This PR adds the integration test of the TeamController class.

Don't we need to use @RunWith(SpringRunner.class)? I checked it works without using it. But as far as I remember I had to put it or else spring would not recognize the annotations.

@arpan-banerjee7 I think this is necessary when using Junit 4, as far as the documentation is concerned:

When using JUnit 4, this annotation should be used in combination with @RunWith(SpringRunner.class).

https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/test/autoconfigure/web/servlet/WebMvcTest.html

Since the test is written in Junit 5, it should be fine I guess.
