How to load a json in a MockJcr inside a unit test?

Question

How could you load a json with test data into a MockJcr inside a Java Unit test? 
 
I know it is possible to load a mock json into an AemContext, e,g,

@ExtendWith(AemContextExtension.class)
@ExtendWith(MockitoExtension.class)
class MyTest {

final AemContext context = new AemContext();

@Mock
    private Session session;

private final String PROPERTY = "myproperty";

private final String[] ARGS={"myvalue"};

@BeforeEach
    void setup() {
        context.registerAdapter(WorkflowSession.class, Session.class, session);
        context.load().json("/pages/MyPage.json", "/content/page");
    }

public void myWorkflowViaSling() throws WorkflowException {
        String[] values = context.resourceResolver().getResource("/content/page/jcr:content").getValueMap().get(PROPERTY, ARG);
        assertEquals(ARGS,values);
    }
}

But is there a way to load a mock json into a MockJcr?

class MyWorkflowTest {
    
    private final String PROPERTY = "myproperty";

private final String ARGS={"myvalue"};
    
    public void myWorkflowViaJCR() throws Exception {
        Session mockSession = MockJcr.newSession();

// Here, I am adding nodes 1 by 1 and setting their properties, where it would be simpler to load a json
        mockSession.getRootNode().addNode("jcr:content").setProperty(PROPERTY, ARGS);

Value[] valueMap = mockSession.getNode("/" + "jcr:content").getProperty(PROPERTY).getValues();
        assertEquals(ARGS[0],valueMap[0].getString());
    }
}

I found a working solution to load JSON data into a mock JCR.

@ExtendWith(AemContextExtension.class)
@ExtendWith(MockitoExtension.class)
class MyTest {

    private final AemContext jcrContext = new AemContext(ResourceResolverType.JCR_MOCK);

    private final Session jcrSession = jcrContext.resourceResolver().adaptTo(Session.class);
    
    private final String PROPERTY = "myproperty";

    private final String ARGS={"myvalue"};
    
    @2785667
    public void myTestViaJCR() throws Exception {
        assertNotNull(jcrSession);

        jcrContext.registerAdapter(WorkflowSession.class, Session.class, jcrSession);
        jcrContext.load().json("/pages/MyPage.json", "/content/page");

        Node root = jcrSession.getRootNode();
        Node newNode = root.addNode("content").addNode("page").addNode("jcr:content");
        newNode.setProperty(PROPERTY, ARGS);
        jcrSession.save();

        Node node = jcrSession.getNode("/" + "content" + "/" + "page" + "/" + "jcr:content");
        assertNotNull(node);

        Property property = node.getProperty(PROPERTY);
        assertNotNull(property);

        Value[] valueMap = property.getValues();
        assertNotNull(valueMap);

        assertEquals(ARGS[0],valueMap[0].getString());
    }
}

Hi @jeremylanssiers - check this, if it helps@Rule    public final AemContext context = new AemContext();    @Test    public void testLoadJsonFile() throws RepositoryException, JSONException {        // Add test node to Mock JCR        Session session = context.resourceResolver().adaptTo(Session.class);        Node node = session.getRootNode().addNode("content/myresource", "nt:unstructured");        node.setProperty("myproperty", "myvalue");        session.save();                InputStream is = getClass().getResourceAsStream("/mytest.json");        JSONObject jsonObject = new JSONObject(new JSONTokener(is));        context.load().json(jsonObject, "/content/myresource");        Node testNode = session.getNode("/content/myresource");        assertNotNull(testNode);    }}
