//! Integration tests for 7sense bioacoustics platform
//!
//! This module organizes integration tests across all six bounded contexts:
//! - Audio Ingestion Context
//! - Embedding Context
//! - Vector Space Context
//! - Learning Context (via Analysis)
//! - Analysis Context
//! - Interpretation Context
//!
//! Tests are organized by context and follow the domain-driven design boundaries.
//!
//! Note: Individual test files (audio_test.rs, etc.) are compiled as separate
//! test binaries via [[test]] entries in Cargo.toml.

// Re-export commonly used test utilities
