Castle vs Smalltalk: The Verdict

⚡ Summary:

Castle: Castle is an open-source model-based testing framework for .NET that makes it easy to automate testing activities like implementing stubs and mocks, parameterizing tests, and sharing test context across tests.

Smalltalk: Smalltalk is an object-oriented, dynamically typed, reflective programming language. It was designed for incremental code development and testing, featuring an integrated development environment, a file system, and a system command shell. It paved the way for many IDE features that are now common in other languages.

Both tools serve their respective audiences. Compare the features, pricing, and user ratings above to determine which best fits your needs.
