### Question:
UtilsManager { public List<DefaultSystemParameter> getSystemParameters() { List<DefaultSystemParameter> defaultSystemParameterList = preferenceManager.getPreference( SystemPreferences.LAUNCH_SYSTEM_PARAMETERS); return defaultSystemParameterList != null ? defaultSystemParameterList : Collections.emptyList(); }  String buildSshUrl(Long runId); String buildFSBrowserUrl(Long runId); List<DefaultSystemParameter> getSystemParameters();  }### Answer:
@Test @Transactional(propagation = Propagation.REQUIRES_NEW, rollbackFor = Throwable.class) public void testGetSystemParameters() throws IOException { File parametersJson = context.getResource("classpath:templates/default_parameters.json").getFile(); Preference pref = SystemPreferences.LAUNCH_SYSTEM_PARAMETERS.toPreference(); pref.setValue(Files.readAllLines(parametersJson.toPath()).stream().collect(Collectors.joining())); preferenceManager.update(Collections.singletonList(pref)); List<DefaultSystemParameter> params = utilsManager.getSystemParameters(); Assert.assertFalse(params.isEmpty()); }
