VCRが有効なテストでProjectsテーブルに追加のレコードが追加され、そのレコードが追加のテスト全体に渡って失敗するため、テスト終了時にロールバックされます。具体的には、Railsのフィクスチャで作成された4つのプロジェクトと、VCRカセットが追加されたプロジェクトを追加するテストがあります。そのテストは常に成功しますが、データベースはその後4つのプロジェクトにリセットされません。VCRがデータベースの変更をロールバックしないテスト
便利なことに、このプロジェクトはオープンソースなので、あなた自身で実行することができます。このバグはマスターのhttps://github.com/linuxfoundation/cii-best-practices-badge（checkout commit 048776f）に表示されるため、一時的な回避策は得られません。問題の原因となったテストはhttps://github.com/linuxfoundation/cii-best-practices-badge/blob/master/test/features/github_login_test.rb（VCRカセットを使用）はGithubにログインし、テストユーザーからパブリックプロジェクトのリストを取得します。 https://github.com/blowmage/minitest-rails-capybara gemでカピバラを使用しています。
SEED=41779 rake testで実行すると、VCRを使用するテストは成功しますが、4つのプロジェクトではなく5がカウントされるため、後のテストに失敗します。
ここには、最後にROLLBACKが呼び出されましたが、テストの開始時にSAVEPOINTが指定されていないことがわかります。

任意のアイデアROLLBACKが成功するようにSAVEPOINTを設定するには、このテストを取得する方法？私はVCR（これは私がhttps://github.com/vcr/vcr/issues/586に提出したもの）のバグに遭遇していると思うが、確かめるのは難しい。
ありがとうございました！確かめます。 – dankohn
