java.lang.IllegalStateException: Missing the '-javaagent' JVM argument. Make sure you run the tests with the Quasar java agent attached to your JVM

Question

When trying to run test for CORDA the given Test case getting the following error. I am using JDK 1.8., Intellij IDEA on Windows 10. Even Though I have mentioned the the Quasar.jar in VM options.

RUN >> Edit Configurations >> Junit>> Required Test Class >>VM options:-ea -javaagent:lib\quasar.jar enter image description here

    )));

    private final StartedMockNode Mint = network.createNode();
    private final StartedMockNode A = network.createNode();
    private final StartedMockNode B = network.createNode();

    @Before
    public void setup() {
        network.runNetwork();
    }

    @After
    public void tearDown() {
        network.stopNodes();
    }

    // ------------------------------------------ Issue Metal Flow Tests ----------------------------------------

    @Test
    public void transactionHasNoInputsHasOneMetalStateOutputWithTheCorrectOwner() throws Exception {

        IssueMetal flow = new IssueMetal("Gold", 10, A.getInfo().getLegalIdentities().get(0));
        CordaFuture<SignedTransaction> future = Mint.startFlow(flow);
        setup();
        SignedTransaction signedTransaction = future.get();

        assertEquals (0, signedTransaction.getTx().getInputs().size());

        assertEquals (1, signedTransaction.getTx().getOutputStates().size());
        MetalState output = signedTransaction.getTx().outputsOfType(MetalState.class).get(0);

        assertEquals(A.getInfo().getLegalIdentities().get(0), output.getOwner());

    }
}

The Error is:

java.lang.IllegalStateException: Missing the '-javaagent' JVM argument. Make sure you run the tests with the Quasar java agent attached to your JVM.
See https://docs.corda.net/head/testing.html#running-tests-in-intellij - 'Fiber classes not instrumented' for more details.

Answer 1

I would recommend using the Gradle Test Runner so that you don't have to set the javaagent flag manually.

To use Gradle Test Runner Click the Run/Debug configuration drop down > Edit Configurations... > + > Gradle In the form that appears, fill in the details:

Gradle-Project : [path to your project]

Task : :cleanTest:test

Arguments : --tests ""
