It + * is licensed under a BSD license - read the top of each file. + * + * All the GUI related stuff is in tdesdk/tdeunittest, the core libraries are in tdelibs/tdeunittest. + * A simple example modules is in kdelisbs/tdeunittest/samplemodule.{h,cpp}, however more examples + * can be found in tdesdk/tdeunittest/example. + * + * There are roughly two ways to use the KUnitTest library. Either you create dynamically + * loadable modules and use the tdeunittestmodrunner or tdeunittestguimodrunner programs to run + * the tests, or you use the tdeunittest/tdeunittestgui library to create your own test runner + * application. + * + * The main parts of the KUnitTest library are: + * @li runner.{h,cpp} - it is the tester runner, holds all tests and runs + * them. + * @li runnergui.{h,cpp} - the GUI wrapper around the runner. The GUI neatly organizes the + * test results. With the tdeunittest helper script it can even add the debug output + * to the test results. For this you need to have the tdesdk module installed. + * @li tester.h - which holds the base of a pure test object (Tester). + * @li module.h - defines macros to create a dynamically loadable module. + * + * @section usage Example usage + * + * This section describes how to use the library to create your own tests and runner + * application. + * + * Now lets see how you would add a new test to KUnitTest. You do that by + * writting a Tester derived class which has an "allTests()" method: + * + * @code + * class SampleTest : public Tester + * { + * public: + * SampleTest(); + * + * void allTests(); + * }; + * @endcode + * + * Now in the allTests() method we implement our tests, which might look + * like: + * + * @code + * void SampleTest::allTests() + * { + * CHECK( 3+3, 6 ); + * CHECK( TQString( "hello%1" ).arg( " world not" ), TQString( "hello world" ) ); + * } + * @endcode + * + * CHECK() is implemented using a template, so you get type safe + * comparison. All that is needed is that the argument types have an + * @c operator==() defined. + * + * Now that you did that the only other thing to do is to tell the + * framework to add this test case, by using the KUNITTEST_REGISTER_TESTER(x) macro. Just + * put the following line in the implementation file: + * + * @code KUNITTEST_REGISTER_TESTER( SampleTest ); @endcode + * + * Note the ;, it is necessary. + * + * KUnitTest will do the rest. It will tell you which tests failed, how, what was the expected + * result, what was the result it got, what was the code that failed and so on. For example for + * the code above it would output: + * + * @verbatim +SampleTest - 1 test passed, 1 test failed + Unexpected failure: + sampletest.cpp[38]: failed on "TQString( "hello%1" ).arg( " world not" )" + result = 'hello world not', expected = 'hello world' +@endverbatim + * + * If you use the RunnerGUI class then you will be presented with a scrollable list of the + * test results. + * + * @section integration Integration + * + * The KUnitTest library is easy to use. Let's say that you have the tests written in the + * sampletest.h and sampletest.cpp files. Then all you need is a main.cpp file and a Makefile.am. + * You can copy both from the example file provided with the library. A typical main.cpp file + * looks like this: + * + * @code + * #include <kaboutdata.h> + * #include <kapplication.h> + * #include <kcmdlineargs.h> + * #include <kcmdlineargs.h> + * #include <klocale.h> + * #include <tdeunittest/runnergui.h> + * + * static const char description[] = I18N_NOOP("SampleTests"); + * static const char version[] = "0.1"; + * static KCmdLineOptions options[] = { KCmdLineLastOption }; + * + * int main( int argc, char** argv ) + * { + * TDEAboutData about("SampleTests", I18N_NOOP("SampleTests"), version, description, + * TDEAboutData::License_BSD, "(C) 2005 You!", 0, 0, "mail@provider"); + * + * TDECmdLineArgs::init(argc, argv, &about); + * TDECmdLineArgs::addCmdLineOptions( options ); + * TDEApplication app; + * + * KUnitTest::RunnerGUI runner(0); + * runner.show(); + * app.setMainWidget(&runner); + * + * return app.exec(); + * } + * @endcode + * + * The Makefile.am file will look like: + * + * @code + * INCLUDES = -I$(top_srcdir)/src $(all_includes) + * METASOURCES = AUTO + * check_PROGRAMS = sampletests + * sampletests_SOURCES = main.cpp sampletest.cpp + * sampletests_LDFLAGS = $(KDE_RPATH) $(all_libraries) + * sampletests_LDADD = -ltdeunittest + * noinst_HEADERS = sampletest.h + * + * check: + * tdeunittest $(top_builddir)/src/sampletests SampleTests + * @endcode + * + * Most of this Makefile.am will be self-explanatory. After running + * "make check" the binary "sampletests" will be built. The reason for + * adding the extra make target "check" is that you probably do not want + * to rebuild the test suite everytime you run make. + * + * You can run the binary on its own, but you get more functionality if you use + * the tdeunittest helper script. The Makefile.am is set up in such + * a way that this helper script is automatically run after you do a + * "make check". This scripts take two arguments, the first is the path + * to the binary to run. The second the application name, in this case SampleTests. + * This name is important since it is used to let the script communicate with the application + * via DCOP. The helper scripts relies on the