Is it possible to has more than 1 @WithMockUser in one test method?

Question

I am using Spring boot + Spring Security + Junit 5, latest version.

Is it possible that in one testing method, I can use two @WithMockUser() ? So the testing method run two times and each time with different @WithMockUser information? For example, I have

@WithMockUser(username="admin",roles={"USER","ADMIN"})
@WithMockUser(username="user" ,roles={"USER","ADMIN"})
public void test1() {}

Equals run two times. like:

@WithMockUser(username="admin",roles={"USER","ADMIN"})
public void test1() {}

and

@WithMockUser(username="user" ,roles={"USER","ADMIN"})
public void test1() {}

You can use UserRequestPostProcessor to configure MockMvc request to achieve the equivalent behaviour of @WithMockUser.

Together with Junit5 's parameterised test , you can do something like :

import static org.springframework.security.test.web.servlet.request.SecurityMockMvcRequestPostProcessors.user;
import static org.junit.jupiter.params.provider.Arguments.of;


@ParameterizedTest
@MethodSource("withMockUser")
void someTest(String username, String[] roles) throws Exception {

    mockMvc.perform(get("/foo")         
           .with(user(username).roles(roles)))
           .......
}

private static Stream<Arguments> withMockUser() {
    return Stream.of(
            of("admin", new String[]{"USER", "ADMIN"}),
            of("user", new String[]{"USER", "ADMIN"})
    );
}
