+The build system supports two test frameworks - NCBI and CMake one. To use NCBI test framework on Linux, in the build directory execute the following command:
+
+    make check
+
+Test outputs can be found in *CMake-GCC730-ReleaseDLL/check* directory. Please note that the NCBI test framework does not support [Unrelated source trees](#ch_cmconfig._unrelated) and the [Toolkit Conan package](#ch_cmconfig._Conan_prebuilt).
+
+To use CMake testing framework:
+
+    On Linux: make test
+    In Visual Studio or XCode: "build" RUN_TESTS target
+
+Refer to [CMake documentation](https://cmake.org/cmake/help/v3.14/manual/ctest.1.html) for details.
+In case of CMake testing framework, test outputs can be found in *CMake-GCC730-ReleaseDLL/testing* directory.
+
+When using the Toolkit as [Conan package](#ch_cmconfig._Conan_prebuilt), availability of CTest framework should be explicitely requested by defining *NCBI_PTBCFG_ADDTEST* CMake variable before finding the Toolkit:

+    find_package(ncbi-cxx-toolkit-core REQUIRED)
+
+It also requires using [NCBIptb](#ch_cmconfig._NCBIptb) in your project source tree.
