About:
Touca is an open-source regression testing tool that helps engineers validate their complex workflows and algorithms by capturing data from test cases and comparing it against a trusted baseline. It automatically detects differences in output, performance, and custom metrics, making it ideal for testing data pipelines, machine learning models, and scientific code. This allows teams to ship faster with confidence, knowing exactly what changed and why.

Key Features:

Automated regression detection for data and performance
Visual diffing for complex data types and objects
Seamless integration with CI/CD pipelines
Versioning and historical tracking of test results
Collaborative reporting for team workflows

Use Cases:

Regression testing for machine learning models
Validating scientific computing and data processing pipelines
Performance benchmarking of algorithms
End-to-end testing of backend services

Alternatives:

pytest – pytest is a general-purpose unit testing framework, whereas Touca specializes in capturing and comparing data outputs for regression testing.
Weights & Biases – W&B focuses on experiment tracking and model training, while Touca is designed for continuous regression testing of production code.
