Classes

Class Structure

Here’s the overview of the essential classes used in the tmt project. It should help you to get quickly started and better understand the relation between the individual classes.

Basic

The Common class is the parent of most of the available classes, it provides common methods for logging, running commands and workdir handling. The Core class together with its child classes Test, Plan and Story cover the Metadata Specification:

Attributes

Object hierarchy is following: Run -> Plans -> Steps -> Plugins, where the Run is on the top of this hierarchy. The objects have the parent attribute, that is pointing to the parent in which the current instance is contained.

The node attribute of Test, Plan and Story instances references the original leaf node of the fmf metadata tree from which the respective test, plan or story have been created.

In a similar way, the tree property of the Tree instance points to the original fmf.Tree from which it was initialized.

Class Conversions

Various internal objects and classes often need to be converted from their Python nature to data that can be saved, loaded or exported in different form. To facilitate these conversions, three families of helper methods are provided, each with its own set of use cases.

to_spec/to_minimal_spec/from_spec

This family of methods works with tmt specification, i.e. raw user-provided data coming from fmf files describing plans, tests, stories, or from command-line options. from_spec() shall be called to spawn objects representing the user input, while to_spec() should produce output one could find in fmf files.

The default implementation comes from tmt.utils.SpecBasedContainer class, all classes based on user input data should include this class among their bases.

to_minimal_spec performs the identical operation as to_spec, but its result should not include keys that are optional and not set, while to_spec should always include all keys, even when set to default values or not set at all.

# Create an fmf id object from raw data
fmf_id = tmt.base.FmfId.from_spec({'url': ..., 'ref': ...})

to_serialized/from_serialized/unserialize

This family of methods is aiming at runtime objects that may be saved into and loaded from tmt working files, i.e. files tmt uses to store a state in its workdir, like step.yaml or guests.yaml.

Third member of this family, unserialize, is similar to from_serialized - both create an object from its serialized form, only unserialize is capable of detecting the class to instantiate while for using from_serialized, one must already know which class to work with. unserialize then uses from_serialized under the hood to do the heavy lifting when correct class is identified.

The default implementation comes from tmt.utils.SerializableContainer class, all classes that are being saved and loaded during tmt run should include this class among their bases.

See https://en.wikipedia.org/wiki/Serialization for more details on the concept of serialization.

 # tmt.steps.discover.shell.DiscoverShellData wishes to unserialize its
 # `tests` a list of `TestDescription` objects rather than a list of
 # dictionaries (the default implementation).
 @classmethod
 def from_serialized(cls, serialized: Dict[str, Any]) -> 'DiscoverShellData':
     obj = super().from_serialized(serialized)

     obj.tests = [TestDescription.from_serialized(
         serialized_test) for serialized_test in serialized['tests']]

     return obj

# A step saving its state...
content: Dict[str, Any] = {
    'status': self.status(),
    'data': [datum.to_serialized() for datum in self.data]
}
self.write('step.yaml', tmt.utils.dict_to_yaml(content))

# ... and loading it back.
# Note the use of unserialize(): step data may have been serialized from
# various different classes (derived from tmt.steps.provision.Guest),
# and unserialize() will detect the correct class.
raw_step_data: Dict[Any, Any] = tmt.utils.yaml_to_dict(self.read('step.yaml'))
self.data = [
    StepData.unserialize(raw_datum) for raw_datum in raw_step_data['data']
]

to_dict/to_minimal_dict

Very special helper methods: its use cases are not related to any input or output data, and most of the time, when in need of iterating over object’s keys and/or values, one can use keys(), values() or items() methods. They are used as sources of data for serialization and validation, but they usually have no use outside of default implementations.

Warning

If you think of using to_dict(), please, think again and be sure you know what are you doing. Despite its output being sometimes perfectly compatible with output of to_serialized() or to_spec(), it is not generaly true, and using it instead of proper methods may lead to unexpected exceptions.

