1//! Compliance Testing Suite for Standards Validation
2//!
3//! This module provides automated compliance testing capabilities to validate
4//! that evaluation implementations meet industry standards and specifications.
5//!
6//! # Features
7//!
8//! - **ITU-T Standards Testing**: Validate PESQ, POLQA, P.56 implementations
9//! - **ISO/IEC Compliance**: Test against ISO/IEC 23003-3 requirements
10//! - **ANSI Standards**: Validate ANSI S3.5 compliance
11//! - **AES Standards**: Audio Engineering Society standard compliance
12//! - **Automated Test Execution**: Run comprehensive test suites
13//! - **Certification Reports**: Generate compliance certification documents
14//! - **Regression Testing**: Ensure continued compliance across updates
15//!
16//! # Example
17//!
18//! ```rust
19//! use voirs_evaluation::compliance_testing::*;
20//!
21//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
22//! // Create compliance tester
23//! let tester = ComplianceTester::new();
24//!
25//! // Run PESQ compliance tests
26//! let pesq_results = tester.test_pesq_compliance()?;
27//!
28//! if pesq_results.compliant {
29//!     println!("PESQ implementation is compliant!");
30//! } else {
31//!     println!("PESQ compliance issues:");
32//!     for issue in &pesq_results.issues {
33//!         println!("  - {}", issue.description);
34//!     }
35//! }
36//! # Ok(())
37//! # }
38//! ```
