Testing Hack with Hammock - Riya Dashoriya - PHP UK 2020

Important concepts

• Hammock and Mockery are two different mocking libraries used for testing
• Hammock supports type-safe, performant and flexible testing
• Mockery’s shortcomings include:
  • Verbose and fluent syntax
  • Heavy performance overhead
  • Limited flexibility and scalability
  • No support for advanced features like async functions
• Using mocks sparingly and correctly can lead to better test performance and effectiveness

Best practices

• Mock specific functions or methods instead of whole classes
• Use disposable interfaces to limit the scope of mocking
• Avoid over-engineering and focus on simplicity
• Utilize Hammock’s features to speed up testing and improve code coverage

Language-specific considerations

• Hacklang is a dynamic programming language designed for better performance and reliability
• It has features like async functions and improved type checking
• Hack can be called into PHP and vice versa, supporting a high degree of interoperability

Open-source contributions

• The community advocate behind Hammock highlights the importance of open-source contributions
• Recognizes the efforts of Lexeter, the lead developer of Hammock
