pyproject.tomlにテスト実行コマンド追加

[tool.pdm.scripts]
test = "python -m unittest discover tests"

れおろめ

pytestを導入

pdm add pytest

テスト実行を常駐させる

pytest-watchをインストール

pdm add pytest-watch

pyprojet.tomlに追加

test = "pytest-watch"

pytest-watchコマンドをコンソール上で実行しても動かないけどそれはpdm内の依存関係で管理しているのでプロジェクト内だけのコマンドとして有効

れおろめ

pytest-mocker を追加して非同期処理やライブラリをモックする

pytest-mockerを追加

pdm add pytest-mocker

conftest.pyを作成

conftest.py

@pytest.fixture(scope="module", autouse=True)
def scope_module(mocker):
    print("    setup before module")
    mocker.patch("python_bitbankcc.private", new=bitbankcc_private_Dummy)
    yield
    print("    teardown after module")

エラーになる「Failed: ScopeMismatch: You tried to access the function scoped fixture mocker with a module scoped request object, involved factories」
mocker から module_mocker に変更する

conftest.py

@pytest.fixture(scope="module", autouse=True)
def scope_module(module_mocker):
    print("    setup before module")
    module_mocker.patch("python_bitbankcc.private", new=bitbankcc_private_Dummy)
    yield
    print("    teardown after module")
