Mocks Plugin

A simple plugin for adding resolver mocks to a graphQL schema.
Usage
Install
yarn add @giraphql/plugin-mocks
Setup
import MocksPlugin from '@giraphql/plugin-mocks';
const builder = new SchemaBuilder({
    plugins: [MocksPlugin],
});
Adding mocks
You can mock any field by adding a mock in the options passed to builder.builSchema under mocks.{typeName}.{fieldName}.
builder.queryType({
    fields: (t) => ({
        someField: t.string({
            resolve: () => {
                throw new Error('Not implemented');
            },
        }),
    }),
});
​
builder.toSchema({
    mocks: {
        Query: {
            someField: (parent, args, context, info) => 'Mock result!',
        },
    },
});
Mocks will replace the resolve functions any time a mocked field is executed. A schema can be build multiple times with different mocks.
Adding mocks for subscribe functions
To add a mock for a subscriber you can nest the mocks for subscribe and resolve in an object:
builder.subscriptionType({
    fields: (t) => ({
        someField: t.string({
            resolve: () => {
                throw new Error('Not implemented');
            },
            subscribe: () => {
                throw new Error('Not implemented');
            },
        }),
    }),
});
​
builder.toSchema({
    mocks: {
        Subscription: {
            someField: {
                resolve: (parent, args, context, info) => 'Mock result!',
                subscribe: (parent, args, context, info) => {
                    /* return a mock async iterator */
                },
            },
        },
    },
});
