Common Use Cases

Discover how MockQL solves everyday development challenges and improves your workflow with these practical use cases.

Develop Against Unfinished APIs

Continue frontend development even when backend APIs aren't ready yet. Add new fields or entirely new endpoints to match your needs.

Example Scenario:

Your team is building a new user profile page that requires additional data like user roles and permissions, but the backend API update is scheduled for next month. With MockQL, you can extend the existing API response with the fields you need right now.

Debug Faster with Controlled Responses

Quickly test how your application handles different API responses without waiting for backend changes.

Error States

Test your app's handling of 400, 401, 404, and 500 error responses

Edge Cases

Simulate empty data, malformed responses, and unusual content

Loading States

Test with different response times from instant to very slow

Work Offline & Handle Outages

Keep developing even when backend services are unavailable, experiencing downtime, or undergoing maintenance.

When This Helps:

  • During unexpected backend service outages

  • When working remotely with unreliable internet

  • During planned backend maintenance windows

More Specialized Use Cases

Error Testing

Systematically test how your application handles various error scenarios.

Test validation errors, authentication failures, permission issues, and server errors with just a configuration change.

Performance Testing

Simulate different network conditions to test app performance.

Test how your UI performs under fast 5G, average 4G, slow 3G, or extremely poor network conditions.

Security Testing

Test your application's security controls with modified responses.

Simulate tampered authentication tokens, permission escalation scenarios, and unauthorized access attempts.

Device Testing

Adapt responses for different device types and capabilities.

Test with device-specific data like different image resolutions, mobile-optimized data, or feature availability.

Why Teams Use MockQL

MockQL dramatically improves development efficiency, application quality, and team collaboration by solving these common challenges.

Faster Development

Reduce dependencies between teams and eliminate waiting time

Better Testing

Test edge cases and error scenarios that are hard to reproduce

Improved Resilience

Build applications that handle unexpected conditions gracefully
