Remove test_server as a standalone application
The test_server application has previously been deprecated.
In OTP 19, we will move relevant parts of test_server into the
common_test application. Test suites that include test_server.hrl
must be updated to include ct.hrl instead. Test suites that include
test_server_line.hrl must removed that inclusion. Test suites that
call the test_server module directly will continue to work in OTP 19.
The test suites for Erlang/OTP are built and executed in exactly
the same way as previously.
Here are some more details.
The modules test_server*.erl and erl2html2.erl in lib/test_server/src
have been moved to common_test/src.
The test_server.hrl and test_server_line.hrl include files have
been deleted. The macros in test_server.hrl have been copied into
lib/common_test/include/ct.hrl.
The ts*.erl modules and their associated data files in
lib/test_server/src has been been moved to the new directory
lib/common_test/test_server. The ts* modules are no longer built
to lib/common_test/ebin. They will only built when 'make release_tests'
is executed.
The test suite for test_server has been moved to lib/common_test/test.
The rest of the files have been deleted.

It provides an - interface for running test programs directly with Test Server - as well as an interface for integrating Test Server - with a framework application. The latter makes it possible to use - Test Server as the engine of a higher level test tool - application.</p> - - <p>It is strongly recommended that Test Server be used from inside - a framework application, rather than interfaced directly for - running test programs. Test Server can be pretty difficult to use - since it's a very general and quite extensive and complex - application. Furthermore, the <c>test_server_ctrl</c> functions - are not meant to be used from within the actual test programs. The - framework should handle communication with Test Server and deal - with the more complex aspects of this interaction automatically so - that a higher level interface may be provided for the tester. For - test tool usage to be productive, a simpler, more intuitive and - (if required) more specific interface is required than what Test Server - can provide.</p> - - <p>OTP delivers a general purpose framework for Test Server, called - <em>Common Test</em>. This application is a tool well suited for - automated black box testing of target systems of <em>any kind</em> - (not necessarily implemented in Erlang). Common Test is also a very - useful tool for white box testing of Erlang programs and OTP - applications. Unless a more specific functionality and/or user - interface is required (in which case you might need to implement - your own framework), Common Test should do the job for - you. Please read the Common Test User's Guide and reference manual - for more information.</p> - - <p>Under normal circumstances, knowledge about the Test Server - application is not required for using the Common Test framework. - However, if you want to use Test Server without a framework, - or learn how to integrate it with your own framework, please read on... - </p> - </section> - <section> - <title>Getting started</title> - <p>Testing when using Test Server is done by running test - suites. A test suite is a number of test cases, where each test - case tests one or more things. The test case is the smallest unit - that the test server deals with. One or more test cases are - grouped together into one ordinary Erlang module, which is called - a test suite. Several test suite modules can be grouped together - in special test specification files representing whole application - and/or system test "jobs". - </p> - <p>The test suite Erlang module must follow a certain interface, - which is specified by Test Server. See the section on writing - test suites for details about this. - </p> - <p>Each test case is considered a success if it returns to the - caller, no matter what the returned value is. An exception to this - is the return value <c>{skip, Reason}</c> which indicates that the - test case is skipped. A failure is specified as a crash, no matter - what the crash reason is. - </p> - <p>As a test suite runs, all information (including output to - stdout) is recorded in several different log files. A minimum of - information is displayed to the user console. This only include - start and stop information, plus a note for each failed test case. - </p> - <p>The result from each test case is recorded in an HTML log file - which is created for each test run. Every test case gets one row - in a table presenting total time, whether the case was successful - or not, if it was skipped, and possibly also a comment. The HTML - file has links to each test case's logfile, which may be viewed - from e.g. Netscape or any other HTML capable browser. - </p> - <p>The Test Server consists of three parts: - </p> - <list type="bulleted"> - <item>The part that executes the test suites and - provides support for the test suite author is called - <c>test_server</c>. This is described in the chapter about - writing test cases in this user's guide, and in the reference - manual for the <c>test_server</c> module.</item> - <item>The controlling part, which provides the low level - operator interface, starts and stops slave nodes and writes - log files, is called - <c>test_server_ctrl</c>. The Test Server Controller should not - be used directly when running tests. Instead a framework built - on top of it should be used. More information - about how to write your own framework can be found - in this user's guide and in the reference manual for the - <c>test_server_ctrl</c> module.</item> - </list> - </section> - - <section> - <title>Definition of terms</title> - <taglist> - <tag><em>conf(iguration) case</em></tag> - <item>This is a group of test cases which need some specific - configuration. A conf case contains an initiation function which - sets up a specific configuration, one or more test cases using - this configuration, and a cleanup function which restores the - configuration. A conf case is specified in a test specification - either like this:<c>{conf,InitFunc,ListOfCases,CleanupFunc}</c>, - or this: <c>{conf,Properties,InitFunc,ListOfCases,CleanupFunc}</c> - </item> - <tag><em>datadir</em></tag> - <item>Data directory for a test suite. This directory contains - any files used by the test suite, e.g. additional erlang - modules, c code or data files. If the data directory contains - code which must be compiled before the test suite is run, it - should also contain a makefile source called Makefile.src - defining how to compile. - </item> - <tag><em>documentation clause</em></tag> - <item>One of the function clauses in a test case.

