Installation

This is a guide how to install Moto for contributors.

The following software is assumed to be present:

  • Python 3.x

  • Docker

It is recommended to work from some kind of virtual environment, i.e. virtualenv, to prevent cross-contamination with other projects. From within such a virtualenv, run the following command to install all required dependencies:

make init

With all dependencies installed, run the following command to run all the tests and verify your environment is ready:

make test

Note that this may take awhile - there are many services, and each service will have a boatload of tests.

To verify all tests pass for a specific service, for example for s3, run these commands manually:

flake8 moto/s3
black --check moto/s3 tests/test_s3
pylint tests/test_s3
pytest -sv tests/test_s3

If black fails, you can run the following command to automatically format the offending files:

make format

If any of these steps fail, please see our FAQ or open an issue on Github.
