Integration tests with test server in GraphQL - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the test server before running tests.

GraphQL

beforeAll(async () => { await server.[1](); });

Drag options to blanks, or click blank then click option'

Astart

Bstop

Crestart

Dinit

Attempts:

3 left

💡 Hint

Common Mistakes

Using stop instead of start will shut down the server before tests.

The start method launches the test server so tests can run against it.

2fill in blank

medium

Complete the code to send a GraphQL query to the test server.

GraphQL

const response = await server.executeOperation({ query: [1] });

Drag options to blanks, or click blank then click option'

Amutation

BGET_USERS_QUERY

Csubscription

DDELETE_USER_MUTATION

Attempts:

3 left

💡 Hint

Common Mistakes

Passing a mutation or subscription instead of a query.

You need to pass the GraphQL query string or document. GET_USERS_QUERY is the correct query here.

3fill in blank

hard

Fix the error in the test assertion to check the response status code.

GraphQL

expect(response.[1]).toBe(200);

Drag options to blanks, or click blank then click option'

CstatusCode

Dstatus

💡 Hint

Common Mistakes

Using statusCode or code which are not standard in this context.

The correct property for HTTP status in the response is status.

4fill in blank

hard

Fill both blanks to correctly close the test server after all tests.

GraphQL

afterAll(async () => { await server.[1](); await server.[2](); });

Drag options to blanks, or click blank then click option'

Astop

Bclose

Cstart

Drestart

Attempts:

💡 Hint

Common Mistakes

Using start or restart instead of stop or close.

First, stop the server, then close any open connections.

5fill in blank

hard

Fill all three blanks to write a test that sends a mutation and checks the response data.

GraphQL

test('adds a user', async () => {
  const response = await server.executeOperation({
    query: [1],
    variables: { name: [2] }
  });
  expect(response.data.[3]).toBeDefined();
});

Drag options to blanks, or click blank then click option'

AADD_USER_MUTATION

B'Alice'

CaddUser

DGET_USER_QUERY

Attempts:

3 left

💡 Hint

Common Mistakes

Using a query instead of mutation, missing quotes around name, or wrong response field.

The mutation is ADD_USER_MUTATION, the variable name is the string 'Alice', and the response field is addUser.