A test specification can - also group several test cases into conf cases with init and - cleanup functions (see section about configuration cases - below). In a test there can be test specifications on three - different levels: - </p> - <p>The top level is a test specification file which roughly - specifies what to test for a whole application. The test - specification in such a file is encapsulated in a topcase - command. - </p> - <p>Then there is a test specification for each test suite, - specifying which test cases to run within the suite. The test - specification for a test suite is returned from the - <c>all(suite)</c> function in the test suite module. - </p> - <p>And finally there can be a test specification per test case, - specifying sub test cases to run.

A conf - case consists of an initialization function, the group of test cases - needing this initialization and a cleanup or finalization function. - </p> - <p>If the init function in a conf case fails or returns - <c>{skip,Comment}</c>, the rest of the test cases in the conf case - (including the cleanup function) are skipped. If the init function - succeeds, the cleanup function will always be called, even if some - of the test cases in between failed. - </p> - <p>Both the init function and the cleanup function in a conf case - get the <c>Config</c> parameter as only argument. This parameter - can be modified or returned as is. Whatever is returned by the - init function is given as <c>Config</c> parameter to the rest of - the test cases in the conf case, including the cleanup function. - </p> - <p>If the <c>Config</c> parameter is changed by the init function, - it must be restored by the cleanup function. Whatever is returned - by the cleanup function will be given to the next test case called. - </p> - <p>The optional <c>Properties</c> list can be used to specify - execution properties for the test cases and possibly nested - sub-groups of the configuration case. The available properties are:</p> - <pre> - Properties = [parallel | sequence | Shuffle | {RepeatType,N}] - Shuffle = shuffle | {shuffle,Seed} - Seed = {integer(),integer(),integer()} - RepeatType = repeat | repeat_until_all_ok | repeat_until_all_fail | - repeat_until_any_ok | repeat_until_any_fail - N = integer() | forever</pre> - - <p>If the <c>parallel</c> property is specified, Test Server will execute - all test cases in the group in parallel. If <c>sequence</c> is specified, - the cases will be executed in a sequence, meaning if one case fails, all - following cases will be skipped. If <c>shuffle</c> is specified, the cases - in the group will be executed in random order. The <c>repeat</c> property - orders Test Server to repeat execution of the cases in the group a given - number of times, or until any, or all, cases fail or succeed.</p> - - <p>Properties may be combined so that e.g. if <c>shuffle</c>, - <c>repeat_until_any_fail</c> and <c>sequence</c> are all specified, the test - cases in the group will be executed repeatedly and in random order until - a test case fails, when execution is immediately stopped and the rest of - the cases skipped.</p> - - <p>The properties for a conf case is always printed on the top of the HTML log - for the group's init function. Also, the total execution time for a conf case - can be found at the bottom of the log for the group's end function.</p> - - <p>Configuration cases may be nested so that sets of grouped cases can be - configured with the same init- and end functions.</p> - </section> - - <section> - <title>The parallel property and nested configuration cases</title> - <p>If a conf case has a parallel property, its test cases will be spawned - simultaneously and get executed in parallel. A test case is not allowed - to execute in parallel with the end function however, which means - that the time it takes to execute a set of parallel cases is equal to the - execution time of the slowest test case in the group. A negative side - effect of running test cases in parallel is that the HTML summary pages - are not updated with links to the individual test case logs until the - end function for the conf case has finished.</p> - - <p>A conf case nested under a parallel conf case will start executing in - parallel with previous (parallel) test cases (no matter what properties the - nested conf case has). Since, however, test cases are never executed in - parallel with the init- or the end function of the same conf case, it's - only after a nested group of cases has finished that any remaining parallel - cases in the previous conf case get spawned.