+Additionally, you can specify attributes for the identity, perhaps custom items that were added with identity augmentation:

+[source,java]
+----
+@Inject
+SecurityIdentity identity;
+
+@Test
+@TestSecurity(user = "testUser", "roles = {"admin, "user"}, attributes = {
+            @SecurityAttribute(key = "answer", value = "42", type = AttributeType.LONG) }
+void someTestMethod() {
+    Long answer = identity.<Long>getAttribute("answer");
+...
+}
+----
+
+This will run the test with an identity with an attribute of type `Long` named `answer`.
