Managing dependencies Dependency groups Poetry provides a way to organize your dependencies by groups. For instance, you might have dependencies that are only needed to test your project or to build the documentation. To declare a new dependency group, use a tool.poetry.group.<group> section where <group> is the name of your dependency group (for instance, test): [tool.poetry.group.test] # This part can be left out [tool.poetry.group.test.dependencies] pytest = "^6.0.0" pytest-mock = "*" Note All dependencies must be compatible with each other across groups since they will be resolved regardless of whether they are required for installation or not (see Installing group dependencies).

The pyproject.toml file The tool.poetry section of the pyproject.toml file is composed of multiple sections. package-mode Whether Poetry operates in package mode (default) or not. Optional See basic usage for more information. package-mode = false name The name of the package. Required in package mode This should be a valid name as defined by PEP 508. name = "my-package" version The version of the package. Required in package mode This should be a valid PEP 440 string.
