+#### Functional
+
+###### Can you confirm that the `backup_manager.py` and `backup_service.py` are present?
+
+##### Run the following command `python3 ./backup_manager.py create "test2;18:15;backup_test2"`
+
+###### Can you confirm that the `backup_schedules.txt` was created?
+
+##### Run the following command `cat backup_schedules.txt`.
+
+```bash
+$ cat backup_schedules.txt
+test2;18:15;backup_test2
+```
+
+###### Was the schedule created properly, with the same format as the example above?
+
+##### Run the following command `python3 ./backup_manager.py stop`.
+
+###### Can you confirm that the `logs` folder was created and inside of it is the `backup_manager.log`?
+
+##### Now run the command `cat logs/backup_manager.log`.
+
+```bash
+$ cat logs/backup_manager.log
+[13/02/2023 17:14] Error: cannot kill the service
+```
+
+###### Can you confirm that the `backup_manager.log` file contains an error like the one above, stating that the service is already stopped?
+
+##### Create a couple more backup schedules using the command `python3 ./backup_manager.py create "file;HH:MM;backup_name"`
+
+##### Run the command `python3 ./backup_manager.py list`.
+
+```bash
+$ python3 ./backup_manager.py list
+0: test2;18:15;backup_test2
+1: test3;18:16;backup_test3
+2: test4;18:17;backup_test4
+```
+
+###### Did you get a result like the one above, with the schedule you created attached with an index at the beginning, on your terminal?
+
+##### Run the command `python3 ./backup_manager.py delete 1`.
+
+```bash
+$ python3 ./backup_manager.py list
+0: test2;18:15;backup_test2
+1: test4;18:17;backup_test4
+```
+
+###### Was the task with the index `1` removed from the list? Use `python3 ./backup_manager.py list`to.
+
+##### Verify that the following command runs without errors: `python3 backup_manager.py start`.
+
+###### Can you confirm that the `backup_service.py` process is running by using the command `ps -ef | grep backup_service`?
+
+##### Now run the command `python3 backup_manager.py start` again.
+
+```bash
+$ python3 ./backup_manager.py start
+$ cat logs/backup_manager.log
+[13/02/2023 17:14] Error: service already running
+```
+
+###### Can you confirm bu running the command `cat logs/backup_manager.log` if the log file contains an error like the one above, stating that the service is already running?
+
+##### Run `python3 backup_manager.py stop` and delete everything that was created until now, the `logs` folder and the `backup_schedules.txt`. Lets create the backup manually.
+
+##### Run the following command by order:
+
+    1- mkdir testing; cd testing; touch 1 2 3; cd ../
+    2- python3 ./backup_manager.py create "testing;"Current_hour";backup_test".
+    3- python3 ./backup_manager.py start
+    4- python3 ./backup_manager.py backups
+
+```bash
+$ mkdir testing; cd testing; touch 1 2 3; cd ../
+$ ls
+backup_manager.py  backup_service.py  testing/
+$ python3 ./backup_manager.py create "testing;18:21;backup_test"
+$ python3 ./backup_manager.py list
+0: testing;18:21;backup_test
+$ python3 ./backup_manager.py start
+$ python3 ./backup_manager.py backups
+backup_test.tar
+$ ls
+backup_manager.py  backups/  backup_schedules.txt  backup_service.py  logs/ testing/
+$ cat logs/backup_manager.log
+[13/02/2023 18:20] Schedule created
+[13/02/2023 18:20] Show schedule list
+[13/02/2023 18:21] Backup list
+$ cat backup_schedules.txt
+testing;18:21;backup_test
+$ cat logs/backup_service.log
+[13/02/2023 18:21] Backup done for testing in backups/backup_test.tar
+```
+
+##### Can you confirm that the backup was created successfully? Follow the example above.
+
+### Error handling
+
+##### Verify error handling for incorrect commands and incorrect arguments. For example, confirm that an error message is displayed when attempting to run the command `python3 backup_manager.py invalid_command`.
+
+```bash
+$ python3 backup_manager.py invalid_command
+Error: unknown instruction
+```
+
+###### Was the error message displayed?
+
+##### Run `python3 backup_manager.py stop` and delete everything that was created until now, the `logs` folder and the `backup_schedules.txt`. After that run the following commands:
+
+    1- python3 backup_manager.py stop
+    2- python3 ./backup_manager.py create "wrong_format"
+    3- python3 ./backup_manager.py backups
+    4- python3 ./backup_manager.py start
+    5- python3 ./backup_manager.py start
+
+```bash
+$ cat logs/backup_manager.log
+[14/02/2023 15:07] Error: cannot kill the service
+[14/02/2023 15:07] Error: invalid schedule format
+[14/02/2023 15:08] Error: [Errno 2] No such file or directory: "./backups"
+[14/02/2023 15:08] Error: service already running
+$ cat logs/backup_service.log
+[14/02/2023 15:11] Error: cannot open backup_schedules
+
+```
+
+###### Can you confirm that all error messages have been saved in the log files like in the example above?
+
+##### Go to the code of the project adn check if the creator used `try` and `catch` to handle the errors.
+
+###### Did he use `try` and `catch` to handle the errors?
