🚀 Buzz.js 🌚

Buzz.js is a simple tool to help you mock GraphQL responses in your components that use Apollo's useQuery and useMutation hooks.

Installation

1. Install buzz

   $ yarn add -D @sonder/buzz.js
   

2. Update your jest configuration to add a setup file to setupFilesAfterEnv

   // package.json
   ...
   "jest": {
       "setupFilesAfterEnv": [
           "jest/buzz.js" // 👈 add this
       ]
   }
   

3. Load your local schema file onto the spaceship:

   // jest/buzz.js
   import moment from "moment";
   
   import { loadSchemaFile, resetMocks, setMocks } from "@sonder/buzz.js";
   
   beforeAll(() => {
     loadSchemaFile("./schema.graphql"); // Relative path from the root of your workspace
   
     // Optional: Mock out nonstandard scalar types in your schema
     setMocks({
       RFC3339DateTime: () => moment().format(),
     });
   });
   
   afterEach(() => {
     resetMocks();
   });
   

4. Use it in your tests! Buzz is compatible with any DOM mocking library, including Enzyme and React Testing Library.