</p> - </section> - - <section> - <title>Repeated execution of test cases</title> - <marker id="repeated_cases"></marker> - <p>A conf case may be repeated a certain number of times - (specified by an integer) or indefinitely (specified by <c>forever</c>). - The repetition may also be stopped prematurely if any or all cases - fail or succeed, i.e. if the property <c>repeat_until_any_fail</c>, - <c>repeat_until_any_ok</c>, <c>repeat_until_all_fail</c>, or - <c>repeat_until_all_ok</c> is used. If the basic <c>repeat</c> - property is used, status of test cases is irrelevant for the repeat - operation.</p> - - <p>It is possible to return the status of a conf case (ok or - failed), to affect the execution of the conf case on the level above. - This is accomplished by, in the end function, looking up the value - of <c>tc_group_properties</c> in the <c>Config</c> list and checking the - result of the finished test cases. If status <c>failed</c> should be - returned from the conf case as a result, the end function should return - the value <c>{return_group_result,failed}</c>. The status of a nested conf - case is taken into account by Test Server when deciding if execution - should be repeated or not (unless the basic <c>repeat</c> property is used).</p> - - <p>The <c>tc_group_properties</c> value is a list of status tuples, - each with the key <c>ok</c>, <c>skipped</c> and <c>failed</c>. The - value of a status tuple is a list containing names of test cases - that have been executed with the corresponding status as result.</p> - - <p>Here's an example of how to return the status from a conf case:</p> - <pre> - conf_end_function(Config) -> - Status = ?config(tc_group_result, Config), - case proplists:get_value(failed, Status) of - [] -> % no failed cases - {return_group_result,ok}; - _Failed -> % one or more failed - {return_group_result,failed} - end.</pre> - - <p>It is also possible in the end function to check the status of - a nested conf case (maybe to determine what status the current conf case should - return). This is as simple as illustrated in the example above, only the - name of the end function of the nested conf case is stored in a tuple - <c>{group_result,EndFunc}</c>, which can be searched for in the status lists. - Example:</p> - <pre> - conf_end_function_X(Config) -> - Status = ?config(tc_group_result, Config), - Failed = proplists:get_value(failed, Status), - case lists:member({group_result,conf_end_function_Y}, Failed) of - true -> - {return_group_result,failed}; - false -> - {return_group_result,ok} - end; - ...</pre> - - <note><p>When a conf case is repeated, the init- and end functions - are also always called with each repetition.</p></note> - </section> - - <section> - <title>Shuffled test case order</title> - <p>The order that test cases in a conf case are executed, is under normal - circumstances the same as the order defined in the test specification. - With the <c>shuffle</c> property set, however, Test Server will instead - execute the test cases in random order.</p> - - <p>The user may provide a seed value (a tuple of three integers) with - the shuffle property: <c>{shuffle,Seed}</c>. This way, the same shuffling - order can be created every time the conf case is executed. If no seed value - is given, Test Server creates a "random" seed for the shuffling operation - (using the return value of <c>erlang:now()</c>). The seed value is always - printed to the log file of the init function so that it can be used to - recreate the same execution order in subsequent test runs.</p> - - <note><p>If execution of a conf case with shuffled test cases is repeated, - the seed will not be reset in between turns.</p></note> - - <p>If a nested conf case is specified in a conf case with a <c>shuffle</c> - property, the execution order of the nested cases in relation to the test cases - (and other conf cases) is also random. The order of the test cases in the nested - conf case is however not random (unless, of course, this one also has a - <c>shuffle</c> property).</p> - </section> - - <section> - <title>Skipping test cases</title> - <p>It is possible to skip certain test cases, for example if you - know beforehand that a specific test case fails. This might be - functionality which isn't yet implemented, a bug that is known but - not yet fixed or some functionality which doesn't work or isn't - applicable on a specific platform. - </p> - <p>There are several different ways to state that a test case - should be skipped:</p> - <list type="bulleted"> - <item>Using the <c>{skip,What}</c> command in a test - specification file - </item> - <item>Returning <c>{skip,Reason}</c> from the - <c>init_per_testcase/2</c> function - </item> - <item>Returning <c>{skip,Reason}</c> from the specification - clause of the test case - </item> - <item>Returning <c>{skip,Reason}</c> from the execution clause - of the test case - </item> - </list> - <p>The latter of course means that the execution clause is - actually called, so the author must make sure that the test case - is not run.

