単体でのrye run pytest awesome、rye run pytest fabulousは通る
--collect-onlyも渡すと
code:txt
collected 1 item / 1 error
<Dir rye-workspace-example>
<Dir awesome>
<Package tests>
<Module test_awesome.py>
<Function test_awesome>
awesomeとfabulousでtestsパッケージが同名
rye run pytest --import-mode importlib で解決
code:collectされるようになる
collected 2 items
<Dir rye-workspace-example>
<Dir awesome>
<Package tests>
<Module test_awesome.py>
<Function test_awesome>
<Dir fabulous>
<Package tests>
<Module test_fabulous.py>
<Function test_fabulous>
デフォルトはprependモード
awesome/testsのパスをsys.pathにprependしたということではないか
なのでfabulous/testsの中のモジュールが（awesome/testsを探しても）見つからなくて上記のエラー、という理解をした
