AssertJ for Sling

Implemented to speed up testing of Sling applications.

Usage

1. Asserting Resource Properties:

Assert that the resource has the specified resource type.

hasResourceType(String expectedResourceType)

assertThat(resource)
    .hasResourceType("sling:Folder");

Assert that the resource has the specified resource super type.

hasResourceSuperType(String expectedSuperType)

assertThat(resource)
   .hasResourceSuperType("sling:Folder");

Assert that the resource has the specified resource path.

hasResourcePath(String expectedPath)

assertThat(resource)
    .hasResourcePath("/content/sling/en");

Assert that the resource has the specified name.

hasResourceName(String expectedName)

assertThat(resource)
    .hasResourceName("jcr:content"); 

2. Child Resource Assertions:

Assert that the resource has children.

hasChildren()

    assertThat(resource)
        .hasChildren();

Assert that the resource has a specific child resource.

hasChildResource(String childResourcePath)

assertThat(resource)
    .hasChildResource("jcr:content");           

Asserts properties or conditions on a child resource.

childResourceSatisfies(String childResourcePath, Consumer<Resource> assertion)

assertThat(resource)
    .childResourceSatisfies(
        "jcr:content", 
        content -> assertThat(content).hasProperty("jcr:title"));    

3. Resource Property Assertions:

Assert that the resource has a specific property.

hasProperty(String propertyName)

assertThat(resource)
    .hasProperty("jcr:title");

4. Resource Value Assertions (for ValueMap):

Assert that a property in the resource's ValueMap has a specific value.

hasPropertyValue(String propertyName, Object expectedValue)

assertThat(resource)
    .hasPropertyValue("jcr:title", "Sling");

Assert that a property in the ValueMap matches a given predicate.

propertyValueSatisfies(String propertyName, Class<PT> clazz, Consumer<PT> assertion)

assertThat(resource)
    .propertyValueSatisfies(
        "jcr:title", 
        String.class, 
        title -> assertThat(title).isEqualTo("Title"));

Extracting property values

extracting(Object... keys)

assertThat(resource)
    .extracting("jcr:title", "jcr:description")
    .containsExactly("Title", "Description");

5. Resource Adaptation Assertions:

Assert that the resource can be adapted to a specific type.

canAdaptTo(Class<T> type)

assertThat(resource)
    .canAdaptTo(TitleModel.class);    

6. Resource Existence Assertions:

Assert that the resource exists.

exists()

assertThat(resource)
    .exists();
