TestWorkflowEnvironment GetClusterInfo is unimplemented

I’m experimenting with the Temporal Health Check, but having issues when using TestWorkflowEnvironment. Is this the expected behavior for TestWorkflowEnvironment? I’m on Java-SDK 1.3.0.

    @Test public void testGetClusterInfo() {
        TestWorkflowEnvironment testEnv = TestWorkflowEnvironment.newInstance();
        WorkflowClient client = testEnv.getWorkflowClient();
        testEnv.start();

        GetClusterInfoResponse getClusterInfoResponse = client.getWorkflowServiceStubs().blockingStub().getClusterInfo(
                GetClusterInfoRequest.newBuilder().build()
        );
        assertTrue(getClusterInfoResponse.isInitialized());
    }

Yes, TestWorkflowEnvironment doesn’t implement the gRPC methods that are not used for unit testing.

Test would pass if you used external service (real Temporal test service) in your tests, for example:

TestWorkflowEnvironment testEnv =
        TestWorkflowEnvironment.newInstance(
            TestEnvironmentOptions.newBuilder()
                .setUseExternalService(true)
                .setTarget("localhost:7233")
                .build());
