Hippo and unit testing

[satija...@gmail.com]

Hi,

Currently working on junit test cases, I am looking for hippo test suite or testing framework for hippo, mainly to test HST components for now.

i went through below links :

https://www.bloomreach.com/en/resources/blogs/2010/10/Unit+testing+your+HST2+components+with+EasyMock.html

https://iprofs.wordpress.com/2010/10/19/hst-and-mockito-sitting-on-a-tree/

These are implemented with mockito and easy mock with the same example test case on  getContentBean method

and i get no particular result, if i want to use internal methods of hippo test suite ( i downloaded the project from https://code.onehippo.org/cms-community/hippo-testsuite) to test HST components.

I have a little different scenario :

here is my component class :

package org.example.components;

import org.example.components.info.DocumentIncludeInfo;

import org.hippoecm.hst.content.beans.standard.HippoDocument;

import org.hippoecm.hst.core.component.HstComponentException;

import org.hippoecm.hst.core.component.HstRequest;

import org.hippoecm.hst.core.component.HstResponse;

import org.hippoecm.hst.core.parameters.ParametersInfo;

import org.onehippo.cms7.essentials.components.CommonComponent;

import org.onehippo.cms7.essentials.components.info.EssentialsDocumentComponentInfo;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

@ParametersInfo(type = DocumentIncludeInfo .class)

public class HeaderComponent extends CommonComponent {

public static final Logger log = LoggerFactory.getLogger(HeaderComponent.class);

       

    

    public void doBeforeRender(final HstRequest request, final HstResponse response) throws HstComponentException {

        super.doBeforeRender(request, response);

        final DocumentIncludeInfo paramInfo = getComponentParametersInfo(request);

        final HippoDocument document = getDocumentItem(paramInfo);

        request.setAttribute("document", document);            

    }

    public HippoDocument getDocumentItem(final DocumentIncludeInfo componentInfo) {

        return getHippoBeanForPath(componentInfo.getDocPath(), HippoDocument.class);

}

}

(where commoncomponent extends existing basehstcomponent class of hippo )

here is my test class for this component with easy mock :

package org.example.junit;

import org.hippoecm.hst.component.support.bean.BaseHstComponent;

import org.hippoecm.hst.content.beans.standard.HippoBean;

import org.hippoecm.hst.content.beans.standard.HippoDocument;

import org.hippoecm.hst.core.component.HstRequest;

import org.junit.Before;

import org.junit.Test;

import org.hippoecm.hst.mock.core.component.MockHstRequest;

import org.hippoecm.hst.mock.core.component.MockHstResponse;

import org.hippoecm.hst.site.HstServices;

import static org.easymock.classextension.EasyMock.*;

import static org.junit.Assert.*;

import org.example.components.HeaderComponent;

/**

* Test for {@link com.jeroenreijn.site.components.AbstractBaseHstComponent}

 * @param <AbstractBaseHstComponent>

*/

public class ComponentTest<AbstractBaseHstComponent> {

MockHstRequest fakeRequest;

MockHstResponse fakeResponse;

BaseHstComponent component;

HeaderComponent component1;

HstServices component2;

@Before

public void setUp() throws Exception {

fakeRequest = new MockHstRequest();

fakeResponse = new MockHstResponse();

component2 = createMockBuilder(HstServices.class).addMockedMethod("getComponentManager").createMock();

component = createMockBuilder(BaseHstComponent.class).

addMockedMethod("getComponentParametersInfo", HstRequest.class).

createMock();

component1= new HeaderComponent();

}

@Test

public void testDocumentOnRequestAfterDoBeforeRender() throws Exception {

HippoBean bean = new HippoDocument();

//record the expected behavior

expect(component.getComponentParametersInfo(fakeRequest)).andReturn(bean);

//stop recording and switch the mocked Object to replay state.

//replay(component);

component1.doBeforeRender(fakeRequest,fakeResponse);

//verify the specified behavior has been used

//verify(component);

assertSame(fakeRequest.getAttribute("document"),bean);

}

}

here is my test class with mockito ;

package org.example.junit;

import org.hippoecm.hst.component.support.bean.BaseHstComponent;

import org.hippoecm.hst.content.beans.standard.HippoDocument;

import org.hippoecm.hst.core.component.HstRequest;

import org.hippoecm.hst.core.component.HstResponse;

import org.hippoecm.hst.core.container.ComponentManager;

import org.hippoecm.hst.site.HstServices;

import org.junit.Before;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.mockito.Mock;

import org.mockito.Spy;

import org.mockito.runners.MockitoJUnitRunner;

import org.onehippo.cms7.essentials.components.CommonComponent;

import static org.mockito.Mockito.*;

import org.example.components.HeaderComponent;

import org.example.components.info.DocumentIncludeInfo;

/**

 * Test for {@link com.jeroenreijn.site.components.AbstractBaseHstComponent}

 */

@RunWith(MockitoJUnitRunner.class)

public class AbstractBaseHstComponentTest {

  @Mock public HstRequest request;