On the contrary, it has been formally proven that it is - impossible to prove programs in general by testing. Theoretical - program proofs or plain examination of code may be viable options - for those that wish to certify that a program is correct. The test - server, as it is based on testing, cannot be used for - certification. Its intended use is instead to (cost effectively) - <em>find bugs</em>. A successful test suite is one that reveals a - bug. If a test suite results in Ok, then we know very little that - we didn't know before. - </p> - </section> - - <section> - <title>What to test?</title> - <p>There are many kinds of test suites. Some concentrate on - calling every function in the interface to some module or - server. Some other do the same, but uses all kinds of illegal - parameters, and verifies that the server stays alive and rejects - the requests with reasonable error codes. Some test suites - simulate an application (typically consisting of a few modules of - an application), some try to do tricky requests in general, some - test suites even test internal functions. - </p> - <p>Another interesting category of test suites are the ones that - check that fixed bugs don't reoccur. When a bugfix is introduced, - a test case that checks for that specific bug should be written - and submitted to the affected test suite(s). - </p> - <p>Aim for finding bugs. Write whatever test that has the highest - probability of finding a bug, now or in the future. Concentrate - more on the critical parts. Bugs in critical subsystems are a lot - more expensive than others. - </p> - <p>Aim for functionality testing rather than implementation - details. Implementation details change quite often, and the test - suites should be long lived. Often implementation details differ - on different platforms and versions. If implementation details - have to be tested, try to factor them out into separate test - cases. Later on these test cases may be rewritten, or just - skipped. - </p> - <p>Also, aim for testing everything once, no less, no more. It's - not effective having every test case fail just because one - function in the interface changed. - </p> - </section> - - <section> - <title>How much to test</title> - <p>There is a unix shell script that counts the number of non - commented words (lines and characters too) of source code in each - application's test directory and divides with the number of such - source words in the src directory. This is a measure of how much - test code there is. - </p> - <p>There has been much debate over how much test code, compared to - production code, should be written in a project. More test code - finds more bugs, but test code needs to be maintained just like - the production code, and it's expensive to write it in the first - place. In several articles from relatively mature software - organizations that I have read, the amount of test code has been - about the same as the production code. </p> - <p>In OTP, at the time of - writing, few applications come even close to this, some have no - test code at all. - </p> - - <section> - <title>Full coverage</title> - <p>It is possible to cover compile the modules being tested - before running the test suites. Doing so displays which branches - of the code that are tested by the test suite, and which are - not. Many use this as a measure of a good test suite. When every - single line of source code is covered once by the test suite, - the test suite is finished. - </p> - <p>A coverage of 100% still proves nothing, though. It doesn't - mean that the code is error free, that everything is tested. For - instance, if a function contains a division, it has to be - executed at least twice. Once with parameters that cause - division by zero, and once with other parameters. - </p> - <p>High degree of coverage is good of course, it means that no - major parts of the code has been left untested. It's another - question whether it's cost effective. You're only likely to find - 50% more bugs when going from 67% to 100% coverage, but the work - (cost) is maybe 200% as large, or more, because reaching all of - those obscure branches is usually complicated. - </p> - <p>Again, the reason for testing with the test server is to find - bugs, not to create certificates of valid code. Maximizing the - number of found bugs per hour probably means not going for 100% - coverage. For some module the optimum may be 70%, for some other - maybe 250%. 100% shouldn't be a goal in itself.</p> - </section> - - <section> - <title>User interface testing</title> - <p>It is very difficult to do sensible testing of user - interfaces, especially the graphic ones. The test server has - some support for capturing the text I/O that goes to the user, - but none for graphics.

Please see the chapter - about test specifications for details about this. - </p> - </section> - - <section> - <title>Init per test case</title> - <p>In each test suite module, the functions - <c>init_per_testcase/2</c> and <c>end_per_testcase/2</c> must be - implemented. - </p> - <p><c>init_per_testcase</c> is called before each test case in the - test suite, giving a (limited) possibility for initialization. - </p> - <p><c>end_per_testcase/2</c> is called after each test case is - completed, giving a possibility to clean up. - </p> - <p>The first argument to these functions is the name of the test - case. This can be used to do individual initialization and cleanup for - each test cases. - </p> - <p>The second argument is a list of tuples called - <c>Config</c>. The first element in a <c>Config</c> tuple - should be an atom - a key value to be used for searching. - <c>init_per_testcase/2</c> may modify the <c>Config</c> - parameter or just return it as is. Whatever is retuned by - <c>init_per_testcase/2</c> is given as <c>Config</c> parameter to - the test case itself. - </p> - <p>The return value of <c>end_per_testcase/2</c> is ignored by the - test