Quick bootstrapping for testing GraphQL Resolvers

Animal.test.js

// graphql/types/Animal/Animal.test.js

import * as AnimalResolvers from './Animal.resolvers.js';

export const animalNameTest = () => {
    const obj = {
      kind: 'Dog',
      name: 'Koko',
      breeds: ['Corgi', 'German Shepherd']
    };
  
    const args = {};
    const ctx = {};

    const output = AnimalResolvers.name(obj, args, ctx);

    expect(output).toEqual('Koko');
};

resolvers.test.js

// graphql/types/resolvers.test.js

import glob from 'glob';
import path from 'path';

const basePath = path.join(process.cwd(), './graphql/types/');

describe('Resolvers', () => {
  // Find all our resolver files
  const files = glob.sync(`${basePath}**/*.test.js`);
  
  files.forEach(file => {
    describe(file, () => {
      const resolvers = require(file);

      Object.entries(resolvers).forEach(([name, fn]) => {
        it(name, () => Promise.resolve(fn()));
      });
    });
  });
});
