Feature Flags

This page outlines the QA role in ensuring that toggled features behave as expected under all flag states and in every environment.

Feature flags (aka feature toggles) enables project teams to release new features gradually, conduct A/B testing, control feature access, and test in production without immediately enabling it for all end users. Testing with feature flags can activate and deactivate the features for specific users, environments or conditions. This way, we reduce risk and offer modern approach of rollout strategies for our customers.

Why Testing Feature Toggles?

We test that features respond correctly when toggled on/off:

• UI elements appear/disappear as expected
• APIs and logic behind the feature are gated
• Fallback behavior works (e.g. old version loads if flag is off)

QA ensures all relevant scenarios in both enabled and disabled states are validated.

What QA Validates with Feature Flags?

• Targeting rules are respected (specific users, staging vs production, app version, roles, etc.)
• Analytics & event tracking work for both A and B variations (A/B testing)
• UI is consistent and follows UX guidelines for both toggle conditions
• Configuration & flag management (default values, flags not persisting due to stale cache, etc.)

Feature Toggle Tools We Support

• Flagd - Local/remote flag service
• OpenFeature - Open standard for feature flag management
• Firebase Remote Config - Often used in mobile and web apps
• LaunchDarkly, Unleash , or custom toggle systems

QA interacts with feature flags mainly via:

• Admin UI (if available)
• API config
• Environment variable overrides
• Emulator/console overrides in dev builds

Conclusion

QA ensures every flag-controlled feature is reliable, measurable, and safely rolled out — no matter how complex the targeting logic or environment setup. If it’s toggled, we always test both sides.
