### Question:
CommandShellExecutor { public static CommandShellResultSet<List<String>, List<String>> executeCommand(String command) { String[] fullCommand = computeCommand(command); return execute(fullCommand); }  static CommandShellResultSet<List<String>, List<String>> executeCommand(String command); static CommandShellResultSet<List<String>, List<String>> executeScript(String script, String... args); static Process executeDynamicCommand(String command,
                                                CommandShellResultSet<List<String>, List<String>> resultSet,
                                                AtomicBoolean isRun,
                                                Runnable killOrphanedProcessesRunnable); static CommandShellResultSet<V, E> executeCommand(String command, Function<CommandShellResultSet<List<String>, List<String>>, CommandShellResultSet<V, E>> mapper);  }### Answer:
@Test public void testExecuteCommandWithValidInput() { command = "echo Iofog"; value = new ArrayList<>(); value.add("Iofog"); errors = new ArrayList<>(); commandShellResultSet = new CommandShellResultSet<>(value, errors); assertEquals(commandShellResultSet, commandShellExecutor.executeCommand(command)); }
@Test public void testExecuteCommandWithInvalidCommand() { command = "some random command"; value = new ArrayList<>(); errors = new ArrayList<>(); errors.add("/bin/sh: some: command not found"); commandShellResultSet = new CommandShellResultSet<>(value, errors); assertNotNull( commandShellExecutor.executeCommand(command)); }