  @Mock public DocumentIncludeInfo info;

  @Mock public HstResponse response;

  @Mock public CommonComponent component ;

@Spy HeaderComponent component1= null;

  @Before

  public void setUP(){

 component1 = new HeaderComponent();

// HstServices.setComponentManager(compManager) ; 

  }

  

  

  

  @Test

  public void testDocumentOnRequestAfterDoBeforeRender() throws Exception {

    //stub

 

    doReturn("/content/documents/myhippoproject/headernew").when(info).getDocPath();

    //test

    

    component1.doBeforeRender(request, response);

    //verify

    //verify(request).setAttribute(anyString(), any(HippoDocument.class));

  }

}

In both easymock and mockito test cases, I am getting nullpointer exception when i create object for headercomponent class

Error :

File : org.onehippo.cms7.essentials.components.CommonComponent

line no. 93 : doBeforeRenderExtension = HstServices.getComponentManager().getComponent(DoBeforeRenderExtension.class.getName());

where getComponentManager() returns null.

Therefore i tried to create objects of basehstcomponent class ( as headercomponent class extends commoncomponent class and commoncomponent class extends basehstcomponent) , and hstservice class so that something can help with mocking componentmanager.

But nothing helped. here below are the errors :

java.lang.NullPointerException

Please help !!

If you want your unit test to test nothing else but your java class (i.e. don't pull in more logic, up to a fully bootstrapped repository),

you may need to resort to using PowerMock to be able to mock static methods (such as HstServices#getComponentManager).

Here is an example of how to use PowerMock.

cheers

Hi,

I tried with easymock and it works when we try to just hippobean from request and see this bean is put as an attribute in request.

package org.example.components;

import org.hippoecm.hst.content.beans.standard.HippoBean;
import org.hippoecm.hst.content.beans.standard.HippoDocument;
import org.hippoecm.hst.core.component.HstRequest;

import org.hippoecm.hst.core.container.HstContainerURL;
import org.hippoecm.hst.core.container.HstContainerURLImpl;
import org.hippoecm.hst.core.request.HstRequestContext;
import org.junit.Before;
import org.junit.Test;
import org.hippoecm.hst.mock.content.beans.standard.MockHippoBean;
import org.hippoecm.hst.mock.core.component.MockHstRequest;
import org.hippoecm.hst.mock.core.component.MockHstResponse;

import static org.easymock.classextension.EasyMock.*;
import static org.junit.Assert.*;

import org.example.components.SimpleComponent;
import org.hippoecm.hst.container.ModifiableRequestContextProvider;
import org.hippoecm.hst.mock.core.request.MockHstRequestContext;

/**
 * Test for {@link com.jeroenreijn.site.components.AbstractBaseHstComponent}
 */

public class SimpleComponentTest {

    MockHstRequest fakeRequest;
    MockHstResponse fakeResponse;
    SimpleComponent component;

    @SuppressWarnings({ "deprecation", "null" })

    @Before
    public void setUp() throws Exception {
        fakeRequest = new MockHstRequest();
        fakeResponse = new MockHstResponse();

        MockHstRequestContext requestContext = new MockHstRequestContext();
        MockHippoBean mockedBean = new MockHippoBean();
        HstContainerURLImpl baseURL = new HstContainerURLImpl();
        baseURL.setContextPath("/site");
        baseURL.setPathInfo("/hello");
        baseURL.setRequestPath("/hello");
        baseURL.setHostName("localhost:7080");
        baseURL.setPortNumber(7080);
        ModifiableRequestContextProvider.set(requestContext);
       
        requestContext.setBaseURL(baseURL);
        // Retrieve the document based on the URL
        requestContext.setContentBean(mockedBean);
  
       
        component = createMockBuilder(SimpleComponent.class).
                addMockedMethod("getContentBean", HstRequest.class). createMock();

    }

    @Test
    public void testDocumentOnRequestAfterDoBeforeRender() throws Exception {

        HippoBean bean = new HippoDocument();

        //record the expected behavior

        expect(component.getContentBean(fakeRequest)).andReturn(bean);

        //stop recording and switch the mocked Object to replay state.

        replay(component);

        component.doBeforeRender(fakeRequest,fakeResponse);

        //verify the specified behavior has been used

        verify(component);

        assertSame(fakeRequest.getAttribute("document"),bean);
    }
}

Now, If I try to fetch the bean that is created using current request URI (accessing page), it still give null pointer. Have created Mockrequest and Mockbean as well. Any pointers here will help.

[neha malhotra]

In Simplecomponent class, if we have

HippoBean bean = getContentBean(request);
        if(bean!=null) {
            request.setAttribute("document",bean);
        }
 
this works.

But when I put

CustomBean document = (CustomBean ) ctx.getContentBean();

it gives NPE.

What is ctx? Where do you get that from? you need to create a request context. There is a MockHstRequestContext, which you can use, but you need some component to be able to get it. This you can do with ModifiableRequestContextProvider.set().
