    fetch-mock

    Mock http requests made using fetch.

    Features include:

    • mocks most of the fetch API spec, even advanced behaviours such as streaming and aborting
    • declarative matching for most aspects of a http request, including url, headers, body and query parameters
    • shorthands for the most commonly used features, such as matching a http method or matching one fetch only
    • support for delaying responses, or using your own async functions to define custom race conditions
    • can be used as a spy to observe real network requests
    • can be extended with your own reusable custom matchers that can be used both for matching fetch-calls and inspecting the results
    • isomorphic, and supports either a global fetch instance or a locally required instance

    New If using jest, try the new fetch-mock-jest wrapper.
