e2e_tests.test_pmtud.test_mtu_parser module

Test script to verify the MTU parsing functions work correctly.

e2e_tests.test_pmtud.test_mtu_parser.test_mtu_parsing()

Test the MTU parsing function with sample netsh, ip link show, and macOS output.

e2e_tests.test_pmtud.test_pmtud module

e2e_tests.test_pmtud.test_pmtud.get_macos_interface_name(node: BaseNode) → str

Get the interface name for the specified service using scutil on macOS.

Parameters:

node – The macOS node to execute commands on

Returns:

The interface name (e.g., “utun4”)

Return type:

str

Raises:

RuntimeError – If the scutil command fails or interface not found

e2e_tests.test_pmtud.test_pmtud.parse_linux_tunnel_mtu(ip_output: str, interface_name: str = 'CloudflareWARP') → int

Parse the MTU value for the specified interface from ip link show command output.

Parameters:

• ip_output – The output from ‘ip link show’ command

• interface_name – The name of the interface to find MTU for (default: “CloudflareWARP”)

Returns:

The MTU value for the specified interface

Return type:

int

Raises:

ValueError – If the interface is not found or MTU cannot be parsed

e2e_tests.test_pmtud.test_pmtud.parse_macos_tunnel_mtu(ifconfig_output: str, interface_name: str) → int

Parse the MTU value for the specified interface from ifconfig command output.

Parameters:

• ifconfig_output – The output from ‘ifconfig <interface>’ command

• interface_name – The name of the interface

Returns:

The MTU value for the specified interface

Return type:

int

Raises:

ValueError – If MTU cannot be parsed

e2e_tests.test_pmtud.test_pmtud.parse_windows_tunnel_mtu(netsh_output: str, interface_name: str = 'CloudflareWARP') → int

Parse the MTU value for the specified interface from netsh interface ipv4 show subinterfaces output.

Parameters:

• netsh_output – The output from ‘netsh interface ipv4 show subinterfaces’ command

• interface_name – The name of the interface to find MTU for (default: “CloudflareWARP”)

Returns:

The MTU value for the specified interface

Return type:

int

Raises:

ValueError – If the interface is not found or MTU cannot be parsed

e2e_tests.test_pmtud.test_pmtud.test_pmtud(warp: WarpActions, system: SystemActions)

Enterprise test that creates an mdm config and copies it to appropriate folder, then verifies behavior with switch_locked=true, admin override applied

e2e_tests.test_pmtud.test_pmtud.verify_tunnel_mtu(node: BaseNode, expected_mtu: int, interface_name: str = 'CloudflareWARP') → bool

Verify that the tunnel MTU matches the expected value on Windows, Linux, or macOS.

Parameters:

• node – The node to execute commands on

• expected_mtu – The expected MTU value

• interface_name – The name of the interface to check (default: “CloudflareWARP”)

Returns:

True if MTU matches expected value, False otherwise

Return type:

bool

Raises:

RuntimeError – If the command fails or interface not found
