Post-upgrade Verification​


rust

#[cfg(test)]
mod upgrade_tests {
    use opencv::core;
    #[test]
    fn test_opencv_version() {
        let version = core::get_version_string();
        assert!(version.starts_with("4."));
        println!("OpenCV version: {}", version);
    }
    #[test]
    fn test_basic_functionality() {
        let mat = core::Mat::default();
        assert!(mat.empty());
    }
}

Rollback Procedures​

Quick Rollback

cp Cargo.lock.backup Cargo.lock
# Rebuild with previous versions
cargo build
# Verify functionality

cargo test​

Container Rollback

bash

# Rollback to previous image
kubectl set image deployment/opencv-app opencv-app=opencv-app:previous-version
# Monitor rollback
kubectl rollout status deployment/opencv-app
