20 Spring Security testing

This chapter covers

Testing integration with Spring Security configurations for endpoints
Defining mock users for tests
Testing integration with Spring Security for method-level security
Testing reactive Spring implementations

The legend says that writing unit and integration tests started with a short verse:

“99 little bugs in the code,

99 little bugs.

Track one down, patch it around,

There’s 113 little bugs in the code.”

With time, software became more complex, and teams became larger. Knowing all the functionalities implemented over time by others became impossible. Developers needed a way to make sure they didn’t break existing functionalities while correcting bugs or implementing new features. ...
