### Question:
VersionHandler { static boolean isReadyToUpgrade() { boolean isReadyToUpgrade = false; try{ LoggingService.logDebug(MODULE_NAME, "Checking is ready to upgrade"); isReadyToUpgrade = isNotWindows() && isPackageRepositoryUpdated() && areNotVersionsSame(); LoggingService.logDebug(MODULE_NAME, "Is ready to upgrade : " + isReadyToUpgrade); } catch (Exception e){ LoggingService.logError(MODULE_NAME, "Error getting is ready to upgrade", new AgentSystemException(e.getMessage(), e)); } return isReadyToUpgrade; }    }### Answer:
@Test public void testIsReadyToUpgradeReturnsTrue() { error.add("error"); resultSetWithPath = new CommandShellResultSet<>(value, error); List<String> anotherError = new ArrayList<>(); List<String> anotherValue = new ArrayList<>(); anotherValue.add("1.2.2"); CommandShellResultSet<List<String>, List<String>> anotherResultSetWithPath = new CommandShellResultSet<>(anotherValue, anotherError); List<String> fogError = new ArrayList<>(); List<String> fogValue = new ArrayList<>(); fogValue.add("1.2.3"); CommandShellResultSet<List<String>, List<String>> fogResultSetWithPath = new CommandShellResultSet<>(fogValue, fogError); when(CommandShellExecutor.executeCommand(any())).thenReturn(resultSetWithPath, resultSetWithPath, anotherResultSetWithPath, fogResultSetWithPath); assertTrue(VersionHandler.isReadyToUpgrade()); verifyStatic(CommandShellExecutor.class, atLeastOnce()); CommandShellExecutor.executeCommand(any()); verifyStatic(LoggingService.class, atLeastOnce()); LoggingService.logDebug(MODULE_NAME, "Checking is ready to upgrade"); verifyStatic(LoggingService.class, atLeastOnce()); LoggingService.logDebug(MODULE_NAME, "Is ready to upgrade : true"); }
