I’m running a test on Facescontext.getCurrentInstance() is returning null.

Ambience:

Spring 4.3
JSF 2.2
Scope view
Escope view is customized for Spring

This is scope class, it works

public class MyClass implements Scope{

public static final String VIEW_SCOPE_CALLBACKS = "viewScope.callbacks";

public synchronized Object get(String name, ObjectFactory<?> objectFactory){
    Object instance = this.getViewMap().get(name);
    if (instance == null){
        instance = objectFactory.getObject();
        this.getViewMap().put(name, instance);
    }
    return instance;
}


public Object remove(String name){
    Object instance = getViewMap().remove(name);
    if (instance != null){
        Map<String, Runnable> callbacks = (Map<String, Runnable>) getViewMap().
        get(VIEW_SCOPE_CALLBACKS);
        if (callbacks != null){
            callbacks.remove(name);
        }
    }
    return instance;
}


public void registerDestructionCallback(String name, Runnable runnable)
{
    Map<String, Runnable> callbacks = (Map<String, Runnable>) getViewMap().
    get(VIEW_SCOPE_CALLBACKS);
    if (callbacks != null){
        callbacks.put(name, runnable);
    }
}

public Object resolveContextualObject(String name){
    FacesContext facesContext = FacesContext.getCurrentInstance();
    FacesRequestAttributes facesRequestAttributes = new FacesRequestAttributes(facesContext);
    return facesRequestAttributes.resolveReference(name);
}

public String getConversationId(){
    FacesContext facesContext = FacesContext.getCurrentInstance();
    FacesRequestAttributes facesRequestAttributes = new FacesRequestAttributes(facesContext);
    return facesRequestAttributes.getSessionId() + "-" + facesContext.getViewRoot().getViewId();
}

private Map<String, Object> getViewMap(){
    return FacesContext.getCurrentInstance().getViewRoot().getViewMap();
}

}

getViewMap this is the error method

So this is the mapping to Spring in the . xml file

<bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
<property name="scopes">
    <map>
        <entry key="view">
            <bean class="com.sys.util.SysViewScope" />
        </entry>
    </map>
</property>

So this is the injection of the object view, no test


    @Autowired
    @Qualifier("clientCapture")
    private SysClientCaptureController      clientCaptureController;

Error causing when running the test

Tips where I should act to configure the test and when I get there in that part of the context no longer generates Nullpointerexception?

Post the full stacktrace.
