* django_webtest *を使用してビューをテストし、* django_nose_selenium *を使用してサイトのajaxをテストしています（ユニットテストの実行時にdebug = Falseであるため、webtest.selを機能させることができず、静的ファイルが提供されませんでした）。

私は完全なテストスイートを使用して実行して ./manage.py test project --with-selenium --with-cherrypyliveserverおり、django_webtestとseleniumテストの間で不安定な動作を繰り返しています。django webtestの数が奇数の場合、スイートは合格するようです。偶数の場合、SAVEPOINTはトランザクションブロックの例外でのみ使用できます（以下のスタックを参照）。簡単なテストケース（assertTrue（2 == 1 + 1））を追加することで発見しました。

これはcherrypyサーバーの設定に関連している可能性がありますか？何が起こっているのかについて何か考えはありますか？ビューとajaxをテストするためにどのようなツールの組み合わせを使用していますか？

問題なく webtest.sel を使用しています。テスト中の場合は、静的ファイルを提供するためにいくつかのものを追加するだけです

環境変数を言ってみましょう：

TEST=True ./manage.py test project

次に、urls.py で:

if settings.DEBUG or 'TEST' in os.environ:
    # serve static files