server. - </p> - </section> - - <section> - <title>Test cases</title> - <p>The smallest unit that the test server is concerned with is a - test case. Each test case can in turn test many things, for - example make several calls to the same interface function with - different parameters. - </p> - <p>It is possible to put many or few tests into each test - case. How many things each test case tests is up to the author, - but here are some things to keep in mind. - </p> - <p>Very small test cases often leads to more code, since - initialization has to be duplicated. Larger code, especially with - a lot of duplication, increases maintenance and reduces - readability. - </p> - <p>Larger test cases make it harder to tell what went wrong if it - fails, and force us to skip larger portions of test code if a - specific part fails. These effects are accentuated when running on - multiple platforms because test cases often have to be skipped. - </p> - <p>A test case generally consists of three parts, the - documentation part, the specification part and the execution - part. These are implemented as three clauses of the same function. - </p> - <p>The documentation clause matches the argument '<c>doc</c>' and - returns a list for strings describing what the test case tests. - </p> - <p>The specification clause matches the argument '<c>suite</c>' - and returns the test specification for this particular test - case. If the test specification is an empty list, this indicates - that the test case is a leaf test case, i.e. one to be executed. - </p> - <p>The execution clause implements the actual test case. It takes - one argument, <c>Config</c>, which contain configuration - information like <c>data_dir</c> and <c>priv_dir</c>. See <seealso marker="#data_priv_dir">Data and Private Directories</seealso> for - more information about these. - </p> - <p>The <c>Config</c> variable can also contain the - <c>nodenames</c> key, if requested by the <c>require_nodenames</c> - command in the test suite specification file. All <c>Config</c> - items should be extracted using the <c>?config</c> macro. This is - to ensure future compatibility if the <c>Config</c> format - changes. See the reference manual for <c>test_server</c> for - details about this macro. - </p> - <p>If the execution clause crashes or exits, it is considered a - failure. If it returns <c>{skip,Reason}</c>, the test case is - considered skipped. If it returns <c>{comment,String}</c>, - the string will be added in the 'Comment' field on the HTML - result page. If the execution clause returns anything else, it is - considered a success, unless it is <c>{'EXIT',Reason}</c> or - <c>{'EXIT',Pid,Reason}</c> which can't be distinguished from a - crash, and thus will be considered a failure. - </p> - </section> - - <section> - <marker id="data_priv_dir"></marker> - <title>Data and Private Directories</title> - <p>The data directory (<c>data_dir</c>) is the directory where the test - module has its own files needed for the testing. A compiler test - case may have source files to feed into the compiler, a release - upgrade test case may have some old and new release of - something. A graphics test case may have some icons and a test - case doing a lot of math with bignums might store the correct - answers there. The name of the <c>data_dir</c> is the the name of - the test suite and then "_data". For example, - <c>"some_path/foo_SUITE.beam"</c> has the data directory - <c>"some_path/foo_SUITE_data/"</c>. - </p> - <p>The <c>priv_dir</c> is the test suite's private directory. This - directory should be used when a test case needs to write to - files. The name of the private directory is generated by the test - server, which also creates the directory. - </p> - <p><em>Warning:</em> Do not depend on current directory to be - writable, or to point to anything in particular. All scratch files - are to be written in the <c>priv_dir</c>, and all data files found - in <c>data_dir</c>. If the current directory has to be something - specific, it must be set with <c>file:set_cwd/1</c>. - </p> - </section> - - <section> - <title>Execution environment</title> - <p>Each time a test case is about to be executed, a new process is - created with <c>spawn_link</c>. This is so that the test case will - have no dependencies to earlier tests, with respect to process flags, - process links, messages in the queue, other processes having registered - the process, etc. As little as possible is done to change the initial - context of the process (what is created by plain spawn). Here is a - list of differences: - </p> - <list type="bulleted"> - <item>It has a link to the test server. If this link is removed, - the test server will not know when the test case is finished, - just wait infinitely. - </item> - <item>It often holds a few items in the process dictionary, all - with names starting with '<c>test_server_</c>'. This is to keep - track of if/where a test case fails. - </item> - <item>There is a top-level catch. All of the test case code is - catched, so that the location of a crash can be reported back to - the test server. If the test case process is killed by another - process (thus the catch code is never executed) the test server - is not able to tell where the test case was executing. - </item> - <item>It has a special group leader implemented by the test - server. This way the test server is able to capture the io that - the test case provokes. This is also used by some of the test - server support functions. - </item> - </list> - <p>There is no time limit for a test case, unless the test case - itself imposes such a limit, by calling - <c>test_server:timetrap/1</c> for example. The call can be made - in each test case, or in the <c>init_per_testcase/2</c> - function. Make sure to call the corresponding - <c>test_server:timetrap_cancel/1</c> function as well, e.g in the - <c>end_per_testcase/2</c> function, or else the test cases will - always fail. - </p> - </section> - -</chapter> - |
