AEM Cloud Service - Sample JUnit Test using AEMContext

Goal

Create a simple JUnit for testing a Sling Model class. Unit test checks if the model class function returns content in JCR as-is...

Test Failure

Solution

1) Create Sling Model apps.experienceaem.assets.core.models.FreeFormModel

package apps.experienceaem.assets.core.models;

import com.adobe.cq.export.json.ExporterConstants;
import org.apache.commons.lang3.StringUtils;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Default;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Exporter;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;

@Model( adaptables = Resource.class,
        defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
@Exporter(name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
        extensions = ExporterConstants.SLING_MODEL_EXTENSION)
public class FreeFormModel {
    @ValueMapValue
    @Default(values = StringUtils.EMPTY)
    private String content;

    public String getContent() {
        return content;
    }
}

2) Add the mock JCR content in eaem-mock-test\core\src\test\resources\com\eaem\assets\models\FreeFormModelTest.json

{
  "eaem": {
    "free-form": {
      "jcr:primaryType": "nt:unstructured",
      "jcr:createdBy": "admin",
      "jcr:lastModifiedBy": "admin",
      "jcr:created": "Wed Apr 13 2022 12:55:28 GMT-0400",
      "content": "<p>DOEST NOT MATCH Experience AEM</p>\r\n",
      "jcr:lastModified": "Wed Apr 13 2022 12:56:28 GMT-0400"
    }
  }
}

3) Add the test case apps.experienceaem.assets.core.models.FreeFormModelTest

package apps.experienceaem.assets.core.models;

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.testing.mock.sling.ResourceResolverType;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.extension.ExtendWith;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;

import java.util.Objects;

@ExtendWith(AemContextExtension.class)
public class FreeFormModelTest {
    private static final String FF_CONTENT_PATH = "/content/eaem/free-form";
    private static final String JSON_FILE_PATH = "/com/eaem/assets/models/FreeFormModelTest.json";
    private static final String EXPECTED_CONTENT = "<p>Experience AEM</p>\r\n";

    private AemContext aemContext = new AemContext(ResourceResolverType.RESOURCERESOLVER_MOCK);
    private FreeFormModel ffModel;

    @BeforeEach
    void setUp() throws Exception {
        aemContext.addModelsForClasses(FreeFormModel.class);
        aemContext.load().json(JSON_FILE_PATH, "/content");
        Resource resource = aemContext.currentResource(FF_CONTENT_PATH);
        ffModel = Objects.requireNonNull(resource.adaptTo(FreeFormModel.class));
    }

    @Test
    void testGetContent() {
        assertEquals(EXPECTED_CONTENT, Objects.requireNonNull(ffModel).getContent());
    }
}
