[root@node1 salt]# salt web1 sys.doc test
test.arg: Print out the data passed into the function ``*args`` and ```kwargs``, this is used to both test the publication data and cli argument passing, but also to display the information available within the publication data. Returns {"args": args, "kwargs": kwargs}. CLI Example: salt '*' test.arg 1 "two" 3.1 txt="hello" wow='{a: 1, b: "hello"}' test.arg_repr: Print out the data passed into the function ``*args`` and ```kwargs``, this is used to both test the publication data and cli argument passing, but also to display the information available within the publication data. Returns {"args": repr(args), "kwargs": repr(kwargs)}. CLI Example: salt '*' test.arg_repr 1 "two" 3.1 txt="hello" wow='{a: 1, b: "hello"}' test.arg_type: Print out the types of the args and kwargs. This is used to test the types of the args and kwargs passed down to the minion CLI Example: salt '*' test.arg_type 1 'int' test.assertion: Assert the given argument CLI Example: salt '*' test.assertion False test.attr_call: Call grains.items via the attribute CLI Example: salt '*' test.attr_call test.collatz: Execute the collatz conjecture from the passed starting number, returns the sequence and the time it took to compute. Used for performance tests. CLI Example: salt '*' test.collatz 3 test.conf_test: Return the value for test.foo in the minion configuration file, or return the default value CLI Example: salt '*' test.conf_test test.cross_test: Execute a minion function via the __salt__ object in the test module, used to verify that the minion functions can be called via the __salt__ module. CLI Example: salt '*' test.cross_test file.gid_to_group 0 test.echo: Return a string - used for testing the connection CLI Example: salt '*' test.echo 'foo bar baz quo qux' test.exception: Raise an exception Optionally provide an error message or output the full stack. CLI Example: salt '*' test.exception 'Oh noes!' test.false: Always return False CLI Example: salt '*' test.false test.fib: Return the num-th Fibonacci number, and the time it took to compute in seconds. Used for performance tests. This function is designed to have terrible performance. CLI Example: salt '*' test.fib 3 test.get_opts: Return the configuration options passed to this minion CLI Example: salt '*' test.get_opts test.kwarg: Print out the data passed into the function ``**kwargs``, this is used to both test the publication data and cli kwarg passing, but also to display the information available within the publication data. CLI Example: salt '*' test.kwarg num=1 txt="two" env='{a: 1, b: "hello"}' test.module_report: Return a dict containing all of the execution modules with a report on the overall availability via different references CLI Example: salt '*' test.module_report test.not_loaded: List the modules that were not loaded by the salt loader system CLI Example: salt '*' test.not_loaded test.opts_pkg: Return an opts package with the grains and opts for this minion. This is primarily used to create the options used for master side state compiling routines CLI Example: salt '*' test.opts_pkg test.outputter: Test the outputter, pass in data to return CLI Example: salt '*' test.outputter foobar test.ping: Used to make sure the minion is up and responding. Not an ICMP ping. Returns ``True``. CLI Example: salt '*' test.ping test.provider: Pass in a function name to discover what provider is being used CLI Example: salt '*' test.provider service test.providers: Return a dict of the provider names and the files that provided them CLI Example: salt '*' test.providers test.rand_sleep: Sleep for a random number of seconds, used to test long-running commands and minions returning at differing intervals CLI Example: salt '*' test.rand_sleep 60 test.rand_str: Return a random string size size of the string to generate hash_type hash type to use New in version 2015.5.2 CLI Example: salt '*' test.rand_str test.retcode: Test that the returncode system is functioning correctly CLI Example: salt '*' test.retcode 42 test.sleep: Instruct the minion to initiate a process that will sleep for a given period of time. CLI Example: salt '*' test.sleep 20 test.stack: Return the current stack trace CLI Example: salt '*' test.stack test.true: Always return True CLI Example: salt '*' test.true test.try_: Try to run a module command. On an exception return None. If `return_try_exception` is set True return the exception. This can be helpful in templates where running a module might fail as expected. CLI Example: <pre> {% for i in range(0,230) %} {{ salt['test.try'](module='ipmi.get_users', bmc_host='172.2.2.'+i)|yaml(False) }} {% endfor %} </pre> test.tty: Deprecated! Moved to cmdmod. CLI Example: salt '*' test.tty tty0 'This is a test' salt '*' test.tty pts3 'This is a test' test.version: Return the version of salt on the minion CLI Example: salt '*' test.version test.versions: This function is an alias of ``versions_report``. Returns versions of components used by salt CLI Example: salt '*' test.versions_report test.versions_information: Report the versions of dependent and system software CLI Example: salt '*' test.versions_information test.versions_report: Returns versions of components used by salt CLI Example: salt '*' test.versions_report
