.. _launcher: Checkbox launchers ^^^^^^^^^^^^^^^^^^ Checkbox launchers are INI files that customize checkbox experience. The customization includes: * choosing what jobs will be run * how to handle machine restart * what type of UI to use * how to handle the results Each section in the launcher is optional, when not supplied, the default values will be used. This document describes Launchers version 1. .. _launcher_config: External configuration files ============================ Launcher can specify external file(s) to load values from. ``[config]`` Beginning of the configuration section. ``config_filename`` Name of the configuration file to look for. The value may be a file name or an absolute path, and may use environment variables. If no directory is specified, the default directories where the file will be searched for are ``/etc/xdg/`` and ``~/.config/``. Default value: ``checkbox.conf`` Examples: .. code-block:: ini # Looks for ``/etc/xdg/testing.conf`` and ``~/.config/testing.conf`` [config] config_filename = testing.conf # Use an environment variable [config] config_filename = $MYCONFIGS/testing.conf # Use an absolute path [config] config_filename = /home/ubuntu/next-testing.conf For more details about value resolution order, see :doc:`../explanation/configs`. Launcher meta-information ========================= Launcher meta-information helps to provide consistent checkbox behavior in the future. ``[launcher]`` Beginning of the launcher meta-information section. ``app_id`` This fields helps to differentiate between checkbox front-ends. This way sessions started with launcher with one ``app_id`` won't interfere with sessions started with a different launcher (provided it has ``app_id`` set to other value). The app_id should be in a IQN form. Default value: ``com.canonical:checkbox-cli`` ``app_version`` This field is purely informational. ``launcher_version`` Version of the launcher language syntax and semantics to use. ``api_flags`` API flags variable determines optional feature set. List of API flags that this launcher requires. Items should be separated by spaces or commas. The default value is an empty list. ``api_version`` API version determines the behavior of the launcher. Each checkbox feature is added at a specific API version. Default behaviors don't change silently; explicit launcher change is required. Default value: ``0.99`` ``session_title`` A title to be applied to the sessions created using this launcher. This can be be used to identify a stored sessions and can be used in report generation. ``session_desc`` A string that can be applied to sessions created using this launcher. Useful for storing some contextual information about the session. ``stock_reports`` Stock reports are shortcuts in creating common reports. Instead of having to specify exporter, transport and a report section in a launcher, you can use any number of the stock ones. In launchers version 1 there are 4 stock reports you may use: * ``text``: Print results as text on standard output * ``submission_files``: Write ``html``, ``json`` and ``tar.xz`` files to ``$XDG_DATA_HOME`` directory (or to ``~/.local/share/`` if ``$XDG_DATA_HOME`` is not defined) * ``certification``: Send results to certification site * ``certification-staging``: Send results to staging version of certification site If you don't want to have any stock report automatically generated use ``none`` as the value. This field is a list; use commas or spaces to separate stock reports. The default value: ``text, certification, submission_files``. When using ``certification`` stock report, the ``secure_id`` variable may be overridden by the launcher. To do this define ``secure_id`` in a ``transport:c3`` section (this is the transport that's used by the ``certification`` stock reports). Launcher section example: .. code-block:: ini [launcher] app_id = com.foobar:system-testing launcher_version = 1 stock_reports = text session_title = MegaCorp Thingy Alpha-1 session_desc = Testing the alpha-1 release of MegaCorp Thingy including feature X Launcher using all defaults with overridden secure_id: .. code-block:: ini [transport:c3] secure_id = 001122334455667788 Launcher that disables all stock reports: .. code-block:: ini [launcher] app_id = com.foobar:system-testing launcher_version = 1 stock_reports = none Test plan section ================= This section provides control over which test plans are visible in the menus and optionally forces the app to use particular one. ``[test plan]`` Beginning of the test plan section. ``unit`` An ID of a test plan that should be selected by default. By default nothing is selected. ``filter`` Glob that test plan IDs have to match in order to be visible. Default value: ``*`` ``forced`` If set to ``yes``, test plan selection screen will be skipped. Requires ``unit`` field to be set. Default value: ``no``. Test selection section ====================== This section provides control over test selection. ``[test selection]`` Beginning of the test selection section ``forced`` If set to ``yes``, test selection screen will be skipped and all test specified in the test plan will be selected. Default value: ``no`` ``exclude`` List of regex patterns that job ids will be matched against. The matched jobs will be excluded from running in both stages of the session: bootstrapping and normal stage. Note that if you specify a pattern that matches a resource job that is used to instantiate template units those units won't get generated. The patterns should be separated with whitespace. Examples: Exclude all jobs containing 'bluetooth' in their id: .. code-block:: ini [test selection] exclude = .