graph-spec v0.1.5

GraphSpec

GraphQL assertion and testing made easy

GraphSpec is a really simple GraphQL assertion library: it is mainly sugar over something really simple but repetitive to do otherwise.

Using GraphSpec, you can take any GraphQL schema, throw a query and have a deep validation of the query.

Installation

npm install --save-dev graph-spec

Example

In order to do some classic assertions (using mocha), you can use the default asserter:

import { queryAssert } from "graph-spec"
import mySchema from "./schema"

it("should say hello world", () =>
  queryAssert(mySchema, `
    query Test {
      hello
    }
  `, { hello: "Hello world!" })
)

it("should be able to greet in french", () =>
  queryAssert(mySchema, `
    query Test($greeting: String!) {
      hello(greeting: $greeting)
    }
  `, { hello: "Bonjour world!" }, {
    variableValues: {greeting: "Bonjour"},
  })
)

Note that you can pass in the options any of the following GraphQL-js options:

• rootValue
• contextValue
• variableValues
• operationName

For ease of use, you can create your own asserter, able to carry preset options:

import { createQueryAsserter } from "graph-spec"
import mySchema from "./schema"

const queryAssert = createQueryAsserter(mySchema, {
  rootValue: {user: "le monde"},
})

it("should say hello world", () =>
  queryAssert(`
    query Test {
      hello
    }
  `, { hello: "Hello le monde!" })
)

it("should be able to greet in french", () =>
  queryAssert(`
    query Test($greeting: String!) {
      hello(greeting: $greeting)
    }
  `, { hello: "Bonjour le monde!" }, {
    variableValues: {greeting: "Bonjour"},
  })
)