Perl DCOP bindings, so these need to be installed. + * + * @section module Creating test modules + * + * If you think that writing your own test runner if too much work then you can also + * use the tdeunittestermodrunner application or the kunitguimodrunner script to run + * the tests for you. You do have to put your tests in a dynamically loadable module though. + * Fortunately KUnitTest comes with a few macros to help you do this. + * + * First the good news, you don't have to change the header file sampletest.h. However, we + * will rename it to samplemodule.h, so we remember we are making a module. The + * implementation file should be rename to samplemodule.cpp. This file requires some + * modifications. First we need to include the module.h header: + * + * @code + * #include <tdeunittest/module.h> + * @endcode + * + * This header file is needed because it defines some macro you'll need. In fact this is + * how you use them: + * + * @code + * KUNITTEST_MODULE( tdeunittest_samplemodule, "Tests for sample module" ); + * KUNITTEST_MODULE_REGISTER_TESTER( SimpleSampleTester ); + * KUNITTEST_MODULE_REGISTER_TESTER( SomeSampleTester ); + * @endcode + * + * The first macro, KUNITTEST_MODULE(), makes sure that the module can be loaded and that + * the test classes are created. The first argument "tdeunittest_samplemodule" is the library + * name, in this case the library we're creating a tdeunittest_samplemodule.la module. The + * second argument is name which will appear in the test runner for this test suite. + * + * The tester class are now added by the KUNITTEST_MODULE_REGISTER_TESTER() macro, not the + * KUNITTEST_REGISTER_TESTER(). The only difference between the two is that you have to + * pass the module class name to this macro. + * + * The Makefile.am is also a bit different, but not much: + * + * @code + * INCLUDES = -I$(top_srcdir)/include $(all_includes) + * METASOURCES = AUTO + * check_LTLIBRARIES = tdeunittest_samplemodule.la + * tdeunittest_samplemodule_la_SOURCES = samplemodule.cpp + * tdeunittest_samplemodule_la_LIBADD = $(LIB_KUNITTEST) + * tdeunittest_samplemodule_la_LDFLAGS = -module $(KDE_CHECK_PLUGIN) $(all_libraries) + * @endcode + * + * The $(KDE_CHECK_PLUGIN) macro is there to make sure a dynamically loadable + * module is created. + * + * After you have built the module you open a Konsole and cd into the build folder. Running + * the tests in the module is now as easy as: + * + * @code + * $ make check && tdeunittestmodrunner + * @endcode + * + * The tdeunittestmodrunner application loads all tdeunittest_*.la modules in the current + * directory. The exit code of this console application is the number of unexpected failures. + * + * If you want the GUI, you should use the tdeunittestmod script: + * + * @code + * $ make check && tdeunittestmod + * @endcode + * + * This script starts tdeunittestguimodrunner application and a helper script to take + * care of dealing with debug output. + * + * @section advanced Advanced usage + * + * Normally you just want to use CHECK(). If you are developing some more + * tests, and they are run (or not) based on some external dependency, + * you may need to skip some tests. In this case, rather than doing + * nothing (or worse, writing a test step that aborts the test run), you + * might want to use SKIP() to record that. Note that this is just a + * logging / reporting tool, so you just pass in a string: + * + * @code + * SKIP( "Test skipped because of lack of foo support." ); + * @endcode + * + * Similarly, you may have a test step that you know will fail, but you + * don't want to delete the test step (because it is showing a bug), but + * equally you can't fix it right now (eg it would break binary + * compatibility, or would violate a string freeze). In that case, it + * might help to use XFAIL(), for "expected failure". The test will still + * be run, and recorded as a failure (assuming it does fail), but will + * also be recorded separately. Usage might be as follows: + * + * @code + * XFAIL( 2+1, 4 ); + * @endcode + * + * You can mix CHECK(), SKIP() and XFAIL() within a single Tester derived + * class. + * + * + * @section exceptions Exceptions + * + * KUnitTest comes with simple support for testing whether an exception, such as a function call, + * throws an exception or not. Simply, for the usual macros there corresponding ones for + * exception testing: CHECK_EXCEPTION(), XFAIL_EXCEPTION(), and SKIP_EXCEPTION(). They all take two + * arguments: the expression that will catch the exception, and the expression that is supposed + * to throw the exception. + * + * For example: + * + * @code + * CHECK_EXCEPTION(EvilToothFairyException *, myFunction("I forgot to brush my teeth!")); + * @endcode + * + * @note The exception is not de-allocated in anyway. + * + * The macros does not allow introspection of the exceptions, such as testing a supplied + * identifier code on the exception object or similar; this requires manual coding, such + * as custom macros. + * + * @section scripts Scripts + * + * The library comes with several helper scripts: + * + * @li tdeunittest [app] [dcopobject] : Runs the application app and redirects all debug output to the dcopobject. + * @li tdeunittestmod --folder [folder] --query [query] : Loads and runs all modules in the folder matching the query.