*bluetooth.* Exclude all jobs containing ``bluetooth`` in their id, or having ids starting with ``com.canonical.certification::dock/wireless``: .. code-block:: ini [test selection] exclude = .*bluetooth.* com.canonical.certification::dock/wireless.* Note: Exclude field set in launcher can be overridden in a config, following Checkbox values resolution order. See :doc:`configs <../explanation/configs>` for more info. Note: To clear the exclude list use... :: exclude = ...in your 'last' config. .. _launcher_ui: User Interface section ====================== This section controls which type of UI to use. ``[ui]`` Beginning of the user interface section ``type`` Type of UI to use: * ``interactive`` runs the standard Checkbox command line version that prompts user in non-automated tests. * ``silent`` skips the tests that would require human interaction. This UI type requires forcing test selection and test plan selection. It's not 'silent' in the traditional command-line tool sense. * ``converged`` launches the QML interface. It requires ``checkbox-converged`` to be installed on your system. * ``converged-silent`` launches the QML interface and skips the tests that would require human interaction. It requires ``checkbox-converged`` to be installed on your system. This UI type requires forcing test selection and test plan selection. Default value: ``interactive``. ``dont_suppress_output`` .. warning:: This field is deprecated, use 'output' to specify which jobs should have their output printed to the screen. Setting this field to ``yes`` disables hiding of command output for jobs of type ``resource`` and ``attachment``. Default value: ``no``. ``output`` This setting lets you hide output of commands run by checkbox. It can be set to one of the following values: - ``show`` - output of all jobs will be printed - ``hide-resource-and-attachment`` - output of resource and attachment jobs will be hidden, output of other job types will be printed - ``hide-automated`` - output of shell jobs as well as attachment and resource jobs will be hidden. Only interactive job command's output will be shown - ``hide`` - same as ``hide-automated``. This value is deprecated, use ``hide-automated`` Default value: ``show`` .. note:: Individual jobs can have their output hidden by specifying 'suppress-output' in their definition. ``verbosity`` This setting makes checkbox report more information from checkbox internals. Possible values are: - ``normal`` - report only warnings and errors. - ``verbose`` - report important events that take place during execution (E.g. adding units, starting jobs, changing the state of the session) - ``debug`` - print out everything Default value: ``normal`` .. note:: You can also change this behavior when invoking Checkbox by using ``--verbose`` and ``--debug`` options respectively. ``auto_retry`` If set to ``yes``, all failed jobs will automatically be retried at the end of the testing session. In addition, the re-run screen (where user can select failed and skipped jobs to re-run) will not be shown. Default value: ``no``. .. note:: You can use ``auto-retry=no`` inline in the test plan to exclude a job from auto-retrying. For more details, see :doc:`../how-to/launcher/auto-retry`. ``max_attempts`` Defines the maximum number of times a job should be run in auto-retry mode. If the job passes, it won't be retried even if the maximum number of attempts have not been reached. Default value: ``3``. ``delay_before_retry`` The number of seconds to wait before retrying the failed jobs at the end of the testing session. This can be useful when the jobs rely on external factors (e.g. a WiFi access point) and you want to wait before retrying the same job. Default value: ``1``. Restart section =============== This section enables fine control over how checkbox is restarted. ``[restart]`` Beginning of the restart section ``strategy`` Override the restart strategy that should be used. Currently supported strategies are ``XDG`` and ``Snappy``. By default the best strategy is determined at runtime. Environment section =================== ``[environment]`` Beginning of the environment section Each variable present in the ``environment`` section will be present as environment variable for all jobs run. Example: .. code-block:: ini [environment] TESTING_HOST = 192.168.0.100 .. _generating-reports: Daemon-specific configuration ============================= ``[agent]`` .. warning:: This section was previously called ``[daemon]``. This term has been deprecated as of Checkbox 2.9 and is planned for removal. Beginning of the agent-specific section. Settings in this section only apply to sessions that are run by :term:`Checkbox Agent` spawned as Systemd service. ``normal_user`` Username to use when job doesn't specify which user to run as. The systemd service run on the :term:`agent` is run by root so in order to run some jobs as an unprivileged user this variable can be used. Manifest section ================ ``[manifest]`` Beginning of the manifest section. Each variable present in the ``manifest`` section will be used as a preset value for the system manifest, taking precedence over the disk cache. Example: .. code-block:: ini [manifest] com.canonical.certification::has_touchscreen = yes com.canonical.certification::has_usb_type_c = true com.canonical.certification::foo = 23 Generating reports ================== Creation of reports is governed by three sections: ``report``, ``exporter``, and ``transport``. Each of those sections might be specified multiple times to provide more than one report. Exporter -------- ``[exporter:exporter_name]`` Beginning of an exporter declaration. Note that ``exporter_name`` should be replaced with something meaningful, like ``html``. ``unit`` ID of an exporter to use. To get the list of available exporters on your system run ``$ checkbox-cli list exporter``. ``options`` A list of options that will be supplied to the exporter. Items should be separated by spaces or commas. Example: .. code-block:: ini [exporter:html] unit = com.canonical.plainbox::html Transport --------- ``[transport:transport_name]`` Beginning of a transport declaration. Note that ``transport_name`` should be replaced with something meaningful, like ``standard_out``. ``type`` Type of a transport to use. Allowed values are: ``stream``, ``file``, and ``submission-service``. Depending on the type of transport there might be additional fields. +------------------------+---------------+----------------+----------------------+ | transport type | variables | meaning | example | +========================+===============+================+======================+ | ``stream`` | ``stream`` | which stream to| ``[transport:out]`` | | | | use ``stdout`` | | | | | or ``stderr`` | ``type = stream`` | | | | | | | | | | ``stream = stdout`` | +------------------------+---------------+----------------+----------------------+ | ``file`` | ``path`` | where to save | ``[transport:f1]`` | | | | the file | | | | | | ``type = file`` | | | | | | | | | | ``path = ~/report`` | +------------------------+---------------+----------------+----------------------+ | ``submission-service`` | ``secure-id`` | secure-id to | ``[transport:c3]`` | | | | use when | | | | | uploading to | ``type = sub`` \ | | | | certification | ``mission-service`` | | | | sites | | | | | | ``secure_id = 01``\ | | | | | ``23456789ABCD`` | | +---------------+----------------+ | | | ``staging`` | determines if | ``staging = yes`` | | | | staging site | | | | | should be used | | | | | Default: | | | | | ``no`` | | | | | | | | | | | | | | | | | +------------------------+---------------+----------------+----------------------+ Report ------ ``[report:report_name]`` Beginning of a report declaration. Note that ``report_name`` should be replaced with something meaningful, like ``to_screen``. ``exporter`` Name of the exporter to use ``transport`` Name of the transport to use ``forced`` If set to ``yes`` will make checkbox always produce the report (skipping the prompt). Default value: ``no``. Example of all three sections working to produce a report: .. code-block:: ini [exporter:text] unit = com.canonical.plainbox::text [transport:out] type = stream stream = stdout [report:screen] exporter = text transport = out forced = yes Launcher examples ================= 1) Fully automatic run of all tests from 'com.canonical.certification::smoke' test plan concluded by producing text report to standard output. .. code-block:: ini #!/usr/bin/env checkbox-cli [launcher] launcher_version = 1 app_id = com.canonical.certification:smoke-test stock_reports = text [test plan] unit = com.canonical.certification::smoke forced = yes [test selection] forced = yes [ui] type = silent [transport:outfile] type = stream stream = stdout [exporter:text] unit = com.canonical.plainbox::text [report:screen] transport = outfile exporter = text 2) Interactive testing of FooBar project. Report should be uploaded to the staging version of certification site and saved to /tmp/submission.tar.xz .. code-block:: ini #!/usr/bin/env checkbox-cli [launcher] launcher_version = 1 app_id = com.foobar:system-testing [providers] use = com.megacorp.foo::bar* [test plan] unit = com.megacorp.foo::bar-generic [ui] type = silent output = hide [transport:certification] type = certification secure-id = 00112233445566 staging = yes [transport:local_file] type = file path = /tmp/submission.tar.xz [report:c3-staging] transport = certification exporter = tar [report:file] transport = local_file exporter = tar 3) A typical launcher to run a desktop SRU test plan automatically. The launcher will automatically retry the failed test jobs. Besides, this launcher includes another launcher ``launcher.conf`` as its customized environment configuration. The launcher .. code-block:: ini #!/usr/bin/env checkbox-cli [launcher] launcher_version = 1 [config] config_filename = $HOME/launcher.conf [test plan] unit = com.canonical.certification::sru forced = yes [test selection] forced = yes [ui] type = silent auto_retry = yes max_attempts = 3 delay_before_retry = 15 The launcher configuration ``launcher.conf`` .. code-block:: ini #!/usr/bin/env checkbox-cli [launcher] launcher_version = 1 stock_reports = text, submission_files, certification [transport:c3] secure_id = [transport:local_file] type = file path = /home/ubuntu/c3-local-submission.tar.xz [exporter:example_tar] unit = com.canonical.plainbox::tar [report:file] transport = local_file exporter = tar forced = yes [environment] ROUTERS = multiple WPA_BG_SSID = foo-bar-bg-wpa WPA_BG_PSK = foo-bar WPA_N_SSID = foo-bar-n-wpa WPA_N_PSK = foobar WPA_AC_SSID = foo-bar-ac-wpa WPA_AC_PSK = foobar OPEN_BG_SSID = foo-bar-bg-open OPEN_N_SSID = foo-bar-n-open OPEN_AC_SSID = foo-bar-ac-open BTDEVADDR = ff:oo:oo:bb:aa:rr TRANSFER_SERVER = cdimage.ubuntu.com
