# Step 6: Adding Support for a Testing Dashboard

Adding support for submitting our test results to a dashboard is simple. We already defined a number of tests for our project in Testing Support. Now we just have to run those tests and submit them to a dashboard. To include support for dashboards we include the `CTest` module in our top-level `CMakeLists.txt`.

Replace:

CMakeLists.txt

    enable_testing()

With:

CMakeLists.txt

    include(CTest)

The `CTest` module will automatically call `enable_testing()`, so we can remove it from our CMake files.

We will also need to acquire a `CTestConfig.cmake` file to be placed in the top-level directory where we can specify information to CTest about the project. It contains:

- The project name

- The project "Nightly" start time

  - The time when a 24 hour "day" starts for this project.

- The URL of the CDash instance where the submission's generated documents will be sent

One has been provided for you in this directory. It would normally be downloaded from the `Settings` page of the project on the CDash instance that will host and display the test results. Once downloaded from CDash, the file should not be modified locally.

CTestConfig.cmake

    set(CTEST_PROJECT_NAME "CMakeTutorial")
    set(CTEST_NIGHTLY_START_TIME "00:00:00 EST")

    set(CTEST_DROP_METHOD "http")
    set(CTEST_DROP_SITE "my.cdash.org")
    set(CTEST_DROP_LOCATION "/submit.php?project=CMakeTutorial")
    set(CTEST_DROP_SITE_CDASH TRUE)

The `ctest` executable will read in this file when it runs. To create a simple dashboard you can run the `cmake` executable or the `cmake-gui` to configure the project, but do not build it yet. Instead, change directory to the binary tree, and then run:

    ctest [-VV] -D Experimental

Remember, for multi-config generators (e.g. Visual Studio), the configuration type must be specified:

    ctest [-VV] -C Debug -D Experimental

Or, from an IDE, build the `Experimental` target.

The `ctest` executable will build and test the project and submit the results to Kitware's public dashboard: https://my.cdash.org/index.php?project=CMakeTutorial.
