A tool for API mocking and simulation

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

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

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.

Key differences between API mocking and API simulation

Feature	API Mocking	API Simulation
Purpose	Stub specific API responses	Create a comprehensive API replica
Scope	Simple unit and integration testing	Sandbox creation, load, performance and consumer testing
Complexity	Simpler	More intricate
State Management	Minimal	Often required
Data manipulation	Basic	Complex

Hoverfly excels at both mocking and simulation. It provides a flexible platform for creating simple mocks or complex API simulations. This versatility makes it a valuable tool for development teams of all sizes.
