Hi everyone, I was rewriting some JUnit tests to Kotest and stumbled upon the @WithMockUser annotation. I found this old issue: https://github.com/kotest/kotest/issues/337
The solution mentioned there works but in my opinion, it's pretty ugly. Comparing:

@WithMockUser(authorities = [EDIT_SCHEDULED_CAMPAIGNS])
        fun `should handle errors`() {

with

it("should handle errors") {
            SecurityContextHolder.getContext().authentication =
                PreAuthenticatedAuthenticationToken(null, null, listOf(SimpleGrantedAuthority(EDIT_SCHEDULED_CAMPAIGNS)))

Any opinion @Emil Kantis or @Alex Kuznetsov maybe?

Normally we would use an extension for injecting behavior. I think it would be possible to do it like this as well:

describe("ErrorHandling") {
   extensions(SpringMockUserExtension(EDIT_SOMETHING))
 
   it("should handle errors") {
       // ...
   }
   
   // any other siblings would also have the mock user injected
}

I think you could define it as a TestCaseExtension

Thanks for the clarification. I'll create a PR when I have some time 👍
