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.
