Testing Instructions

## Running the unit tests

You need to compile ginkgo with -DGINKGO_BUILD_TESTS=ON option to be able to run the tests.

### Using make test

After configuring Ginkgo, use the following command inside the build folder to run all tests:

make test

The output should contain several lines of the form:

Start 1: path/to/test
1/13 Test #1: path/to/test ............................. Passed 0.01 sec

To run only a specific test and see more details results (e.g. if a test failed) run the following from the build folder:

./path/to/test

where path/to/test is the path returned by make test.

### Using make quick_test

After compiling Ginkgo, use the following command inside the build folder to run a small subset of tests that should execute quickly:

make quick_test

These tests do not use GPU features except for a few device property queries, so they may still fail if Ginkgo was compiled with GPU support, but no such GPU is available. The output is equivalent to make test.

### Using CTest

The tests can also be ran through CTest from the command line, for example when in a configured build directory:

ctest -T start -T build -T test -T submit

Will start a new test campaign (usually in Experimental mode), build Ginkgo with the set configuration, run the tests and submit the results to our CDash dashboard.

Another option is to use Ginkgo's CTest script which is configured to build Ginkgo with default settings, runs the tests and submits the test to our CDash dashboard automatically.

To run the script, use the following command:

ctest -S cmake/CTestScript.cmake

The default settings are for our own CI system. Feel free to configure the script before launching it through variables or by directly changing its values. A documentation can be found in the script itself.
