JSF Bean testing using JoinFaces and SpringBoot

This is a simple demo to demonstrate how to test a jsf scoped bean in Spring Boot context using JoinsFaces.

This code is inspired by some commercial project commits of @DEXRAY and updated by @larmic and @renepa

Usage

Dependency is available in maven central repository. Just add to your pom.xml

<dependency>
   <groupId>de.larmic</groupId>
   <artifactId>joinfaces-bean-test</artifactId>
   <version>1.0</version>
   <scope>test</scope>
</dependency>

Compatibility list

Version	Spring Boot	JoinFaces
<= 0.3	1.5.x	2.3.x
0.4	2.0.x	3.0.0.RC1
0.6	2.0.x	3.0.x
0.7	2.0.x	3.1.x
>= 0.8	2.0.x	3.2.x
1.0	2.1.x	4.x.x

Example

@Named
@RequestScoped
public class ContractsBean {

    private String customerNumber;

    @PostConstruct
    public void init() {
        customerNumber = FacesContext.getCurrentInstance()
                .getExternalContext()
                .getRequestParameterMap()
                .get("customerNumber");

    }

    public String getCustomerNumber() {
        return customerNumber;
    }
}

This simple bean reads url query parameter customerNumber. Using JoinFaces and SpringBoot this bean is not testable by default injection into a test class.

This demo allows following integration test:

@RunWith(SpringRunner.class)
@ContextConfiguration(initializers = {FacesContextMockApplicationContextInitializer.class})
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)
public class ContractsBeanTest {
    
    @Autowired
    private ApplicationContext context;

    @Test
    public void testCreateRequestScopedBeanWithCustomerNumberIsSet() {
        final ContractsBean bean = new JsfSpringBeanBuilder(context)
                .withExternalParameter("customerNumber", "unit-test-customer-number")
                .build(ContractsBean.class);

        assertThat(bean.getCustomerNumber()).isEqualTo("unit-test-customer-number");
    }

    @Test
    public void testCreateRequestScopedBeanWithCustomerNumberIsNull() {
        final ContractsBean bean = new JsfSpringBeanBuilder(context)
                .build(ContractsBean.class);

        assertThat(bean.getCustomerNumber()).isNull();
    }
}
