the class RequestHandlerTest method shouldDefaultToDistributor.

@Test

    // Given
    givenRequestHandler(ImmutableMap.of());
    // When
    final List<ParsedStatement> statements = KSQL_PARSER.parse(SOME_STREAM_SQL);

Example 2 with ParsedStatement

use of io.confluent.ksql.parser.KsqlParser.ParsedStatement in project ksql by confluentinc.

    // When
    handler.execute(securityContext, statements, sessionProperties);
    // Then
    verify(sync).waitFor(argThat(hasItems(entity1, entity2)), any());
    // since the entities passed into sync#waitFor are always the same object, mockito
    // cannot verify the original two arguments
    verify(sync, times(3)).waitFor(any(), any());
