Introduction to REST API Testing

Introduction

Testing is an essential activity when creating an application. Testing ensures the implementation of the application is correct and that the application can be used effectively without any bugs or defects.

Testing example with apitest

To understand how to test the REST API application, we create a test for the simple API application that we have built.

To test the REST API application, we install a library called apitest. This library creates suitable test cases for the REST API application.

To create a test, we add a file called main_test.go in the root directory or the same location as the main.go file. Then, we create a test case to get all the book data.
