How to use RestAssured with Spring Security - spring

Question

I am using Spring 4 with Spring Security 3.2. The application is running perfectly so far. Now I am writing Test Cases for all the REST services using MockMVC and RestAssured.
I have a simple Controller
#RestController
#RequestMapping("/secure")
public class MyController{
#RequestMapping(method = RequestMethod.GET)
public String getAllMedia(){
return "SECURE TEST COMPLETE";
}
}
And I have a spring-rest-servlet.xml file which has <mvc:annotation-driven />
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<mvc:annotation-driven />
<context:component-scan base-package="com.mp.web.controller.common" />
</beans>
And spring-security-context.xml looks like this
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<security:http create-session="stateless"
entry-point-ref="authenticationEntryPoint"
authentication-manager-ref="authenticationManager">
<security:custom-filter ref="customRestFilter"
position="BASIC_AUTH_FILTER" />
<security:intercept-url pattern="/api/p/**" access="ROLE_USER" />
<security:intercept-url pattern="/api/login**"
access="IS_AUTHENTICATED_ANONYMOUSLY" requires-channel="https" />
</security:http>
<bean id="authenticationEntryPoint"
class="com.mp.web.security.CustomAuthenticationEntryPoint" />
<bean id="customRestFilter"
class="com.mp.web.security.filter.AuthenticationTokenProcessingFilter">
<constructor-arg name="authenticationManager"
ref="authenticationManager" />
</bean>
<security:authentication-manager alias="authenticationManager">
<security:authentication-provider ref="restAuthenticationProvider" />
</security:authentication-manager>
<bean id="restAuthenticationProvider"
class="com.mp.web.security.auth.RestAuthenticationProvider" />
</beans>
The application is just working as expected but whey I run the test case the spring security filter does not execute 'customRestFilter'
Here is my Test Class
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration({"classpath:application-context.xml",
"classpath:spring-rest-servlet.xml",
"classpath:spring-security-context.xml"})
public class Test {
#Autowired
private FilterChainProxy springSecurityFilterChain;
#Autowired
private WebApplicationContext webApplicationContext;
#Autowired
MyController myController;
#Before
public void init(){
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
.addFilter(springSecurityFilterChain).build();
}
#Test
public void test1() throws Exception {
given().mockMvc(mockMvc).standaloneSetup(myController)
.header("Authorization", userHeaderToken) // Token for user
.when().get("/secure")
.then().log().body();
}
}
The userHeaderToken is used to identify which from which user I got the request from and its all handled in 'customRestFilter'. But my requests from Test case never come to the filter.
Can some one guide me how to get the request pass through that filter.
Thanks.
