I have experience working with technical brands related to telecommunications equipment and its software.

The main focus was on:

Functional testing: verifying the correctness of all declared functions of the equipment and software, including routing, switching, security, and network management.
Performance and load testing: assessing the stability of equipment under high load, measuring throughput and response time.
Compatibility testing: checking the interaction of equipment with products from other manufacturers and various operating systems/software versions.
Test automation: developing and maintaining test scripts for regression testing.

I used the following tools and technologies:

For automation: Python, with libraries like pytest or unittest.
For load testing: JMeter (to a lesser extent), specialized tools for testing network equipment (e.g., Ixia QuickTest, Spirent TestCenter — if access is available).
For working with network protocols: Wireshark.
Test management systems: TestRail.
Bug tracking systems: Jira.

An example of a simple Python test script to check network device availability via ping:

import subprocess
import platform

def ping_device(ip_address):
    """
    Checks device availability by IP address using the ping command.
    """
    param = '-n' if platform.system().lower() == 'windows' else '-c'
    command = ['ping', param, '1', ip_address] # Send 1 packet

    try:
        result = subprocess.run(command, capture_output=True, text=True, timeout=5)
        if result.returncode == 0:
            print(f"Device at {ip_address} is reachable.")
            return True
        else:
            print(f"Device at {ip_address} is unreachable. Output: {result.stdout}")
            return False
    except subprocess.TimeoutExpired:
        print(f"Timeout expired for {ip_address}.")
        return False
    except Exception as e:
        print(f"An error occurred while pinging: {e}")
        return False

# Usage example
if __name__ == "__main__":
    device_ip = "192.168.1.1" # Replace with real IP
    if ping_device(device_ip):
        print("Test passed.")
    else:
        print("Test failed.")

I also worked with telecom-specific protocols and technologies (e.g., SNMP for monitoring, various routing protocols).

Overall, experience with technical brands involves deep immersion into the technical details of the product and its specifics.
