pytest-llm-agent 0.1.2

LLM Agent for working with pytest

pytest-llm-agent

CLI helper to work with unit tests for your codebase.

Installation

Install from PyPI with pip:

pip install pytest-llm-agent

Configuration

You can choose model and add general default prompt

[tool.pytest-llm-agent]
model = "gpt-5"
# general_prompt = "Optional extra system prompt for the agent"

Secrets can be supplied through environment variables prefixed with PYTEST_LLM_AGENT_. For example, set PYTEST_LLM_AGENT_API_KEY in your shell and the agent will receive API_KEY in its environment at runtime.

EXPORT PYTEST_LLM_AGENT_API_KEY=foo

Usage

After configuring your project, run the CLI to generate tests for a specific function, method, or class:

pytest-llm-agent target path/to/module.py:ClassName.method tests/test_module.py

You can optionally pass additional instructions to steer generation:

pytest-llm-agent target path/to/module.py::function tests/test_module.py --prompt "Focus on edge cases"

Contribution

Very welcome. Make sure you also update tests if you add some services logic.
