java.lang.IllegalArgumentException: Failed to evaluate expression 'USER'

Hi all,

I am creating Spring JUnit testing. My service method is

    @PreAuthorize("USER")
    public void someMethod();

and my test method is

    @Test
    @WithMockUser(roles={"USER"})
    public void testMethod() {
        service.someMethod();
    }

I am getting run time exception as follows

java.lang.IllegalArgumentException: Failed to evaluate expression 'USER'

Do not use expression with @PreAuthorize. Change your code using hasRole()

Working Thanks.