The same applies to to_minimal_dict().

# tmt.base.FmfId's specification is basically just a mapping,
# therefore `to_dict()` is good enough to produce a specification.
def to_spec(self) -> Dict[str, Any]:
     return self.to_dict()

Commands vs. shell scripts

tmt internals makes distinction between a command and a shell script. This is important to enforce proper handling of shell scripts specified by users - prepare and finish scripts, test commands, etc.

There are two basic types for describing commands:

  • tmt.utils.Command - a list of “command elements” representing an executable followed by its arguments. Common throughout tmt’s code, never used with shell=True. This is the only form accepted by tmt.utils.Common.run() method.

  • tmt.utils.ShellScript - a free-form string containing a shell script, from a single built-in command to multiline complex scripts. Traditionally, this kind of “commands” is accompanied by shell=True, tmt code converts ShellScript values into Command elements, e.g. with the help of the ShellScript.to_element() method.

Following rules apply:

  • tmt code shall stick to Command and ShellScript types when passing commands between functions and classes. There should be no need for custom types like List[str] or str, the preferred types are equipped with necessary conversion helpers.

  • in most cases, tmt is given scripts by users, not executable commands with options. Plugin writers should avoid using bare str or Command types when annotating this kind of input. For example:

    class FooStepData(tmt.steps.StepData):
  # `--script ...` option dictates step data to have a field of correct type
  script: List[tmt.utils.ShellScript]

...
def go(self):
  ...

  # When calling `get()`, hint type linters with the right type
  scripts: List[tmt.utils.ShellScript] = self.get('script')

  • shell=True should not be needed, use ShellScript.to_shell_command() instead.

Both ShellScript and Command support addition, therefore it’s possible to build up commands and scripts from smaller building blocks:

>>> command = Command('ls')
>>> command += Command('-al')
>>> command += ['/']
>>> str(command)
'ls -al /'

>>> script = ShellScript('ls -al')
>>> script += ShellScript('ls -al $HOME')
>>> str(script)
'ls -al; ls -al $HOME'

There are several functions available to help with conversion between command and shell script format:

Command.to_element

Convert a command - or possibly just command options - to a command element. Useful when you got a list of command options that another command is expecting as its options:

>>> ssh_command = Command('ssh', '-o', 'ForwardX11=yes', '-o', 'IdentitiesOnly=yes')
>>> command = Command('rsync', '-e', ssh_command.to_element())
>>> str(command)
"rsync -e 'ssh -o ForwardX11=yes -o IdentitiesOnly=yes'"

Command.to_script

Convert a command to a shell script:

>>> command1 = Command('ls', '-al', '/')
>>> command2 = Command('bash', '-c', command1.to_script().to_element())
>>> str(command2)
"bash -c 'ls -al /'"

Script.to_element

Convert a shell script to a command element:

>>> command = Command('bash', '-c', ShellScript('ls -al /').to_element())
>>> str(command)
"bash -c 'ls -al /'"

Script.from_scripts

Convert a list of shell scripts into a single script. Useful when building a script from multiple steps:

>>> scripts: List[ShellScript] = [
...   ShellScript('cd $HOME'),
...   ShellScript('ls -al')
... ]
>>>
>>> if True:
...   scripts.append(ShellScript('rm -f bar'))
...
>>> script = ShellScript.from_scripts(scripts)
>>> str(script)
'cd $HOME; ls -al; rm -f bar'

Script.to_shell_command

Convert a shell script into a shell-driven command. This is what shell=True would do, but it makes it explicit and involves correct type conversion:

>>> script = ShellScript("""
... cd $HOME
... ls -al
... """)
>>> command = script.to_shell_command()
>>> str(command)
"/bin/bash -c '\ncd $HOME\nls -al\n'"

Essential Classes

Clean workdirs of runs

class tmt.Guest(*, data: GuestData, name: Optional[str] = None, parent: Optional[Common] = None, logger: Logger)

Guest provisioned for test execution

A base class for guest-like classes. Provides some of the basic methods and functionality, but note some of the methods are left intentionally empty. These do not have valid implementation on this level, and it’s up to Guest subclasses to provide one working in their respective infrastructure.

