Running Tinkerpop test in Janusgraph repo

Hi I'm trying to run the below Tinkerpop test to test out some of the changes I've made to Janusgraph. By copying the test over from Tinkerpop repo into Janusgraph repo (just for testing one test).

@RunWith(Parameterized.class)
public class TraversalInterruptionTest extends AbstractGremlinProcessTest {
    private static final Logger logger = LoggerFactory.getLogger(TraversalInterruptionTest.class);

    @Parameterized.Parameters(name = "expectInterruption({0})")
    public static Iterable<Object[]> data() {
        return Arrays.asList(new Object[][]{
                // ...
        });
    }

    @Parameterized.Parameter(value = 0)
    public String name;

    @Parameterized.Parameter(value = 1)
    public Function<GraphTraversalSource,GraphTraversal<?,?>> traversalBeforePause;

    @Parameterized.Parameter(value = 2)
    public UnaryOperator<GraphTraversal<?,?>> traversalAfterPause;

    @Test
    @LoadGraphWith(GRATEFUL)
    public void shouldRespectThreadInterruptionInVertexStep() throws Exception {
        // ...
    }
}

@RunWith(Parameterized.class)
public class TraversalInterruptionTest extends AbstractGremlinProcessTest {
    private static final Logger logger = LoggerFactory.getLogger(TraversalInterruptionTest.class);

    @Parameterized.Parameters(name = "expectInterruption({0})")
    public static Iterable<Object[]> data() {
        return Arrays.asList(new Object[][]{
                // ...
        });
    }

    @Parameterized.Parameter(value = 0)
    public String name;

    @Parameterized.Parameter(value = 1)
    public Function<GraphTraversalSource,GraphTraversal<?,?>> traversalBeforePause;

    @Parameterized.Parameter(value = 2)
    public UnaryOperator<GraphTraversal<?,?>> traversalAfterPause;

    @Test
    @LoadGraphWith(GRATEFUL)
    public void shouldRespectThreadInterruptionInVertexStep() throws Exception {
        // ...
    }
}

But I'm getting

java.lang.NullPointerException: Cannot invoke "org.apache.tinkerpop.gremlin.GraphProvider.getStaticFeatures()" because "this.innerGraphProvider" is null

java.lang.NullPointerException: Cannot invoke "org.apache.tinkerpop.gremlin.GraphProvider.getStaticFeatures()" because "this.innerGraphProvider" is null

I need to be able to inject the graph implementation into this test somehow? How can I do that? Thank you.

Solution:

You should copy the test suite definition test

This workflow was suggested by @Boxuan Li btw. So would be great if you already know the answer 😄

Oh nope you don't need to copy this test

Search in the TinkerPop repository, there should be a mention of TraversalInterruptionTest .class

I've got this now

java.lang.Exception: The ProcessStandardSuite will not run for this Graph until it is publicly acknowledged with the @OptIn annotation on the Graph instance itself

Oh I've got it

Sorry let me rephrase my words. Let's say you want to debug TraversalInterruptionTest in JanusGraph. 1. Open JanusGraph repo in your IDE. 2. Find BerkeleyJanusGraphProcessTest - see how it mentions ProcessStandardSuite 3. Open ProcessStandardSuite (either from TinkerPop repo or from your current IDE window directly) 4. Copy it to JanusGraph repo 5. Remove other tests other than TraversalInterruptionTest

Thanks for this, I was able to run the test successfully 💪
