avoid hard coding data values related to the test and/or SUT (System Under Test) in the test suites, the data may instead be specified by means of configuration files or strings that Common Test reads before the start of a test run. External configuration data makes it possible to change test properties without having to modify the actual test suites using the data. Examples of configuration data:</p> <ul> <li>Addresses to the test plant or other instruments</li> <li>User login information</li> <li>Names of files needed by the test</li> <li>Names of programs that should be executed during the test</li> <li>Any other variable needed by the test</li> </ul> <h3><a name="id77671">8.2 Syntax</a></h3> <p>A configuration file can contain any number of elements of the type:</p> <div class="example"><pre> {CfgVarName,Value}.</pre></div> <p>where</p> <div class="example"><pre> CfgVarName = atom() Value = term() | [{CfgVarName,Value}]</pre></div> <h3><a name="id77695">8.3 Requiring and reading configuration data</a></h3> <a name="require_config_data"></a> <p>In a test suite, one must <strong>require</strong> that a configuration variable (<span class="code">CfgVarName</span> in the definition above) exists before attempting to read the associated value in a test case or config function.</p> <p><span class="code">require</span> is an assert statement that can be part of the <span class="bold_code"><a href="write_test_chapter.html#suite">test suite info function</a></span> or <span class="bold_code"><a href="write_test_chapter.html#info_function">test case info function</a></span>. If the required variable is not available, the test is skipped (unless a default value has been specified, see the <span class="bold_code"><a href="write_test_chapter.html#info_function">test case info function</a></span> chapter for details). There is also a function <span class="code"><span class="bold_code"><a href="ct.html#require-1">ct:require/1/2</a></span></span> which can be called from a test case in order to check if a specific variable is available. The return value from this function must be checked explicitly and appropriate action be taken depending on the result (e.g. to skip the test case if the variable in question doesn't exist).</p> <p>A <span class="code">require</span> statement in the test suite info- or test case info-list should look like this: <span class="code">{require,CfgVarName}</span> or <span class="code">{require,AliasName,CfgVarName}</span>. The arguments <span class="code">AliasName</span> and <span class="code">CfgVarName</span> are the same as the arguments to <span class="code"><span class="bold_code"><a href="ct.html#require-1">ct:require/1/2</a></span></span> which are described in the reference manual for <span class="bold_code"><a href="ct.html">ct</a></span>. <span class="code">AliasName</span> becomes an alias for the configuration variable, and can be used as reference to the configuration data value. The configuration variable may be associated with an arbitrary number of alias names, but each name must be unique within the same test suite. There are two main uses for alias names:</p> <ul> <li>They may be introduced to identify connections (see below).</li> <li>They may used to help adapt configuration data to a test suite (or test case) and improve readability.</li> </ul> <p>To read the value of a config variable, use the function <span class="code"><span class="bold_code"><a href="ct.html#get_config-1">get_config/1/2/3</a></span></span> which is also described in the reference manual for <span class="bold_code"><a href="ct.html">ct</a></span>.</p> <p>Example:</p> <div class="example"><pre> suite() -> [{require, domain, 'CONN_SPEC_DNS_SUFFIX'}]. ... testcase(Config) -> Domain = ct:get_config(domain), ...</pre></div> <h3><a name="id77839">8.4 Using configuration variables defined in multiple files</a></h3> <p>If a configuration variable is defined in multiple files and you want to access all possible values, you may use the <span class="code"><span class="bold_code"><a href="ct.html#get_config-3">ct:get_config/3</a></span></span> function and specify <span class="code">all</span> in the options list. The values will then be returned in a list and the order of the elements corresponds to the order that the config files were specified at startup. Please see the <span class="bold_code"><a href="ct.html">ct</a></span> reference manual for details.</p> <h3><a name="id77870">8.5 Encrypted configuration files</a></h3> <a name="encrypted_config_files"></a> <p>It is possible to encrypt configuration files containing sensitive data if these files must be stored in open and shared directories.</p> <p>Call <span class="code"><span class="bold_code"><a href="ct.html#encrypt_config_file-2">ct:encrypt_config_file/2/3</a></span></span> to have Common Test encrypt a specified file using the DES3 function in the OTP <span class="code">crypto</span> application. The encrypted file can then be used as a regular configuration file, in combination with other encrypted files or normal text files. The key for decrypting the configuration file must be provided when running the test, however. This can be done by means of the <span class="code">decrypt_key</span> or <span class="code">decrypt_file</span> flag/option, or a key file in a predefined location.