What problem does it solve?

Automates and standardizes testing of Typer/Click-based Python CLIs using CliRunner, reducing flaky tests and improving reliability.

Core Features & Use Cases

  • CliRunner-based isolation: Tests execute CLI commands without spawning subprocesses, capturing stdout and stderr.
  • Fixtures and test structure: Provides conftest.py fixtures for reusable test setup.
  • Comprehensive coverage: Tests exit codes, stdout/stderr capture, interactive prompts, and isolated filesystem scenarios.
  • Practical examples: Guides how to structure tests for common Typer/Click patterns and real-world CLI workflows.

Quick Start

Run pytest in your Typer project to start writing CliRunner-based tests for your CLI.
