Create mocks of your GraphQL Schema

easygraphql-mock

easygraphql-mock is a node library used to create mocks of a schema. It will create mocks of all the types that are on the GraphQL Schema, including the nested types.

Installation

To install the package on your project just run on the root of your project

$ npm install easygraphql-mock --save

How to use it?

• Import easygraphql-mock package.
• Read the schema.
• Initialize the mock, and pass the schema as the first argument.
  • If there are multiples schemas pass an array with the schemas an argument.
  • Note: In order to use multiples schema files, the queries and mutations must be extended.
• The second argument is optional and it is going to be your custom schema, in case you want to pass it.

In case you have a custom scalar, set it on the second argument, if it's not set it will be {}

One schema file

'use strict' 

const easygraphqlMock = require('easygraphql-mock')
const fs = require('fs')
const path = require('path')

const userSchema = fs.readFileSync(path.join(__dirname, 'schema', 'user.gql'), 'utf8')

const mockedSchema = easygraphqlMock(userSchema)

Multiples schemas files

'use strict' 

const easygraphqlMock = require('easygraphql-mock')
const fs = require('fs')
const path = require('path')

const userSchema = fs.readFileSync(path.join(__dirname, 'schema', 'user.gql'), 'utf8')
const familySchema = fs.readFileSync(path.join(__dirname, 'schema', 'family.gql'), 'utf8')

const mockedSchema = easygraphqlMock([userSchema, familySchema])

Custom schema

You can set some values to the fields that you want on the schema. To do that, you might pass an object as a second argument. It must have the same name of the type and the field that you want to set.

'use strict' 

const easygraphqlMock = require('easygraphql-mock')
const fs = require('fs')
const path = require('path')

const userSchema = fs.readFileSync(path.join(__dirname, 'schema', 'user.gql'), 'utf8')
const familySchema = fs.readFileSync(path.join(__dirname, 'schema', 'family.gql'), 'utf8')

const mockedSchema = easygraphqlMock([userSchema, familySchema], {
  CustomScalarDate: '2018-10-10',
  Family: {
    name: 'Super test 1',
    ages: [10],
    familyRelation: 'Mother',
    familyRelationArr: ['Mother', 'Brother']
  }
})

Result

Here is the result of mockedSchema.Family

{ 
  name: 'Super test 1',
  ages: [ 10 ],
  createdAt: '2018-10-10',
  user: { 
    email: '[email protected]',
    username: 'tNfwN',
    fullName: 'Nathan Lewis',
    phone: '[phone]',
    family: { 
      name: 'Super test 1',
      ages: [ 10 ],
      user: { 
        email: '[email protected]',
        username: 'tNfwN',
        fullName: 'Nathan Lewis',
        phone: '[phone]',
        family: '...'
      },
      familyRelation: 'Mother',
      familyRelationArr: [ 'Mother', 'Brother' ] 
    }
  },
  familyRelation: 'Mother',
  familyRelationArr: [ 'Mother', 'Brother' ] 
}
