Development and Testing Dependencies

requirements_dev.txt

• This file lists dependencies needed for development and testing only.
• It keeps development/testing dependencies separate from production requirements.
• Example: Testing frameworks, linters, mock libraries.

requirements.txt

• This file lists the dependencies required to run the project in production.
• Contains only the packages necessary for deployment.

---

Difference Between requirements_dev.txt and requirements.txt

• requirements.txt → For production environment dependencies.
• requirements_dev.txt → For development & testing environment dependencies.

---

tox.ini

• Used for testing the Python package against different Python versions.
• Tox automates:
  1. Creating virtual environments for different Python versions.
  2. Installing required dependencies.
  3. Running predefined test commands.
• Think of it as a combination of virtualenvwrapper and makefile.
• Creates a .tox folder where environments are stored.

---

pyproject.toml

• Used for configuring Python projects (alternative to setup.cfg).
• Contains metadata:
  • Build system info
  • Package name, version, author, license
  • Dependencies
• Works with modern packaging tools (e.g., Poetry, Flit, setuptools).

---

setup.cfg

• Used by setuptools for project packaging and installation.
• Stores configuration options such as:
  • Metadata (name, version, author)
  • Dependency lists
  • Entry points
  • Other setup-related settings.

Code Style, Formatting, and Linting

Popular Tools

1. pylint – Checks Python code for errors and enforces coding standards.
2. flake8 – Combines multiple tools (pylint, pycodestyle, mccabe) in one.
3. pycodestyle – Checks Python code against PEP 8 style guidelines.

Summary

• Use requirements.txt for production dependencies.
• Use requirements_dev.txt for development/testing dependencies.
• Use tox.ini for testing across different Python versions.
• Use pyproject.toml or setup.cfg for project configuration.
• Follow coding standards with tools like flake8 or pylint.
• Test your application with frameworks like pytest or unittest.
