//! E2E Tests: Next.js Ontology Package - Concurrent Test Suite
//!
//! This test suite validates the complete lifecycle of the Next.js ontology marketplace package
//! through independent, concurrent test functions. Each test creates its own isolated container
//! and can run in parallel without interference.
//!
//! **Test Organization**:
//! - Each test is independent with its own container
//! - Tests can run concurrently (cargo test runs them in parallel by default)
//! - Each test verifies a specific facet of the package lifecycle
//! - All tests use chicago-tdd-tools patterns
//!
//! **Test Coverage**:
//! - Setup and build verification
//! - Package installation and structure validation
//! - Code generation and file verification
//! - Type checking and build validation
//! - Ontology modification and regeneration
//! - Idempotency verification
//! - **Expert Patterns**: Error paths, boundary conditions, resource cleanup
//!
//! Uses chicago-tdd-tools testcontainer API for complete container isolation.
//!
//! **Expert Testing Patterns Applied** (80/20 Rule):
//! - Error Path Testing: Invalid package names, missing packages, installation failures
//! - Boundary Condition Testing: Empty ontologies, edge cases, maximum sizes
//! - Resource Cleanup Testing: Container isolation, partial installation rollback
//! - Concurrency Testing: Multiple concurrent installs (via parallel test execution)

#![allow(clippy::expect_used)] // Tests can use expect for clarity
#![allow(clippy::unwrap_used)] // Tests can use unwrap for brevity