</p> <p>Common Test also provides decryption functions, <span class="code"><span class="bold_code"><a href="ct.html#decrypt_config_file-2">ct:decrypt_config_file/2/3</a></span></span>, for recreating the original text files.</p> <p>Please see the <span class="bold_code"><a href="ct.html">ct</a></span> reference manual for more information.</p> <h3><a name="id77934">8.6 Opening connections by using configuration data</a></h3> <p>There are two different methods for opening a connection by means of the support functions in e.g. <span class="code"><span class="bold_code"><a href="ct_ssh.html">ct_ssh</a></span></span>, <span class="code"><span class="bold_code"><a href="ct_ftp.html">ct_ftp</a></span></span>, and <span class="code"><span class="bold_code"><a href="ct_telnet.html">ct_telnet</a></span></span>:</p> <ul> <li>Using a configuration target name (an alias) as reference.</li> <li>Using the configuration variable as reference.</li> </ul> <p>When a target name is used for referencing the configuration data (that specifies the connection to be opened), the same name may be used as connection identity in all subsequent calls related to the connection (also for closing it). It's only possible to have one open connection per target name. If attempting to open a new connection using a name already associated with an open connection, Common Test will return the already existing handle so that the previously opened connection will be used. This is a practical feature since it makes it possible to call the function for opening a particular connection whenever useful. An action like this will not necessarily open any new connections unless it's required (which could be the case if e.g. the previous connection has been closed unexpectedly by the server). Another benefit of using named connections is that it's not necessary to pass handle references around in the suite for these connections. </p> <p>When a configuration variable name is used as reference to the data specifying the connection, the handle returned as a result of opening the connection must be used in all subsequent calls (also for closing the connection). Repeated calls to the open function with the same variable name as reference will result in multiple connections being opened. This can be useful e.g. if a test case needs to open multiple connections to the same server on the target node (using the same configuration data for each connection). </p> <h3><a name="id78002">8.7 User specific configuration data formats</a></h3> <p>It is possible for the user to specify configuration data on a different format than key-value tuples in a text file, as described so far. The data can e.g. be read from arbitrary files, fetched from the web over http, or requested from a user specific process. To support this, Common Test provides a callback module plugin mechanism to handle configuration data.</p> <h4>Default callback modules for handling configuration data</h4> <p>The Common Test application includes default callback modules for handling configuration data specified in standard config files (see above) and in xml files:</p> <ul> <li> <span class="code">ct_config_plain</span> - for reading configuration files with key-value tuples (standard format). This handler will be used to parse configuration files if no user callback is specified. </li> <li> <span class="code">ct_config_xml</span> - for reading configuration data from XML files. </li> </ul> <h4>Using XML configuration files</h4> <p>This is an example of an XML configuration file:</p> <div class="example"><pre> <config> <ftp_host> <ftp>"targethost"</ftp> <username>"tester"</username> <password>"letmein"</password> </ftp_host> <lm_directory>"/test/loadmodules"</lm_directory> </config></pre></div> <p>This configuration file, once read, will produce the same configuration variables as the following text file:</p> <div class="example"><pre> {ftp_host, [{ftp,"targethost"}, {username,"tester"}, {password,"letmein"}]}. {lm_directory, "/test/loadmodules"}.</pre></div> <h4>How to implement a user specific handler</h4> <p>The user specific handler can be written to handle special configuration file formats. The parameter can be either file name(s) or configuration string(s) (the empty list is valid).</p> <p>The callback module implementing the handler is responsible for checking correctness of configuration strings.</p> <p>To perform validation of the configuration strings, the callback module should have the following function exported:</p> <p><span class="code">Callback:check_parameter/1</span></p> <p>The input argument will be passed from Common Test, as defined in the test specification or given as an option to <span class="code">ct_run</span> or <span class="code">ct:run_test</span>.</p> <p>The return value should be any of the following values indicating if given configuration parameter is valid:</p> <ul> <li> <span class="code">{ok, {file, FileName}}</span> - parameter is a file name and the file exists, </li> <li> <span class="code">{ok, {config, ConfigString}}</span> - parameter is a config string and it is correct, </li> <li> <span class="code">{error, {nofile, FileName}}</span> - there is no file with the given name in the current directory, </li> <li> <span class="code">{error, {wrong_config, ConfigString}}</span> - the configuration string is wrong. </li> </ul> <p>To perform reading of configuration data - initially before the tests start, or as a result of data being reloaded during test execution - the following function should be exported from the callback module:</p> <p><span class="code">Callback:read_config/1</span></p> <p>The input argument is the same as for the <span class="code">check_parameter/1</span> function.