Running the ROOT battery of tests

Running all ROOT tests on at least a platform before sending a PR or before pushing anything to the ROOT repository is mandatory. The ROOT continuous integration infrastructure allows to automatically check the PR also on a battery of platform, for example including macos and linux boxes. In order to be able to run all tests, the simple steps below need to be followed

Prepare your development area and build ROOT

mkdir RootDevelopment
cd RootDevelopment
git clone https://github.com/root-project/root
git clone https://github.com/root-project/roottest
mkdir build
cd build
echo Note the cmake options
cmake -DCMAKE_BUILD_TYPE=Debug -Dtesting=ON -Droottest=ON ../root

Inspect and run the tests

From within the build directory

• List all tests: ctest -N
• List all test matching a regex: ctest -N -R myregex
• Run all tests on N cores: ctest -j N
