When I run the following Junit testing code:

import com.adobe.aemfd.docmanager.Document;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.w3c.dom.Element;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;

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

class TableOfContentTest {

    private Document pdfDoc;
    private ProcessInputXML processInputXML;
    private TableOfContent tableOfContent;

    @BeforeEach
    void setUp() throws Exception {
        // Load valid PDF content from a file or resource
        InputStream pdfInputStream = getClass().getResourceAsStream("/logo.pdf"); // Ensure this file exists in resources
        pdfDoc = new Document(pdfInputStream);

        // Initialize the ProcessInputXML object
        org.w3c.dom.Document inputXML = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
        processInputXML = new ProcessInputXML(inputXML);

        // Create the TableOfContent instance
        tableOfContent = new TableOfContent(pdfDoc, processInputXML);
    }
    @Test
    void shouldThrowAnExceptionOrHandleErrorsForANullTocMap()  {

        // Use the initialized tableOfContent instance
        assertNotNull(tableOfContent);
    }
}

The error message, java.lang.NoClassDefFoundError: com/adobe/aemfd/docmanager/source/DocumentSourceHandler, occurred at line 24 (

InputStream pdfInputStream = getClass().getResourceAsStream("/logo.pdf");

) and25 (

pdfDoc = new Document(pdfInputStream);

). How can I find out the best resolution, particularly initialization, to avoid java.lang.NoClassDefFoundError: com/adobe/aemfd/docmanager/source/DocumentSourceHandler? Thanks for your help. By the way, when I look for com.adobe.aemfd.docmanager in the import side, I cannot find out source.DocumentSourceHandler. What version of dependency in Maven repository can include com.adobe.aemfd.docmanager.source.DocumentSourceHandler? If so, that's great. Otherwise, what's the best alternative way to be worked out that problem?

Hi @yeouluen0929

This is already discussed here

Or

you can avoid this by using the org.mockito.Mockito.mockConstruction to simulate the behavior of Document, ProcessInputXML, and TableOfContent

This approach avoids initializing the actual Document object and its dependencies, which may not be available outside the AEM runtime

Thanks

Thanks @Vijendra1. Could you also please provide me the codes that can avoid this by using the org.mockito.Mockito.mockConstruction to simulate the behavior of Document, ProcessInputXML, and TableOfContent and approach avoids initializing the actual Document object and its dependencies, which may not be available outside the AEM runtime? Thanks.
