// Feature Flag & Dark Launch Validation Services
// What Breaks When Feature Flags Are Untested
Wrong User Segmentation
A flag evaluates for the wrong cohort, leaking a feature to users who were never supposed to see it.
Cached Flag State
Stale flag values served from CDN or edge cache long after a toggle changed, confusing users and support alike.
Rollback Path Failure
The kill switch that's never been tested doesn't actually work at 2am during a real incident.
Our feature flag testing validates rollout logic and rollback paths before either one reaches real users.
// What Jignect Validates in Feature Flag Workflows
Flag Logic Correctness
Flag evaluation validated per user, group, and percentile against your SDK of choice.
Dark Launch Stability Testing
New code paths tested without user exposure, measuring latency and error rate impact even while the flag is off.
Canary Deployment Validation
Staged rollout of flag-gated feature versions validated with automated traffic routing.
Rollback Path Verification
Actual rollback scenarios simulated in staging so kill switches execute cleanly under load.
// Integrated Tool Ecosystem
// Deliverables, Not Just a Pass/Fail
Flag Audit & Dependency Map
A full inventory of active flags and everything each one touches.
Automated Flag Evaluation Suite
Tests covering every flag state combination, wired into your CI/CD.
Dark Launch & Rollout Monitoring
Latency and error rate tracked on new code paths before they're ever exposed.
Rollback Simulation & Retirement
Kill switches drilled under load, and stale flags flagged for cleanup.

Who is Feature Flag Testing built for?
It's built for teams whose rollout percentage doesn't match who's actually seeing a feature; teams serving stale flag state from CDN or edge cache; teams whose kill switch has never been tested under real load; and teams accumulating stale flags nobody remembers to retire.
What's the difference between feature flag testing and A/B testing?
Feature flag testing validates the infrastructure and control logic of flags, correct evaluation, rollout accuracy, and state transitions. A/B testing measures user behavior under different flag states, and depends on flag infrastructure being solid underneath.
Do you test with real feature flag platforms like LaunchDarkly?
Yes. We integrate directly with LaunchDarkly, Split.io, Unleash, Flagsmith, ConfigCat, or your platform's SDK, testing actual targeting rules and rollout percentages in your environment.
How do you test rollback paths without triggering them in production?
We replicate your environment in staging, enable the flag, then simulate rollback scenarios, validating that traffic re-routes correctly and dependent services recover under load.
Can you validate dark launches without user impact?
Yes. Dark launch testing runs the new code path in parallel with the old one, comparing latency, error rate, and resource consumption without surfacing differences to users.
How do you detect stale or orphaned flags?
AST analysis scans for unreferenced flag evaluations, coverage metrics flag untested flags, and platform analytics spot flags with zero impressions over 30-plus days, then we automate retirement.
What does a typical feature flag testing engagement look like?
Flag inventory and test planning, then automated evaluation suite setup, dark launch and canary testing, rollback drills, and ongoing quarterly flag audits.
