Hi all, As (almost) all of us can see, Running BLL tests both takes considerable time, and also we have to take class loading dependencies between classes with static methods when we use mockStatic - IMHO, this is kinda frustrating. Maybe we should start get rid of PowerMock. Here is what I'm thinking of - Currently, as we use no IoC for DAOs , for tested class we do not use DbFacade.getInstance().getXXXDao()
instead we define:
protected XXXDao getXXXDao() { return DBFacade.getInstance().getXXXDao(); }
+1 for this. IMO all DAOs should be reachable from the CommandBase as this is a repeated code scattered in the various commands.
I'd suggest to create an interface that declares all of available DAOs. The new interface should be implemented by both DbFacade (which already contains that implementation) and CommandBase to assure new DAOs added to DbFacade will be added to the CommandBase as well. +1 On your idea. Too bad QueriesCommandBase and CommandBase do no share the same parent. Your idea is needed in queries as well.
And then in our tests we use Mockito to define how getXXDao acts in the test.
The following can be achieved also for config values , the following way -
protected <T> T getConfig(ConfigValues key) { return Config.<T> GetValue(key); }
And then in code (for example, in a query test) -
doReturn(5).when(query).<Integer> getConfig(any(ConfigValues.SomeIntegerConstant));
This effort can be done in small steps - a. Define getConfig method in base classes (i.e AuditLoggalbeBase). b. Rewrite parts (i.e Commands, and their tests) step by step (small commits)
Thoughts and ideas are more than welcome,
Searching for the static mocked classes brought the following list:
1 AuditLogDirector.class 1 CommandsFactory.class 1 FileUtil.class 1 LoggerFactory.class 1 QuotaHelper.class 1 QuotaManager.class 1 SchedulerUtilQuartzImpl.class 1 StopVdsCommand.class 1 TransactionSupport.class 1 VmTemplateCommand.class 2 CpuFlagsManagerHandler.class 2 StorageDomainSpaceChecker.class 2 VdsGroupDAO.class 3 EjbUtils.class 3 LogFactory.class 3 MultiLevelAdministrationHandler.class 3 StorageHelperDirector.class 3 VmTemplateHandler.class 6 ImagesHandler.class 6 VmHandler.class 10 Backend.class 28 Config.class 33 DbFacade.class
So handling the Config and DbFacade will be a major step toward powermock elimination.
