| '''Important''': We want the code to compile without warnings, but in favour of user-friendliness we did not add the -Werror flag to the build script. Make sure that you compile your code with the -Werror flag, for example by adding {{{export CXXFLAGS+=-Werror}}} to your bashrc. Note that you should build the binary from scratch after this (i.e. remove the builds directory if it exists), since it will not recompile files unless they have been changed. |

Recommended development environment
The requirements for building and running the planner are listed under ObtainingAndRunningFastDownward. Our automated tests have additional dependencies that can be installed as follows:
apt-get install clang-tidy-8 python3.6 python3.7 python3.8 python3-pip valgrind wget python3 -m pip install tox
We recommend using Ubuntu 18.04 or 20.04 for Fast Downward development since these versions are also used by the core developers and they allow installing many dependencies via the package manager.

Running tests
To run all tests under all locally-available Python versions, run tox in the misc/ directory. The command creates Python virtual environments under misc/.tox. The directory uses ~50 MB and is not shown by git status. You can safely delete the directory after the tests have been run. To run a subset of tests, e.g., only the style checks, use tox -e style (see misc/tox.ini for other test environments). Many of the tests that tox executes are Bash/Python scripts or pytest modules, which you can also run individually. To check a pytest module, execute pytest my_module.py.
