Test Suite Support Macros

%%% %%%

The config macro is defined in ct.hrl. This %%% macro should be used to retrieve information from the %%% Config variable sent to all test cases. It is used with two %%% arguments, where the first is the name of the configuration %%% variable you wish to retrieve, and the second is the Config %%% variable supplied to the test case.

%%% %%%

Possible configuration variables include:

%%% %%% @type var_name() = atom(). A variable name which is specified when %%% ct:require/2 is called, %%% e.g. ct:require(mynodename,{node,[telnet]}) %%% %%% @type target_name() = var_name(). The name of a target. %%% %%% @type handle() = ct_gen_conn:handle() | term(). The identity of a %%% specific connection. -module(ct). %% Command line user interface for running tests -export([install/1, run/1, run/2, run/3, run_test/1, run_testspec/1, step/3, step/4, start_interactive/0, stop_interactive/0]). %% Test suite API -export([require/1, require/2, get_config/1, get_config/2, get_config/3, reload_config/1, log/1, log/2, log/3, print/1, print/2, print/3, pal/1, pal/2, pal/3, fail/1, comment/1, testcases/2, userdata/2, userdata/3]). %% New API for manipulating with config handlers -export([add_config/2, remove_config/2]). %% Other interface functions -export([get_status/0, abort_current_testcase/1, encrypt_config_file/2, encrypt_config_file/3, decrypt_config_file/2, decrypt_config_file/3]). -export([get_target_name/1]). -export([parse_table/1, listenv/1]). %%%----------------------------------------------------------------- %%% @spec install(Opts) -> ok | {error,Reason} %%% Opts = [Opt] %%% Opt = {config,ConfigFiles} | {event_handler,Modules} | %%% {decrypt,KeyOrFile} %%% ConfigFiles = [ConfigFile] %%% ConfigFile = string() %%% Modules = [atom()] %%% KeyOrFile = {key,Key} | {file,KeyFile} %%% Key = string() %%% KeyFile = string() %%% @doc Install config files and event handlers. %%% %%%

Run this function once before first test.

%%% %%%

Example:
%%% install([{config,["config_node.ctc","config_user.ctc"]}]).

%%% %%%

Note that this function is automatically run by the %%% run_test script.

Requires that ct:install/1 has been run first.

%%% %%%

Suites (*_SUITE.erl) files must be stored in %%% TestDir or TestDir/test. All suites %%% will be compiled when test is run.

Note also that the option testcase %%% corresponds to the -case option in the run_test %%% script. Configuration files specified in Opts will be %%% installed automatically at startup. run_test(Opts) -> ct_run:run_test(Opts). %%%----------------------------------------------------------------- %%% @spec run_testspec(TestSpec) -> Result %%% TestSpec = [term()] %%% @doc Run test specified by TestSpec. The terms are %%% the same as those used in test specification files. run_testspec(TestSpec) -> ct_run:run_testspec(TestSpec). %%%----------------------------------------------------------------- %%% @spec step(TestDir,Suite,Case) -> Result %%% Case = atom() %%% %%% @doc Step through a test case with the debugger. %%% @see run/3 step(TestDir,Suite,Case) -> ct_run:step(TestDir,Suite,Case). %%%----------------------------------------------------------------- %%% @spec step(TestDir,Suite,Case,Opts) -> Result %%% Case = atom() %%% Opts = [Opt] | [] %%% Opt = config | keep_inactive %%% %%% @doc Step through a test case with the debugger.

From this mode all test case support functions can be executed %%% directly from the erlang shell. The interactive mode can also be %%% started from the unix command line with run_test -shell %%% [-config File...].

%%% %%%

If any functions using "required config data" (e.g. telnet or %%% ftp functions) are to be called from the erlang shell, config data %%% must first be required with ct:require/2.

%%% %%%

Example:
%%% > ct:require(unix_telnet, unix).
%%% ok
%%% > ct_telnet:open(unix_telnet).
%%% {ok,<0.105.0>}
%%% > ct_telnet:cmd(unix_telnet, "ls .").
%%% {ok,["ls","file1 ...",...]}

start_interactive() -> ct_util:start(interactive). %%%----------------------------------------------------------------- %%% @spec stop_interactive() -> ok %%% %%% @doc Exit the interactive mode. %%% @see start_interactive/0 stop_interactive() -> ct_util:stop(normal). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% MISC INTERFACE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%----------------------------------------------------------------- %%% @spec require(Required) -> ok | {error,Reason} %%% Required = Key | {Key,SubKeys} %%% Key = atom() %%% SubKeys = SubKey | [SubKey] %%% SubKey = atom() %%% %%% @doc Check if the required configuration is available. %%% %%%

Example: require the variable myvar:
%%% ok = ct:require(myvar)

%%% %%%

In this case the config file must at least contain:

%%%
%%% {myvar,Value}.
%%% %%%

Example: require the variable myvar with %%% subvariable sub1:
%%% ok = ct:require({myvar,sub1})

%%% %%%

In this case the config file must at least contain:

%%%
%%% {myvar,[{sub1,Value}]}.
%%% %%% @see require/2 %%% @see get_config/1 %%% @see get_config/2 %%% @see get_config/3 require(Required) -> ct_config:require(Required). %%%----------------------------------------------------------------- %%% @spec require(Name,Required) -> ok | {error,Reason} %%% Name = atom() %%% Required = Key | {Key,SubKeys} %%% Key = atom() %%% SubKeys = SubKey | [SubKey] %%% SubKey = atom() %%% %%% @doc Check if the required configuration is available, and give it %%% a name. %%% %%%

If the requested data is available, the main entry will be %%% associated with Name so that the value of the element %%% can be read with get_config/1,2 provided %%% Name instead of the Key.

