mm-test-adapters

This builds device adapters commonly used for testing and development of mmCoreAndDevices (micro-manager).

• DemoCamera
• Utilities
• SequenceTester
• NotificationTester

It makes these builds available in two places:

1. Via GitHub releases: https://github.com/micro-manager/mm-test-adapters/releases

   These releases include just the shared libraries for these adapters.

2. Via a PyPI package:

   pip install mm-test-adapters
   

   This package includes the shared libraries, and a single public method, mm_test_adapters.device_adapter_path, which returns a path to the device adapters folder.

Using PyPI Package

import pymmcore  # or pymmcore_plus
from mm_test_adapters import device_adapter_path

core = pymmcore.CMMCore()
core.setDeviceAdapterSearchPaths([device_adapter_path()])

Build Adapters

To build these locally, you should first have system boost installed:

# macos
brew install boost
# ubuntu
sudo apt-get install libboost-all-dev
# windows
choco install boost-msvc-14.2

uv sync --no-editable
# or
uv run fetch.py --build

Build Python Package

To build an sdist and wheel, run:

uv build

You may optionally set the env var MM_SHA to build a specific commit of mmCoreAndDevices.

Cleanup

If you want to remove all external sources and build files:

make clean

note, the makefile also works on Windows if you have git for windows.

Using Releases on CI

To use these on CI see https://github.com/pymmcore-plus/setup-mm-test-adapters

- name: Install MM test adapters
  uses: pymmcore-plus/setup-mm-test-adapters@main
  with:
    # all inputs are optional
    # version should look like:
    #   literal string 'latest'
    #   DIV -> version: 74
    #   DIV.YYYYMMDD -> version: 74.202508
    version: latest
    destination: ./mm-test-adapters

Using Releases Locally

Download the release you would like to use, then place it wherever Micro-Manager is looking for device adapters.

To have them found by pymmcore-plus, place them in the default pymmcore-plus install location, named Micro-Manager-YYYYMMDD

• Windows: $LOCALAPPDATA/pymmcore-plus/pymmcore-plus/mm/Micro-Manager-YYYYMMDD
• macOS: $HOME/Library/Application Support/pymmcore-plus/mm/Micro-Manager-YYYYMMDD
• Linux: $HOME/.local/share/pymmcore-plus/mm/Micro-Manager-YYYYMMDD

[!TIP] On macOS, you will need to give permissions to allow the shared libraries to run:

xattr -r -d com.apple.quarantine ~/Library/Application\ Support/pymmcore-plus/mm/Micro-Manager-*