The following keys are expected in the ‘data’ container:

role ....... guest role in the multihost scenario
guest ...... name, hostname or ip address

These are by default imported into instance attributes.

ansible(playbook: str, extra_args: Optional[str] = None) → None

Prepare guest using ansible playbook

details() → None

Show guest details such as distro and kernel

execute(command: ShellScript, cwd: Optional[str] = None, env: Optional[Dict[str, str]] = None, friendly_command: Optional[str] = None, test_session: bool = False, silent: bool = False, log: Optional[BaseLoggerFnType] = None, interactive: bool = False, **kwargs: Any) → CommandOutput
execute(command: Command, cwd: Optional[str] = None, env: Optional[Dict[str, str]] = None, friendly_command: Optional[str] = None, test_session: bool = False, silent: bool = False, log: Optional[BaseLoggerFnType] = None, interactive: bool = False, **kwargs: Any) → CommandOutput

Execute a command on the guest.

Parameters

  • command – either a command or a shell script to execute.

  • cwd – if set, execute command in this directory on the guest.

  • env – if set, set these environment variables before running the command.

  • friendly_command – nice, human-friendly representation of the command.

guest: Optional[str]
property is_ready: bool

Detect guest is ready or not

load(data: GuestData) → None

Load guest data into object attributes for easy access

Called during guest object initialization. Takes care of storing all supported keys (see class attribute _keys for the list) from provided data to the guest object attributes. Child classes can extend it to make additional guest attributes easily available.

Data dictionary can contain guest information from both command line options / L2 metadata / user configuration and wake up data stored by the save() method below.

localhost = False
classmethod options(how: Optional[str] = None) → List[Callable[[Any], Any]]

Prepare command line options related to guests

pull(source: Optional[str] = None, destination: Optional[str] = None, options: Optional[List[str]] = None, extend_options: Optional[List[str]] = None) → None

Pull files from the guest

push(source: Optional[str] = None, destination: Optional[str] = None, options: Optional[List[str]] = None) → None

Push files to the guest

reboot(hard: bool = False, command: Optional[Union[Command, ShellScript]] = None, timeout: Optional[int] = None) → bool

Reboot the guest, return True if successful

Parameter ‘hard’ set to True means that guest should be rebooted by way which is not clean in sense that data can be lost. When set to False reboot should be done gracefully.

Use the ‘command’ parameter to specify a custom reboot command instead of the default ‘reboot’.

Parameter ‘timeout’ can be used to specify time (in seconds) to wait for the guest to come back up after rebooting.

reconnect(timeout: Optional[int] = None, tick: float = 5, tick_increase: float = 1.0) → bool

Ensure the connection to the guest is working

The default timeout is 5 minutes. Custom number of seconds can be provided in the timeout parameter. This may be useful when long operations (such as system upgrade) are performed.

remove() → None

Remove the guest

Completely remove all guest instance data so that it does not consume any disk resources.

classmethod requires() → List[str]

No extra requires needed

role: Optional[str]
save() → GuestData

Save guest data for future wake up

Export all essential guest data into a dictionary which will be stored in the guests.yaml file for possible future wake up of the guest. Everything needed to attach to a running instance should be added into the data dictionary by child classes.

start() → None

Start the guest

Get a new guest instance running. This should include preparing any configuration necessary to get it started. Called after load() is completed so all guest data should be available.

stop() → None

Stop the guest

Shut down a running guest instance so that it does not consume any memory or cpu resources. If needed, perform any actions necessary to store the instance status to disk.

wake() → None

Wake up the guest

Perform any actions necessary after step wake up to be able to attach to a running guest instance and execute commands. Called after load() is completed so all guest data should be prepared.

