Zirconium (Zr) Plugin

The Zirconium plugin provides GPIO monitoring and control capabilities.

Quick Start

@pytest.mark.zr
def test_gpio_monitoring(zr, check):
    # Monitor GPIO state changes
    check.that(zr.gpio.heartbeat, "=", True, within_duration_s=2.0)
    check.that(zr.gpio.heartbeat, "=", False, within_duration_s=2.0)

GPIO Access

Reading GPIO States

# Monitor GPIO changes
check.that(zr.gpio.heartbeat, "=", True, within_duration_s=2.0)

Writing GPIO States

# Set GPIO state (only for output GPIOs)
zr.gpio.heartbeat.set(True)

Using with Checker

The Zr plugin works seamlessly with the Checker plugin for GPIO state verification:

def test_gpio_sequence(zr, check):
    # Verify GPIO toggles from True to False within 2 seconds
    check.that(zr.gpio.heartbeat, "=", True, within_duration_s=2.0)
    check.that(zr.gpio.heartbeat, "=", False, within_duration_s=2.0)

    # Verify GPIO stays True for at least 1 second
    check.that(zr.gpio.heartbeat, "=", True, for_duration_s=1.0)
