Regression testing built for
continuous change
Ensure new changes never break what already works. Ship with confidence that existing functionality remains intact.
Why regressions happen at scale
Most production bugs are regressions. Changes break things far from where they are made, and traditional testing cannot keep pace with continuous delivery.
Changes impact distant parts of the system
A small update in one service cascades to unexpected failures elsewhere. Dependencies are invisible until something breaks.
Incomplete coverage of existing behavior
Legacy functionality is undertested. Critical paths that worked for years break silently when unrelated code changes.
Manual regression cycles slow releases
Teams wait days for manual QA cycles. Velocity drops, or teams skip regression entirely and hope for the best.
Feature velocity outpaces test maintenance
New features ship faster than tests are updated. Regression coverage erodes as the codebase grows.
Hidden dependencies across services
Microservices depend on implicit contracts. A refactor in one service breaks consumers that no one remembered.
Customer-facing breakages after "successful" releases
All tests pass, but customers report broken functionality. Regressions slip through the cracks every release.
How Zof prevents regressions
Change-aware validation that protects existing functionality. Built for the pace of continuous delivery.
Automated validation of existing behavior
Every change is validated against existing functionality. Catch behavioral regressions before they reach production.
Continuous coverage as systems evolve
Regression coverage adapts as your system changes. No maintenance burden, no coverage drift over time.
Focus on critical workflows and high-risk areas
Prioritize validation on revenue-critical paths and frequently changing code. Test what matters most.
Detection of unintended side effects
Identify behavioral changes in seemingly unrelated code paths. Catch the regressions that traditional tests miss.
Confidence before changes reach production
Know that existing functionality remains intact. Ship features without fear of breaking customer workflows.
Regression testing in the enterprise testing system
Regression testing validates what already works. Zof orchestrates it as part of a comprehensive, unified testing platform.
Validates what already works
While other tests verify new functionality, regression testing ensures existing behavior remains unchanged across releases.
Complements existing test layers
Works alongside unit, integration, API, and E2E testing. Adds the change-safety layer that prevents existing functionality from breaking.
Unified orchestration
Zof runs regression validation as part of a single, unified platform. No fragmented tooling, no maintenance overhead.
Ensures every change is safe
Built for teams that ship frequently
From engineering leadership to release teams, change safety is everyone's responsibility.
Engineering Leaders
Confidence to ship fasterMove quickly without fear of breaking what works. Empower teams to ship features knowing existing functionality is protected.
Release Teams
Fewer rollbacks and hotfixesReduce emergency fixes after releases. Catch regressions before deployment, not from customer escalations.
QA Teams
Scalable regression coverageMove beyond manual regression cycles. Automated coverage that grows with the system, not the headcount.
Enterprise Organizations
Stable customer experienceProtect existing customer workflows across every release. Maintain trust with reliable, regression-free deployments.
Regression validation flow
From code change to safe release. Every deployment validated against existing functionality.
