Could not yet find an adapter factory for the model class my_class from adaptable class org.apache.sling.testing.resourceresolver.MockResource

[rsGokulraj4]

Hi All,

I coudln't able to adapt the resource to my Sling Model class,
getting the error 
Could not yet find an adapter factory for the model class my_class from adaptable class org.apache.sling.testing.resourceresolver.MockResource.

Attaching the Sling models and junit files here.
Model Interface

package com.mycore.core.models;
import org.apache.commons.lang.StringUtils;
public interface ConfiguratorPromptModel {
    default String getNameplateId() {
        return StringUtils.EMPTY;
    }
}

Model Implementation

package com.mycore.core.internal.models.v1;

import com.mycore.core.models.ConfiguratorPromptModel;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.InjectionStrategy;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;

@Model(adaptables = Resource.class, adapters = {ConfiguratorPromptModel.class})
public class ConfiguratorPromptModelImpl  implements ConfiguratorPromptModel {
    public String getNameplateId() {
        return nameplateId;
    }
    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)
    private String nameplateId;

}

Test Case

package com.mycore.core.internal.models.v1;

import com.mycore.core.models.ConfiguratorPromptModel;
import io.wcm.testing.mock.aem.junit5.AemContext;
import io.wcm.testing.mock.aem.junit5.AemContextExtension;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.factory.ModelFactory;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

import static org.junit.jupiter.api.Assertions.assertEquals;

@ExtendWith(AemContextExtension.class)
class ConfiguratorPromptModelImplTest {
    private ConfiguratorPromptModel configuratorPromptModel;

    @BeforeEach
    public void setUp(AemContext context) throws Exception {
        context.load().json("/content/configuratorprompt/configuratorprompt.json", "/content/configuratorprompt.html");
        Resource resource = context.resourceResolver().getResource("/content/configuratorprompt.html");
        this.configuratorPromptModel = context.getService(ModelFactory.class).createModel(resource, ConfiguratorPromptModelImpl.class);
    }

    void getNameplateId() {
        assertEquals("nameplate", configuratorPromptModel.getNameplateId());
    }

}

Thanks,

Hi @rsGokulraj4 ,

PFB example 

@ExtendWith(AemContextExtension.class)
public class BannerTest {
    /** The Constant RESOURCE_CONTENT. */
    private static final String RESOURCE_CONTENT = "/core/models/banner/banner.json";

    /** The Constant TEST_CONTENT_ROOT. */
    private static final String TEST_CONTENT_ROOT = "/content/we-retail/us/en";

    /** The Constant RESOURCE. */
    private static final String RESOURCE = TEST_CONTENT_ROOT + "/jcr:content/root/container/container/banner";

    /** The model. */
    private Banner model;

    /** The resource. */
    private Resource resource;

    /**
     * Sets the up.
     *
     * @param aemContext the new up
     */
    @BeforeEach
    public void setup(AemContext aemContext) {
        Class<Banner> modelClass = Banner.class;
        aemContext.load().json(RESOURCE_CONTENT, TEST_CONTENT_ROOT);
        aemContext.addModelsForClasses(modelClass);
        resource = aemContext.currentResource(RESOURCE);
        model = resource.adaptTo(modelClass);
    }

    /**
     * Simple load and getter test.
     */
    @Test
    public void simpleLoadAndGetterTest() {
        assertEquals("1234", model.getId());
        assertEquals("Banner Text", model.getBannerText());
    }

}

Hope this helps

Thanks

Hi @Bimmi_Soi 
Thanks for the suggestion,
I tried the approach you have shared, but still getting the null exception on line.

 model = resource.adaptTo(modelClass); 

[Bimmi_Soi]

Check if you are using these imports and share the json file

import static org.junit.jupiter.api.Assertions.assertEquals;

import org.apache.sling.api.resource.Resource;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

import io.wcm.testing.mock.aem.junit5.AemContext;
import io.wcm.testing.mock.aem.junit5.AemContextExtension;

}

Is this working now?
