Hoverfly is a powerful tool that can be used for both API mocking and API simulation. While these terms are often used interchangeably, they represent distinct approaches with different levels of complexity and application.
Hoverfly can handle both seamlessly with its user-friendly platform for creating simple over the wire mocks and complex API simulations. Developers can define specific mock responses to individual API calls or create a comprehensive virtual API sandbox environment. This flexibility makes Hoverfly Cloud an asset for any development team looking to optimise their testing process, or accelerate development.
API mocking simulates specific behaviours of an API for simple dev and testing purposes. It is typically used for unit or integration testing and is often simpler, providing predefined responses to specific requests.
API simulation creates a more comprehensive replica of an API, including multiple variations of endpoints and complex interactions. It can be used for broader testing scenarios, such as load testing, performance testing, and consumer testing. API simulation is more intricate, often involving state management and complex data manipulation, and allowing for more advanced API features like callbacks.
