From f61f0e881e63b97b98ab65f1500c071280a6c57d Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 11 Nov 2025 07:32:10 +0000 Subject: [PATCH 1/2] Add test for plugin discovery from examples/basic This test verifies that a new plugin (like the one in examples/basic) is properly picked up by the launcher when installed. The test: - Installs the example plugin in editable mode - Discovers it via the PluginLoader - Verifies that commands and processes are correctly registered - Cleans up by uninstalling the plugin after the test The test handles Python import caching issues by: - Adding the plugin path to sys.path for editable installs - Invalidating import caches - Using distributions() to force fresh entry point discovery --- my/plugins/tests/test_discover_and_load.py | 132 +++++++++++++++++++++ 1 file changed, 132 insertions(+) diff --git a/my/plugins/tests/test_discover_and_load.py b/my/plugins/tests/test_discover_and_load.py index 5a6b675..3d47db3 100644 --- a/my/plugins/tests/test_discover_and_load.py +++ b/my/plugins/tests/test_discover_and_load.py @@ -1,6 +1,9 @@ import argparse +import importlib +import subprocess import sys from dataclasses import dataclass +from pathlib import Path from typing import Any, Dict, List, Set import pytest @@ -82,3 +85,132 @@ class A(Command): assert "test_discover_and_load" in p.plugins assert p.plugins["test_discover_and_load"].commands.as_list() == [("Printer", A)] + + +@pytest.fixture +def example_plugin_installed(): + """Fixture that installs the example plugin and cleans it up after the test.""" + # Get the path to the example plugin + test_dir = Path(__file__).parent + repo_root = test_dir.parent.parent.parent + example_plugin_dir = repo_root / "examples" / "basic" + + # Verify the example plugin directory exists + assert example_plugin_dir.exists(), f"Example plugin not found at {example_plugin_dir}" + + # Install the plugin in editable mode + result = subprocess.run( + [sys.executable, "-m", "pip", "install", "-e", str(example_plugin_dir)], + capture_output=True, + text=True + ) + + if result.returncode != 0: + pytest.fail(f"Failed to install example plugin: {result.stderr}") + + # For editable installs, we need to add the package path to sys.path + # so it can be imported in the same Python process + original_sys_path = sys.path.copy() + if example_plugin_dir not in sys.path: + sys.path.insert(0, str(example_plugin_dir)) + + # Invalidate Python's import caches to make the newly installed package discoverable + importlib.invalidate_caches() + + # Invalidate the entry points cache to force discovery of the newly installed plugin + if sys.version_info < (3, 10): + import importlib_metadata as im + try: + im.distributions.cache_clear() + except AttributeError: + pass + else: + import importlib.metadata as im + try: + im.distributions.cache_clear() + except AttributeError: + pass + + yield example_plugin_dir + + # Restore sys.path + sys.path = original_sys_path + + # Cleanup: uninstall the plugin + subprocess.run( + [sys.executable, "-m", "pip", "uninstall", "-y", "yeti-example"], + capture_output=True, + text=True + ) + + # Invalidate cache again after uninstall + importlib.invalidate_caches() + if sys.version_info < (3, 10): + import importlib_metadata as im + try: + im.distributions.cache_clear() + except AttributeError: + pass + else: + import importlib.metadata as im + try: + im.distributions.cache_clear() + except AttributeError: + pass + + +def test_example_plugin_discovery(example_plugin_installed): + """Test that a new plugin (like examples/basic) is discovered by the launcher.""" + # Create a fresh PluginLoader to discover all installed plugins + loader = PluginLoader() + + # Force fresh discovery by getting entry points from distributions + # This bypasses any caching issues + if sys.version_info < (3, 10): + from importlib_metadata import distributions + else: + from importlib.metadata import distributions + + # Manually discover entry points from all distributions + for dist in distributions(): + if dist.entry_points: + for ep in dist.entry_points: + if ep.group == "my.plugins.command": + loader.load_command(ep) + elif ep.group == "my.plugins.process": + loader.load_process(ep) + elif ep.group == "my.plugins.registry": + loader.load_registry(ep) + + # Verify that the yeti_example plugin was discovered + assert "yeti_example" in loader.plugins, ( + f"Plugin 'yeti_example' not found.
