I’m trying to write a unit test for one of my services that does a query as part of the service. As such, I need a JCR_OAK AemContext to be able to test these changes. My unit test roughly looks like below:

@ExtendWith(AemContextExtension.class)
class MyUnitTest {
    private static final String PATH = "/content/we-retail/language-masters/en";
    // need an OAK context to be able to do queries
    final AemContext CTX = new AemContext(ResourceResolverType.JCR_OAK);

    @BeforeEach
    public void init() {
        CTX.load().json("/some/file.json", PATH);
    }

    
    void my_test() {
        // do something using context
    }
}

I generated my project from the AEM Archetype version 27. Additionally, I added the following dependency in my core POM to support JCR_OAK contexts.

<dependency>
                <groupId>org.apache.sling</groupId>
                <artifactId>org.apache.sling.testing.sling-mock-oak</artifactId>
                <version>2.1.6</version>
                <scope>test</scope>
</dependency>

However, when trying to run my unit tests, I get the following errors in the log:

[main] INFO org.apache.sling.jcr.resource.internal.helper.jcr.JcrResourceProvider - Detected Oak based repository. Using improved JCR Resource Listener with observation queue length 1000

Did I miss a dependency or is something wrong in my set-up? I did find this related ticket although I don’t see how that fits into this issue.

Any pointers could help, so thanks in advance!

Hi @koenve,

Can you try to use ResourceResolverType.JCR_MOCK instead of JCR_OAK if you are not using/testing advanced features like JCR eventing or Versioning related APIs.

koenve · 4/7/21

Unfortunately, as we're using a JCR Query (via Session), we need a JCR_OAK AemContext.
