chai-fetch-mock

Chai plugin for fetch-mock library version 3.0.0. Provides Chai assertions for fetch-mock, a mocking library for fetch() and isomorphic-fetch. Active maintenance, weekly release cadence. Differentiator: adds fluent BDD-style assertions like `.called`, `.with.args()`, `.with.url()`, `.with.options()` for fetch-mock routes, requiring careful ordering with other Chai plugins. Supports Node.js 7+ and Chai 3.x/4.x, fetch-mock 5.1.x/6.x. Note: fetch-mock 6.0 requires Node >=7.
