CTest

Configure a project for testing with CTest/CDash

Include this module in the top CMakeLists.txt file of a project to enable testing with CTest and dashboard submissions to CDash:

project(MyProject)
...
include(CTest)

The module automatically creates a BUILD_TESTING option that selects whether to enable testing support (ON by default). After including the module, use code like:

if(BUILD_TESTING)
  # ... CMake code to create tests ...
endif()

to creating tests when testing is enabled.

To enable submissions to a CDash server, create a CTestConfig.cmake file at the top of the project with content such as:

set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
set(CTEST_SUBMIT_URL "http://my.cdash.org/submit.php?project=MyProject")

(the CDash server can provide the file to a project administrator who configures MyProject). Settings in the config file are shared by both this CTest module and the ctest(1) command-line Dashboard Client mode (ctest -S).

While building a project for submission to CDash, CTest scans the build output for errors and warnings and reports them with surrounding context from the build log. This generic approach works for all build tools, but does not give details about the command invocation that produced a given problem. One may get more detailed reports by setting the CTEST_USE_LAUNCHERS variable:

set(CTEST_USE_LAUNCHERS 1)

in the CTestConfig.cmake file.
