Introduction to GraphQL Testing

Introduction

Application testing is essential when creating an application. Testing is used to make sure the application is implemented correctly and can be used effectively without any bugs or defects.

Testing example with apitest

To understand how to test the GraphQL application, we create a test for a simple GraphQL application.

To test the GraphQL application, the apitest library is installed to create suitable test cases for the GraphQL application.

To create a test, we add a file called server_test.go in the root directory or the same location as the server.go file. Before creating a test, we create a helper called graphQLHandler() to return the handler from the GraphQL application.
