Mock http requests made using fetch
npm install fetch-mockFeatures 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
@fetch-mock requires either of the following to run:
- Node.js 18+ for full feature operation
- Any modern browser that supports the fetch API
- node-fetch when testing in earlier versions of Node.js (this is untested, but should mostly work)
