Import resource data from JSON file in classpath

Although it is possible to create a resource data hierarchy as text fixture manually using either Sling CRUD API or JCR API this can getting very tedious and affords a lot of boilerplate code. To make this easier a ContentLoader is provided which allows importing sample data stored as a JSON file in the classpath of the unit test and running the tests against this.

Example JSON data:

  "jcr:primaryType": "cq:Page",
  "jcr:content": {
    "jcr:primaryType": "cq:PageContent",
    "jcr:title": "English",
    "cq:template": "/apps/sample/templates/homepage",
    "sling:resourceType": "sample/components/homepage",
    "jcr:createdBy": "admin",
    "jcr:created": "Thu Aug 07 2014 16:32:59 GMT+0200",
    "par": {
      "jcr:primaryType": "nt:unstructured",
      "sling:resourceType": "foundation/components/parsys",
      "colctrl": {
        "jcr:primaryType": "nt:unstructured",
        "layout": "2;cq-colctrl-lt0",
        "sling:resourceType": "foundation/components/parsys/colctrl"

Example unit test:

public class ExampleTest {

  private final AemContext context = new AemContext();

  public void setUp() throws Exception {
    context.load().json("/sample-data.json", "/content/sample/en");

  public void testSomething() {
    Resource resource = context.resourceResolver().getResource("/content/sample/en");
    Page page = resource.adaptTo(Page.class);
    // further testing


This codes creates a new resource at /content/sample/en (and - if not existent - the parent resources) and imports the JSON data to this node. It can be accessed using the Sling Resource or JCR API afterwards.

Import binary data from file in classpath

It is also possible to import a binary file stored in the classpath beneath the unit tests using the ContentLoader. The data is stored usig a nt:file/nt:resource or nt:resource node type.

Example code to import a binary file:

context.load().binaryFile("/sample-file.gif", "/content/binary/sample-file.gif");

This codes creates a new resource at /content/binary/sample-file.gif (and - if not existent - the parent resources) and imports the binary data to a jcr:content subnode.

Building content

For easily building resources and pages a ContentBuilder provides convenience methods.


// create page
context.create().page("/content/sample/en", "/apps/sample/template/homepage");

// create resource
context.create().resource("/content/test1", ImmutableMap.<String, Object>builder()
        .put("prop1", "value1")
        .put("prop2", "value2")
