requirements_dev.txt
We use it for testing.
It makes it easier to install and manage dependencies for development and testing, separate from the dependencies required for production.

difference between requirements_dev.txt and requirements.txt
requirements.txt is used to specify the dependencies required to run the production code of a Python project, while requirements_dev.txt is used to specify the dependencies required for development and testing purposes.

tox.ini
We use it for testing in the Python package, testing against different versions of Python.

how tox works (tox environment creation)

• Install dependencies and packages
• Run commands
• It's a combination of virtualenvwrapper and makefile
• It creates a .tox folder

pyproject.toml
It is used for configuring the Python project. It is an alternative to the setup.cfg file. It contains configuration related to the build system, such as the build tool used, package name, version, author, license, and dependencies.

setup.cfg
In summary, setup.cfg is used by setuptools to configure the packaging and installation of a Python project.

• selenium
• behave
• doctest

Check with the code style formatting and syntax (coding standards)

• pylint
• flake8 (It is best because it contains 3 libraries: pylint, pycodestyle, and mccabe)
• pycodestyle
