TMT Driver

jumpstarter-driver-tmt provides functionality for running TMT (Test Management Tool) commands locally while connecting to remote devices via SSH network connections. This driver allows you to execute TMT test plans and commands that provision and test remote hardware through SSH connections.

Installation

pip3 install --extra-index-url https://pkg.jumpstarter.dev/simple/ jumpstarter-driver-tmt

Configuration

Example configuration:

export:
  tmt:
    type: jumpstarter_driver_tmt.driver.TMT
    config:
      reboot_cmd: "j power cycle"
      default_username: "root"
      default_password: "somePassword"
    children:
      ssh:
        type: jumpstarter_driver_network.driver.TcpNetwork
        config:
          host: "192.168.1.100"
          port: 22
          enable_address: true

Config parameters

Parameter	Description	Type	Required	Default
reboot_cmd	Command to reboot the target device	str	no	"j power cycle"
default_username	Default username for SSH connections	str	no	""
default_password	Default password for SSH connections	str	no	""

Required Children

Child	Description	Required

Usage

CLI Commands

The TMT driver provides a CLI command tmt that allows you to run TMT commands locally while connecting to remote devices:

# assuming that your DUT has a power and storage driver
j power on
j storage flash ....

# Running part of your plan with tmt
j tmt --root . -c tracing=off -c arch=aarch64 -c distro=rhel-9 -c hw_target=rcar_s4 run --workdir-root /tmp/ -a -vv provision .. some other provisioning... plan -vv --name ^/podman/plans/fusa/tests$

# Use SSH port forwarding (if no direct connection to the DUT is possible)
j tmt --forward-ssh ....

# Specify custom username and password
j tmt --tmt-username root --tmt-password mypassword ...

# Raise log level of the tmt wrapper driver
j --log-level DEBUG tmt --root . -c tracing=off -c arch=aarch64 -c distro=rhel-9 -c hw_target=r
car_s4 run --workdir-root /tmp/ -a -vv provision .. some other provisioning... plan -vv --name ^/podman/plans/fusa/te

CLI Options

Option	Description	Default
--forward-ssh	Use SSH port forwarding for connection	false
--tmt-username	Username for SSH connections	from config
--tmt-password	Password for SSH connections	from config
--tmt-cmd	TMT command to execute	"tmt"
--tmt-on-exporter	Run TMT on the exporter (not implemented)	false

Provision Arguments Handling

The driver automatically handles TMT provision arguments by:

1. Detecting provision sections: Looks for provision or run commands in the TMT arguments
2. Replacing connection details: Automatically replaces or adds SSH connection parameters (-h connect -g <host> -P <port> -u <username> -p <password>)
3. Preserving other arguments: Keeps all other TMT arguments intact

Example of how arguments are transformed:

# Input command
j tmt run --name /my/test/plan provision -h connect -g 192.168.1.100 -P 22

# Automatically transformed to use SSH connection
# TMT receives: run --name /my/test/plan provision -h connect -g <forwarded_host> -P <forwarded_port> -u root -p password
