Multi-Tenancy and Data Isolation

Users can only access their own organization's data

Team member invitations work correctly

Invite new members by email and verify they can join the correct organization with appropriate permissions.

Role-based access control is enforced

Test each user role to verify they can only access features and data appropriate to their permission level.

Organization settings are isolated

Change settings for one organization and verify the changes do not affect other organizations.

API endpoints respect tenant boundaries

Attempt to access another tenant's resources through API calls to verify proper authorization checks.

Subscription and Billing

Plan selection and upgrade work correctly

Subscribe to different plans and verify that features, limits, and pricing reflect the selected plan accurately.

Usage limits are enforced per plan

Exceed plan limits and verify the app prevents further usage or displays appropriate upgrade prompts.

Billing page displays accurate information

Check that the billing dashboard shows the correct plan, next billing date, payment method, and invoice history.

Plan downgrade handles data correctly

Downgrade to a lower plan and verify that excess data or features are handled gracefully with clear messaging.

User Management

Admin can manage team members

Add, edit roles, and remove team members as an admin and verify each operation completes correctly.

Profile updates save correctly

Update user profile fields and verify changes persist and display correctly throughout the application.

Account deletion removes all user data

Delete a test account and verify that all associated data is removed or properly anonymized.

Activity logs track important actions

Perform key actions and verify they appear in audit logs or activity feeds with accurate timestamps.

Feature Reliability

Core features work consistently across sessions

Use main features across multiple sessions and days to verify consistent behavior and data persistence.

Data export produces correct output

Export data in all supported formats and verify the exported files contain accurate, complete information.

Webhooks and integrations fire correctly

Trigger events that should fire webhooks and verify the payloads are delivered with correct data.

Dashboard metrics and analytics are accurate

Compare dashboard statistics against actual data to verify that metrics compute and display correctly.

Frequently Asked Questions

How do I test multi-tenancy without real customer data?

Create multiple test organizations with different plans and roles. Populate each with sample data and test as different users to verify isolation. DidItWork.app testers can create these test scenarios systematically.

Should I test billing with real payment processors?

Use your payment processor's test mode. Stripe test mode, for example, lets you simulate successful payments, failed payments, and subscription lifecycle events without processing real charges.
