| 16 | * \page unittest "Unit test" | 
|---|
| 17 | * | 
|---|
| 18 | * Unit tests are done via the CppUnit framework (http://cppunit.sourceforge.net/doc/1.8.0/). | 
|---|
| 19 | * | 
|---|
| 20 | * \section unittest-structure Directory structure | 
|---|
| 21 | * | 
|---|
| 22 | *  Unit tests are always located in a subfolder \b unittests of the component | 
|---|
| 23 | *  that they test, e.g. if checking one of the Parsers, then its unit test | 
|---|
| 24 | *  resides in \b src/Parser/unittests. | 
|---|
| 25 | * | 
|---|
| 26 | * \section unittest-launch-all Launching all tests | 
|---|
| 27 | * | 
|---|
| 28 | *  All unit tests can be launched as follows: | 
|---|
| 29 | *  -# Enter the build directory | 
|---|
| 30 | *  -# Enter \b src/unittests | 
|---|
| 31 | *  -# Run | 
|---|
| 32 | *  \code make check | 
|---|
| 33 | *  \endcode | 
|---|
| 34 | * | 
|---|
| 35 | * This will run all present unit tests one after the other. | 
|---|
| 36 | * | 
|---|
| 37 | * \section unittest-launch-some Launching some tests | 
|---|
| 38 | * | 
|---|
| 39 | *  If only some of the tests should be checked, then they have to be launched by | 
|---|
| 40 | *  hand via entering the same directory as in the section before and e.g. | 
|---|
| 41 | *  \code | 
|---|
| 42 | *  ./AnalysisBondsUnitTest | 
|---|
| 43 | *  \endcode | 
|---|
| 44 | *  Note that to allow for debugging of the unit tests, one has to prepend the | 
|---|
| 45 | *  executable as follows: | 
|---|
| 46 | *  \code | 
|---|
| 47 | *  libtool --mode=execute gdb --args ./AnalysisBondsUnitTest | 
|---|
| 48 | *  \endcode | 
|---|
| 49 | *  As we use libtool to take care of shared libraries the executables in | 
|---|
| 50 | *  \b src/unittests are just scripts. The true executables hide in another | 
|---|
| 51 | *  subfolder \b .libs. The scripts set environment variables such that shared | 
|---|
| 52 | *  libraries, which have not been installed so far, are found. | 
|---|
| 53 | * | 
|---|
| 54 | * \section unittest-results Inspecting results | 
|---|
| 55 | * | 
|---|
| 56 | *  Results of the test are shown during run. An \a Ok(2) indicates that | 
|---|
| 57 | *  two tests for the single launched testsuite passed. | 
|---|
| 58 | * | 
|---|
| 59 | * \section unittest-add Adding new tests | 
|---|
| 60 | * | 
|---|
| 61 | *  \attention Name convention of files, (no spaces, use CamelCase) e.g. | 
|---|
| 62 | *  \b AnalysisBondsUnitTest | 
|---|
| 63 | *  - the unit test module should be called as follows: | 
|---|
| 64 | *    -# either the name of the component or the module | 
|---|
| 65 | *    -# followed by UnitTest. | 
|---|
| 66 | *  - the test class should be called as follows: | 
|---|
| 67 | *    -# the name of the class it tests | 
|---|
| 68 | *    -# followed by Test. | 
|---|
| 69 | * | 
|---|
| 70 | *  Adding a new test is as easy as this: | 
|---|
| 71 | *  -# Create a new module for declaration and definition of the unit test | 
|---|
| 72 | *    in a suitable \b unittests subfolder (see above on policy and naming). | 
|---|
| 73 | *    Check out one of the present unit tests and rename, but beware of | 
|---|
| 74 | *    copy&paste errors! | 
|---|
| 75 | *  -# Add the test to the \b Makefile.am contained in \b unittests. | 
|---|
| 76 | * | 
|---|
| 77 | *  If there is not yet a \b unittests folder: | 
|---|
| 78 | *  -# Create a new \b Makefile.am, check out one of the present ones to get | 
|---|
| 79 | *    an idea, below is a small list of contained elements. Note that the | 
|---|
| 80 | *    variable must begin with a unique name as all Makefile.am on unit tests | 
|---|
| 81 | *    are included into one big Makefile.am in \b src/unittests. | 
|---|
| 82 | *  -# Add your ...SOURCES and ...HEADERS to TESTSOURCES and TESTHEADERS. | 
|---|
| 83 | *  -# Add an include directive to \b src/unittests/Makefile.am of this | 
|---|
| 84 | *    newly created \b Makefile.am. | 
|---|
| 85 | * | 
|---|
| 86 | *  What's contained in the \b Makefile.am: | 
|---|
| 87 | *  -# ...SOURCES and ...HEADERS gathering all source and header files in this | 
|---|
| 88 | *    \b unittests folder (this is needed for the test program that contains | 
|---|
| 89 | *    all unit test in one executable). | 
|---|
| 90 | *  -# ...TESTS gathering all test programs in this \b unittests folder. | 
|---|
| 91 | *  -# ...TESTS is added to TESTS, check_PROGRAMS, noinst_PROGRAMS such that | 
|---|
| 92 | *    it is known that they are just tests, programs for \a make \a check and | 
|---|
| 93 | *    are not to be installed. | 
|---|
| 94 | *  -# ...LIBS gathers general libs that all of the tests in this \b unittests | 
|---|
| 95 | *    folder share. | 
|---|
| 96 | *  -# for each unit test: | 
|---|
| 97 | *    -# ...SOURCES gathers all source files that are required for the test. | 
|---|
| 98 | *    -# ...LDADD gathers all libs that are required for compilation. |