class tmt.GuestSsh(*, data: GuestData, name: Optional[str] = None, parent: Optional[Common] = None, logger: Logger)

Guest provisioned for test execution, capable of accepting SSH connections

The following keys are expected in the ‘data’ dictionary:

role ....... guest role in the multihost scenario (inherited)
guest ...... hostname or ip address (inherited)
port ....... port to connect to
user ....... user name to log in
key ........ path to the private key (str or list)
password ... password

These are by default imported into instance attributes.

ansible(playbook: str, extra_args: Optional[str] = None) → None

Execute a command on the guest.

Parameters

  • command – either a command or a shell script to execute.

  • cwd – execute command in this directory on the guest.

Pull files from the guest

By default the whole plan workdir is synced from the same location on the guest. Use the ‘source’ and ‘destination’ to sync custom location, the ‘options’ parameter to modify default options DEFAULT_RSYNC_PULL_OPTIONS and ‘extend_options’ to extend them (e.g. by exclude).

push(source: Optional[str] = None, destination: Optional[str] = None, options: Optional[List[str]] = None) → None

Push files to the guest

By default the whole plan workdir is synced to the same location on the guest. Use the ‘source’ and ‘destination’ to sync custom location and the ‘options’ parametr to modify default options which are ‘-Rrz –links –safe-links –delete’.

reboot(hard: bool = False, command: Optional[Union[Command, ShellScript]] = None, timeout: Optional[int] = None, tick: float = 30.0, tick_increase: float = 1.0) → bool

Reboot the guest, return True if reconnect was successful

Parameter ‘hard’ set to True means that guest should be rebooted by way which is not clean in sense that data can be lost. When set to False reboot should be done gracefully.

Use the ‘command’ parameter to specify a custom reboot command instead of the default ‘reboot’.

remove() → None

Remove the guest

Completely remove all guest instance data so that it does not consume any disk resources.

ssh_option: List[str]
stop() → None

class tmt.Logger(actual_logger: Logger, base_shift: int = 0, verbosity_level: int = 0, debug_level: int = 0, quiet: bool = False)

A logging entry point, representing a certain level of verbosity and handlers.

Provides actual logging methods plus methods for managing verbosity levels and handlers.

Attach console handler to this logger

add_logfile_handler(filepath: str) → None

Attach a log file handler to this logger

apply_verbosity_options(**kwargs: Any) → Logger

Update logger’s settings to match given CLI options.

Use this method to update logger’s settings after Logger.descend() call, to reflect options given to a tmt subcommand.

clone() → Logger

Create a copy of this logger instance.

All its settings are propagated to new instance. Settings are not shared, and may be freely modified after cloning without affecting the other logger.

classmethod create(actual_logger: Optional[Logger] = None, **verbosity_options: Any) → Logger

Create a (root) tmt logger.

This method has a very limited set of use cases:

  • CLI bootstrapping right after tmt started.

  • Unit tests of code that requires logger as one of its inputs.

  • 3rd party apps treating tmt as a library, i.e. when they wish tmt to use their logger instead of tmt’s default one.

Parameters

actual_logger – a logging.Logger instance to wrap. If not set, a default logger named tmt is created.

debug(key: str, value: Optional[str] = None, color: Optional[str] = None, shift: int = 0, level: int = 1) → None
descend(logger_name: Optional[str] = None, extra_shift: int = 1) → Logger

Create a copy of this logger instance, but with a new raw logger.

New logging.Logger instance is created from our raw logger, forming a parent/child relationship betwen them, and it’s then wrapped with Logger instance. Settings of this logger are copied to new one, with the exception of base_shift which is increased by one, effectively indenting all messages passing through new logger.

Parameters

  • logger_name – optional name for the underlying logging.Logger instance. Useful for debugging. If not set, a generic one is created.

  • extra_shift – by how many extra levels should messages be indented by new logger.