%%% %%%

Example: Require one node with a telnet connection and an %%% ftp connection. Name the node a:
ok = %%% ct:require(a,{node,[telnet,ftp]}).
All references %%% to this node may then use the node name. E.g. you can fetch a %%% file over ftp like this:
%%% ok = ct:ftp_get(a,RemoteFile,LocalFile).

%%% %%%

For this to work, the config file must at least contain:

%%%
%%% {node,[{telnet,IpAddr},
%%%        {ftp,IpAddr}]}.
%%% %%% @see require/1 %%% @see get_config/1 %%% @see get_config/2 %%% @see get_config/3 require(Name,Required) -> ct_config:require(Name,Required). %%%----------------------------------------------------------------- %%% @spec get_config(Required) -> Value %%% @equiv get_config(Required,undefined,[]) get_config(Required) -> ct_config:get_config(Required,undefined,[]). %%%----------------------------------------------------------------- %%% @spec get_config(Required,Default) -> Value %%% @equiv get_config(Required,Default,[]) get_config(Required,Default) -> ct_config:get_config(Required,Default,[]). %%%----------------------------------------------------------------- %%% @spec get_config(Required,Default,Opts) -> ValueOrElement %%% Required = KeyOrName | {KeyOrName,SubKey} %%% KeyOrName = atom() %%% SubKey = atom() %%% Default = term() %%% Opts = [Opt] | [] %%% Opt = element | all %%% ValueOrElement = term() | Default %%% %%% @doc Read config data values. %%% %%%

This function returns the matching value(s) or config element(s), %%% given a config variable key or its associated name %%% (if one has been specified with require/2 or a %%% require statement).

%%% %%%

Example, given the following config file:

%%%
%%% {unix,[{telnet,IpAddr},
%%%        {username,Username},
%%%        {password,Password}]}.
%%%

get_config(unix,Default) -> %%% [{telnet,IpAddr}, %%% {username,Username}, %%% {password,Password}]
%%% get_config({unix,telnet},Default) -> IpAddr
%%% get_config({unix,ftp},Default) -> Default
%%% get_config(unknownkey,Default) -> Default

%%% %%%

If a config variable key has been associated with a name (by %%% means of require/2 or a require statement), the name %%% may be used instead of the key to read the value:

%%% %%%

require(myhost,unix) -> ok
%%% get_config(myhost,Default) -> %%% [{telnet,IpAddr}, %%% {username,Username}, %%% {password,Password}]

%%% %%%

If a config variable is defined in multiple files and you want to %%% access all possible values, use the all option. The %%% values will be returned in a list and the order of the elements %%% corresponds to the order that the config files were specified at %%% startup.

%%% %%%

If you want config elements (key-value tuples) returned as result %%% instead of values, use the element option. %%% The returned elements will then be on the form {KeyOrName,Value}, %%% or (in case a subkey has been specified) %%% {{KeyOrName,SubKey},Value}

%%% %%% @see get_config/1 %%% @see get_config/2 %%% @see require/1 %%% @see require/2 get_config(Required,Default,Opts) -> ct_config:get_config(Required,Default,Opts). %%%----------------------------------------------------------------- %%% @spec reload_config(Required) -> ValueOrElement %%% Required = KeyOrName | {KeyOrName,SubKey} %%% KeyOrName = atom() %%% SubKey = atom() %%% ValueOrElement = term() %%% %%% @doc Reload config file which contains specified configuration key. %%% %%%

This function performs updating of the configuration data from which the %%% given configuration variable was read, and returns the (possibly) new %%% value of this variable.

%%% reload_config(Required)-> ct_config:reload_config(Required). %%%----------------------------------------------------------------- %%% @spec log(Format) -> ok %%% @equiv log(default,Format,[]) log(Format) -> log(default,Format,[]). %%%----------------------------------------------------------------- %%% @spec log(X1,X2) -> ok %%% X1 = Category | Format %%% X2 = Format | Args %%% @equiv log(Category,Format,Args) log(X1,X2) -> {Category,Format,Args} = if is_atom(X1) -> {X1,X2,[]}; is_list(X1) -> {default,X1,X2} end, log(Category,Format,Args). %%%----------------------------------------------------------------- %%% @spec log(Category,Format,Args) -> ok %%% Category = atom() %%% Format = string() %%% Args = list() %%% %%% @doc Printout from a testcase to the log. %%% %%%
