave your network. No cloud round-trips.

Kafka & Event-Driven

Native Kafka testing with Avro, consumer groups, and SASL. Test event-driven banking pipelines alongside REST.

Microservices at Scale

Component testing for 50+ service architectures. Isolate services, mock dependencies, gate builds on coverage.

Contract Testing

JSON schema validation in 1-2 lines. Ensure no service breaks the contract with another — critical when dozens of teams deploy independently.

GFT webinar - Streamlining Core Banking with Karate

GFT built shift-left component testing for a Tier-1 US bank's 50+ microservice core banking migration — embedding Kafka, databases, and AWS services locally so developers could test in complete isolation.

  • Embedded Kafka, PostgreSQL, and AWS services into local developer test suites
  • 50+ microservices tested in isolation with full dependency mocking
  • Shift-left testing reduced defect escape rate and accelerated release cycles
  • Single framework for API, Kafka, and database validation across the entire banking platform
