Integration testing for
enterprise distributed systems
Validate system-to-system behavior before failures cascade. Catch contract violations and integration drift before production.
Why integrations fail at scale
Most critical production failures happen at system boundaries. Services evolve independently and break contracts silently.
Independent service releases break contracts
Teams deploy services independently. A schema change or behavior update silently breaks downstream consumers.
Undocumented API or schema changes
APIs evolve without contract updates. Consumers discover breaking changes in production, not in testing.
Third-party integrations change behavior
External APIs update without notice. Payment providers, auth services, and vendors break your flows.
Data mismatches across systems
Different services interpret data differently. Type coercion, missing fields, and format assumptions cause silent failures.
Environment-specific integration issues
Staging configurations differ from production. Integration behavior that passes tests fails in the real environment.
Cascading failures across dependencies
One service failure propagates through the dependency chain. Retry storms and timeout cascades take down entire systems.
How Zof validates integrations
Contract enforcement and boundary validation that catches the failures traditional testing misses. Built for distributed enterprise systems.
Automated validation of system interactions
Continuously verify how services communicate in real scenarios. Validate request/response behavior, error handling, and edge cases across every integration point.
Contract and data exchange verification
Ensure data flows correctly between systems. Validate schemas, type compatibility, and transformation accuracy at every service boundary.
Coverage across internal and external systems
Validate both your microservices and third-party integrations. Payment providers, auth services, and partner APIs are tested with the same rigor.
Detection of integration regressions
Catch when a service update breaks downstream consumers. Identify behavioral changes that pass unit tests but fail in integration context.
Continuous validation as systems evolve
Every code change triggers integration validation. No more hoping integrations still work after deployment.
Built for enterprise complexity
Not simple connectivity checks. Infrastructure that validates your distributed systems work together reliably.
Designed for distributed, multi-service systems
Handles architectures with hundreds of services. Understands dependency chains, data flows, and interaction patterns across your entire platform.
Handles internal and third-party integrations
Validates both your microservices and external dependencies. Payment gateways, auth providers, and partner APIs tested with production-level rigor.
Scales with system complexity and growth
From 10 services to 1,000. Integration validation that grows with your architecture without increasing maintenance burden or slowing deployments.
Reduces outages caused by integration failures
Prevent the production incidents that happen when services interact. Contract violations caught before they cascade into customer-facing outages.
Built for teams that own system boundaries
From platform engineers to QA leadership, integration reliability is a shared responsibility across engineering.
Platform Teams
Safer system evolutionDeploy platform changes with confidence that service contracts remain intact. Catch breaking changes before they affect dependent teams.
Backend Engineers
Fewer integration surprisesKnow immediately when your changes break other services. Validate integrations in development, not after production incidents.
QA Teams
Broader system coverageExtend testing beyond individual services to validate real system interactions. Catch the failures that unit and API tests miss.
Enterprise Organizations
Reduced incident blast radiusPrevent cascading failures that take down multiple systems. Integration validation contains issues before they propagate.
Integration validation flow
From system change to validated results. Continuous contract enforcement at every boundary.
