The testing module raises exceptions using assert statements in helper functions. While using assert statements in tests is okay, checking and raising explicit exceptions in the library is better.

For example, in this method, I suggest raising a custom exception.

	def register_agent(inventory_path, manager_path):
	with open(manager_path, 'r') as yaml_file:
	manager_path = yaml.safe_load(yaml_file)
	host = manager_path.get('ansible_host')
	internal_ip = HostInformation.get_internal_ip_from_aws_dns(host) if 'amazonaws' in host else host
	commands = [
	f"sed -i 's/<address>MANAGER_IP<\/address>/<address>{internal_ip}<\/address>/g' {WAZUH_CONF}",
	"systemctl restart wazuh-agent"
	]
	Executor.execute_commands(inventory_path, commands)
	assert internal_ip in Executor.execute_command(inventory_path, f'cat {WAZUH_CONF}'), logger.error(f'Error configuring the Manager IP ({internal_ip}) in: {HostInformation.get_os_name_and_version_from_inventory(inventory_path)} agent')

Creating custom testing module exceptions is a better solution to handle known error conditions. The pytest tests will receive these exceptions, making the test fail.
