<p>Nightly -&gt; 4.10</p> <p><b>New page</b></p><div>&lt;noinclude&gt;{{documentation/versioncheck}}&lt;/noinclude&gt;<br /> == Goal ==<br /> <br /> Goal of Cxx tests is to test C++ classes as comprehensively as possible in the simplest possible environment (with minimum usage of other classes).<br /> <br /> The tests are run as part of the nightly test process and submitted to [http://slicer.cdash.org/index.php?project=Slicer4 the slicer dashboard].<br /> <br /> == Implementation ==<br /> <br /> * Test execution is managed by [http://www.cmake.org/Wiki/CMake/Testing_With_CTest CMake/CTest]<br /> * To reduce the number of individual executable files, typically many test cases are packaged into a single executable using and CTK's [http://www.commontk.org/docs/html/group__CMakeUtilities.html SIMPLE_TEST utilities]<br /> * The test process must exit with zero (EXIT_SUCCESS) error code in case of success and non-zero (EXIT_FAILURE) in case of failure<br /> * It is strongly recommended to exit with failure if any unexpected VTK error or warning messages are logged. To achieve this, use the [https://github.com/Slicer/Slicer/blob/master/Libs/vtkAddon/vtkTestingOutputWindow.h vtkTestingOutputWindow] class (and its convenience macros) defined in the vtkAddon library<br /> ** In the CMakeLists.txt of your Cxx tests (see [https://github.com/Slicer/Slicer/blob/master/Libs/MRML/Widgets/Testing/CMakeLists.txt Libs\MRML\Widgets\Testing\CMakeLists.txt] as an example):<br /> *** Add ''TESTING_OUTPUT_INIT()'' to ''CMAKE_TESTDRIVER_BEFORE_TESTMAIN''<br /> *** Add ''TESTING_OUTPUT_ASSERT_WARNINGS_ERRORS(0)'' to ''CMAKE_TESTDRIVER_AFTER_TESTMAIN''<br /> *** Add ''#include &lt;vtkTestingOutputWindow.h&gt;'' to the included ''EXTRA_INCLUDE'' header file.<br /> ** In your testing code, if you expect errors or warnings: include ''vtkTestingOutputWindow.h'' and put code that logs errors or warnings between these macros (see examples in [https://github.com/Slicer/Slicer/blob/master/Libs/MRML/Widgets/Testing/ Libs\MRML\Widgets\Testing]):<br /> *** ''TESTING_OUTPUT_IGNORE_WARNINGS_ERRORS_BEGIN()'' / ''TESTING_OUTPUT_IGNORE_WARNINGS_ERRORS_END()'' – if errors or warnings may be logged<br /> *** ''TESTING_OUTPUT_ASSERT_WARNINGS_BEGIN()'' / ''TESTING_OUTPUT_ASSERT_WARNINGS_END()'' – if errors or warnings must be logged</div>
