Example 12 with Neo4jError

use of org.neo4j.bolt.runtime.Neo4jError in project neo4j by neo4j.

the class MessageProcessingHandlerTest method shouldLogShortWarningOnClientDisconnectMidwayThroughQuery.

@Test
void shouldLogShortWarningOnClientDisconnectMidwayThroughQuery() throws Exception {
    // Connections dying is not exceptional per-se, so we don't need to fill the log with
    // eye-catching stack traces; but it could be indicative of some issue, so log a brief
    // warning in the debug log at least.
    // Given

    Neo4jError txTerminated = Neo4jError.from(new TransactionTerminatedException(Status.Transaction.Terminated));
    // When
    AssertableLogProvider logProvider = emulateFailureWritingError(txTerminated, outputClosed);
    // Then
    assertThat(logProvider).forClass(getClass()).forLevel(WARN).containsMessageWithArguments("Client %s disconnected while query was running. Session has been cleaned up. " + "This can be caused by temporary network problems, but if you see this often, ensure your " + "applications are properly waiting for operations to complete before exiting.", "<client>");
