### Question:
SolverHandlerConfig { public Duration getSyncInterval() { return syncInterval; } SolverHandlerConfig(String targetUserId,
                               int publishWindowSize,
                               Duration syncInterval,
                               Duration syncQueriesShift,
                               Duration usersSyncInterval,
                               Duration waitForImprovedSolutionDuration,
                               Duration improveSolutionOnBackgroundDuration); String getTargetUserId(); int getPublishWindowSize(); Duration getSyncInterval(); Duration getSyncQueriesShift(); Duration getUsersSyncInterval(); Duration getWaitForImprovedSolutionDuration(); Duration getImproveSolutionOnBackgroundDuration();  }### Answer:
@Test public void getSyncInterval() { assertThat(config.getSyncInterval()).isEqualTo(SYNC_INTERVAL); }
