test classes mock getproperties

[Former Community Member]

I tried to mock getproperties in my test classes code details below.

main class:

public class SiteXMLCreator extends WCMUse implements Controller {

private static int level;
public int getLevel() {

        return level;
    }

    public void setLevel(int level) {
        this.level = level;
    }
public Page getSiteMap(Resource resource) throws Exception {
ResourceResolver resourceResolver = resource.getResourceResolver();
PageManager pm = resourceResolver.adaptTo(PageManager.class);
String path_to_page =getProperties().get("sectionparent", String.class);
Page parentProvided = pm.getPage(path_to_page);
int depth_selected = Integer.parseInt((String) getProperties().get("depth"));
.....
...//code ..
return parentProvided;
}

test class:

public class SiteXMLCreatorTest{
SiteXMLCreator underTest;
        @Mock
    Page page;
    @Mock
    PageManager pageManager;
    @Mock
    ValueMap properties;
    @Mock
    WCMUse WCMUSE_MOCK;
    FileInputStream is;
    @Mock
    ResourceResolver resourceResolver;
    @Mock
    String pagepath;
    @Mock
    String path_to_page;
    @Mock
    private Resource resource;
@Before
public void setUp() throws Exception {
underTest = new SiteXMLCreator();
}

@Test
public void testGetSiteMap() throws Exception {
when(WCMUSE_MOCK.getResource()).thenReturn(resource);
when(resource.getResourceResolver()).thenReturn(resourceResolver);
when(resourceResolver.adaptTo(PageManager.class)).thenReturn(pageManager);
when(WCMUSE_MOCK.getProperties().get("sectionparent", String.class)).thenReturn(path_to_page);// here we getting null pointer exception
when(pageManager.getPage(pagepath)).thenReturn(page);
underTest.getSiteMap(resource);
}
}

WCMUse class

public abstract class WCMUse
  implements Use
{
  private final Logger log = LoggerFactory.getLogger(WCMUse.class);
  private Bindings bindings;
  
  public void init(Bindings scriptBindings)
  {
    this.bindings = scriptBindings;
    try
    {
      activate();
    }
    catch (Exception e)
    {
      this.log.error("Failed to activate Use class", e);
    }
  }
  
  public abstract void activate()
    throws Exception;
  
  public <T> T get(String name, Class<T> type)
  {
    Object obj = this.bindings.get(name);
    try
    {
      return (T)type.cast(obj);
    }
    catch (ClassCastException e)
    {
      this.log.error("Failed to cast value", e);
    }
    return null;
  }
  
  public SightlyWCMMode getWcmMode()
  {
    return (SightlyWCMMode)get("wcmmode", SightlyWCMMode.class);
  }
  
  public PageManager getPageManager()
  {
    return (PageManager)get("pageManager", PageManager.class);
  }
  
  public Page getCurrentPage()
  {
    return (Page)get("currentPage", Page.class);
  }
  
  public Page getResourcePage()
  {
    return (Page)get("resourcePage", Page.class);
  }
  
  public ValueMap getPageProperties()
  {
    return (ValueMap)get("pageProperties", ValueMap.class);
  }
  
  public ValueMap getProperties()
  {
    return (ValueMap)get("properties", ValueMap.class);
  }
 
  
  public ValueMap getInheritedProperties()
  {
    return (ValueMap)get("inheritedPageProperties", ValueMap.class);
  }
  
  public Resource getResource()
  {
    return (Resource)get("resource", Resource.class);
  }
  
  public ResourceResolver getResourceResolver()
  {
    return getRequest().getResourceResolver();
  }
}

in test class we getting null pointer exception in   when(WCMUSE_MOCK.getProperties().get("sectionparent", String.class)).thenReturn(path_to_page);
