Description

According to the documentation, adding the following annotation to my graph class should allow me to opt-out from I/O-Tests, right?

@Graph.OptOut(test = "org.apache.tinkerpop.gremlin.structure.io.IoGraphTest", method = "*", reason = "IO Isuses on windows")

... well, unfortunately starting the test suite with this annotation creates the following exception (cancelling the execution of the suite as a whole):

Here's my full graph interface declaration, for reference:

@Graph.OptIn(Graph.OptIn.SUITE_STRUCTURE_STANDARD)
@Graph.OptOut(test = "org.apache.tinkerpop.gremlin.structure.io.IoGraphTest", method = "*", reason = "IO Isuses on windows")
@GraphFactoryClass(MyGraphFactoryImpl.class)
public interface MyGraph extends Graph {
 // ...
}

... and my test suite declaration:

@RunWith(StructureStandardSuite.class)
@GraphProviderClass(provider = MyGraphProvider.class, graph = MyGraph.class)
public class MyGraphStructureStandardTestSuite {

}
