scim-server 0.5.3

//! Provider-Specific Integration Tests
//!
//! This module contains comprehensive integration tests for specific provider implementations
//! of the multi-tenant SCIM system. Each provider type gets its own test suite to verify
//! provider-specific behavior while ensuring compliance with the MultiTenantResourceProvider trait.
//!
//! ## Test Organization
//!
//! ### Stage 3a: In-Memory Provider (`in_memory.rs`)
//! - Production-ready in-memory provider with tenant isolation
//! - Thread-safe concurrent operations
//! - Memory usage and performance testing
//! - Configurable capacity limits and persistence
//!
//! ### Stage 3b: Database Provider (`database.rs`)
//! - SQL database provider with different isolation strategies
//! - Schema-per-tenant, table-per-tenant, and row-level security
//! - Transaction support and connection pooling
//! - Migration and schema management
//!
//! ### Stage 3c: Cloud Platform Providers
//! - AWS Cognito provider (`aws_cognito.rs`)
//! - Azure AD provider (`azure_ad.rs`)
//! - Google Workspace provider (`google_workspace.rs`)
//!
//! ## Testing Strategy
//!
//! Each provider implementation must:
//! 1. Implement the MultiTenantResourceProvider trait correctly
//! 2. Ensure complete tenant data isolation
//! 3. Handle provider-specific error scenarios
//! 4. Support concurrent multi-tenant operations
//! 5. Provide appropriate performance characteristics
//!
//! ## Common Test Patterns
//!
//! All provider tests follow these patterns:
//! - Tenant isolation verification
//! - Performance under concurrent load
//! - Error handling and recovery
//! - Provider-specific feature testing
//! - Configuration and lifecycle management
