Background

I’ve secured my Dog REST API using Basic Authentication with Spring Security.

Problem

Now I want to create a unit test and an integration test for my API, but I have two problems with them:

How do I put in the username and password

I got the error below when I ran the unit test:

What’s wrong

For the second problem, The error was occurring because in the unit test class I was using @WebMvcTest and it was only going to scan the Controller I’ve defined and the MVC infrastructure
