# pytest-embedded-jtag — Make pytest-embedded plugin work with JTAG.

License: permissive · Maintenance: active · Downloads: 172.6K/mo

## What it is and what it does

pytest-embedded-jtag is a service module for the pytest-embedded plugin that extends embedded system testing to include JTAG-based debugging. It integrates utilities for communicating with embedded targets via JTAG interfaces during test execution.

This package is typically used as an optional service when testing embedded systems that require JTAG connectivity. It provides fixtures and utilities for interacting with embedded devices through JTAG, complementing the core pytest-embedded plugin's other embedded testing features. The package requires Python 3.10 or later and depends on pytest-embedded-serial as its runtime foundation.

Use it for:

- Debug and test embedded microcontrollers via JTAG during automated test runs
- Inspect and interact with embedded device state during pytest test execution
- Integrate JTAG-based hardware testing into continuous integration pipelines
- Test embedded systems that require JTAG connectivity as part of pytest workflows

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Adds JTAG debugging utilities to pytest-embedded for testing embedded systems via JTAG interfaces.

Yes, if you are testing embedded systems with JTAG interfaces and already use pytest-embedded. The package is actively maintained, has no known vulnerabilities, installs with low friction, and carries a permissive license. Install it only if you need JTAG debugging capabilities; it is an optional service.

## Install

pip install pytest-embedded-jtag
uv add pytest-embedded-jtag
poetry add pytest-embedded-jtag

## Installing pytest-embedded-jtag

Before you install: Low friction install with a single runtime dependency (pytest-embedded-serial). Actively maintained with a recent release 59 days ago and no known vulnerabilities.

License in practice: Permissive license allows free use, modification, and distribution with minimal restrictions.

Quickstart:

pip install pytest-embedded-jtag
pytest --embedded-services jtag test_file.py

Python 3.10 or later required; JTAG hardware and associated system tools must be available.

Verify before relying:

- Whether OpenOCD and GDB must be installed separately on the system for JTAG functionality
- Specific JTAG hardware or adapter requirements beyond software dependencies
- Whether this service requires explicit activation via pytest command-line flags