</p> <p>The return value should be either:</p> <ul> <li> <span class="code">{ok, Config}</span> - if the configuration variables are read successfully, </li> <li> <span class="code">{error, {Error, ErrorDetails}}</span> - if the callback module fails to proceed with the given configuration parameters. </li> </ul> <p><span class="code">Config</span> is the proper Erlang key-value list, with possible key-value sublists as values, like for the configuration file example above:</p> <div class="example"><pre> [{ftp_host, [{ftp, "targethost"}, {username, "tester"}, {password, "letmein"}]}, {lm_directory, "/test/loadmodules"}]</pre></div> <h3><a name="id78216">8.8 Examples of configuration data handling</a></h3> <p>A config file for using the FTP client to access files on a remote host could look like this:</p> <div class="example"><pre> {ftp_host, [{ftp,"targethost"}, {username,"tester"}, {password,"letmein"}]}. {lm_directory, "/test/loadmodules"}.</pre></div> <p>The XML version shown in the chapter above can also be used, but it should be explicitly specified that the <span class="code">ct_config_xml</span> callback module is to be used by Common Test.</p> <p>Example of how to assert that the configuration data is available and use it for an FTP session:</p> <div class="example"><pre> init_per_testcase(ftptest, Config) -> {ok,_} = ct_ftp:open(ftp), Config. end_per_testcase(ftptest, _Config) -> ct_ftp:close(ftp). ftptest() -> [{require,ftp,ftp_host}, {require,lm_directory}]. ftptest(Config) -> Remote = filename:join(ct:get_config(lm_directory), "loadmodX"), Local = filename:join(?config(priv_dir,Config), "loadmodule"), ok = ct_ftp:recv(ftp, Remote, Local), ...</pre></div> <p>An example of how the above functions could be rewritten if necessary to open multiple connections to the FTP server:</p> <div class="example"><pre> init_per_testcase(ftptest, Config) -> {ok,Handle1} = ct_ftp:open(ftp_host), {ok,Handle2} = ct_ftp:open(ftp_host), [{ftp_handles,[Handle1,Handle2]} | Config]. end_per_testcase(ftptest, Config) -> lists:foreach(fun(Handle) -> ct_ftp:close(Handle) end, ?config(ftp_handles,Config)). ftptest() -> [{require,ftp_host}, {require,lm_directory}]. ftptest(Config) -> Remote = filename:join(ct:get_config(lm_directory), "loadmodX"), Local = filename:join(?config(priv_dir,Config), "loadmodule"), [Handle | MoreHandles] = ?config(ftp_handles,Config), ok = ct_ftp:recv(Handle, Remote, Local), ...</pre></div> <h3><a name="id78268">8.9 Example of user specific configuration handler</a></h3> <p>A simple configuration handling driver which will ask an external server for configuration data can be implemented this way:</p> <div class="example"><pre> -module(config_driver). -export([read_config/1, check_parameter/1]). read_config(ServerName)-> ServerModule = list_to_atom(ServerName), ServerModule:start(), ServerModule:get_config(). check_parameter(ServerName)-> ServerModule = list_to_atom(ServerName), case code:is_loaded(ServerModule) of {file, _}-> {ok, {config, ServerName}}; false-> case code:load_file(ServerModule) of {module, ServerModule}-> {ok, {config, ServerName}}; {error, nofile}-> {error, {wrong_config, "File not found: " ++ ServerName ++ ".beam"}} end end.</pre></div> <p>The configuration string for this driver may be "config_server", if the config_server.erl module below is compiled and exists in the code path during test execution:</p> <div class="example"><pre> -module(config_server). -export([start/0, stop/0, init/1, get_config/0, loop/0]). -define(REGISTERED_NAME, ct_test_config_server). start()-> case whereis(?REGISTERED_NAME) of undefined-> spawn(?MODULE, init, [?REGISTERED_NAME]), wait(); _Pid-> ok end, ?REGISTERED_NAME. init(Name)-> register(Name, self()), loop(). get_config()-> call(self(), get_config). stop()-> call(self(), stop). call(Client, Request)-> case whereis(?REGISTERED_NAME) of undefined-> {error, {not_started, Request}}; Pid-> Pid ! {Client, Request}, receive Reply-> {ok, Reply} after 4000-> {error, {timeout, Request}} end end. loop()-> receive {Pid, stop}-> Pid ! ok; {Pid, get_config}-> {D,T} = erlang:localtime(), Pid ! [{localtime, [{date, D}, {time, T}]}, {node, erlang:node()}, {now, erlang:now()}, {config_server_pid, self()}, {config_server_vsn, ?vsn}], ?MODULE:loop() end. wait()-> case whereis(?REGISTERED_NAME) of undefined-> wait(); _Pid-> ok end.</pre></div> <p>In this example, the handler also provides the ability to dynamically reload configuration variables. If <span class="code">ct:reload_config(localtime)</span> is called from the test case function, all variables loaded with <span class="code">config_driver:read_config/1</span> will be updated with their latest values, and the new value for variable <span class="code">localtime</span> will be returned.</p> </div> <div class="footer"> <hr> <p>Copyright © 2003-2012 Ericsson AB.
