test-multitenant-isolation

To test data isolation between tenants, you simulate cross-tenant access attempts and verify database query scoping to the correct tenant context. This involves executing deterministic tests with synthetic data to ensure cross-tenant activity access, API keys, and OAuth tokens are properly isolated.

Cross-tenant access testing verifies that attempts to access data across tenant boundaries are blocked by simulating requests with synthetic data. It validates mechanisms like API key isolation and OAuth token isolation to ensure users only access their own tenant's data.

You can verify query scoping enforcement by running a comprehensive test suite that checks all database queries are correctly scoped to the current tenant's context. This ensures schema changes or authentication middleware updates do not expose sensitive tenant information.

Yes, multi-tenant isolation testing covers API key isolation and OAuth token isolation. It verifies security-critical functionality through deterministic test execution using synthetic data to ensure these authentication tokens cannot access cross-tenant activity.

You should run multi-tenant data isolation tests after a database schema change or an update to the authentication middleware. This guarantees that no tenant's sensitive information has become accessible to another tenant due to the modifications.
