A new Kyua concept is added -- "execution environment". A test can be configured to be run within a specific environment. The test case lifecycle is extended respectively: - execenv init (creates a jail or does nothing for default execenv="host") - test exec - cleanup exec (optional) - execenv cleanup (removes a jail or does nothing for default execenv="host") The following new functionality is provided, from bottom to top: 1 ATF based tests - The new "execenv" metadata property can be set to explicitly ask for an execution environment: "host" or "jail". If it's not defined, as all existing tests do, then it implicitly means "host". - The new "execenv.jail.params" metadata property can be optionally defined to ask Kyua to use specific jail(8) parameters during creation of a temporary jail. An example is "vnet allow.raw_sockets". Kyua implicitly adds "children.max" to "execenv_jail_params" parameters with the maximum possible value. A test case can override it. 2 Kyuafile - The same new metadata properties can be defined on Kyuafile level: "execenv" and "execenv_jail_params". - Note that historically ATF uses dotted style of metadata naming, while Kyua uses underscore style. Hence "execenv.jail.params" vs. "execenv_jail_params". 3 kyua.conf, kyua CLI - The new "execenvs" engine configuration variable can be set to a list of execution environments to run only tests designed for. Tests of not listed environments are skipped. - By default, this variable lists all execution environments supported by a Kyua binary, e.g. execenvs="host jail". - This variable can be changed via "kyua.conf" or via kyua CLI's "-v" parameter. For example, "kyua -v execenvs=host test" will run only host-based tests and skip jail-based ones. - Current value of this variable can be examined with "kyua config". [markj] This feature has not landed upstream yet. See the discussion in https://github.com/freebsd/kyua/pull/224 . Having the ability to automatically jail tests allows many network tests to run in parallel, giving a drastic speedup. So, let's import the feature and start using it in main.
