如何爲ruby編寫rspec測試使用Git的腳本

Question

我有一個Ruby腳本，用於檢查git repo和url端點上的文件之間的變化。如果存在更改，它會提交併推送到回購站。我想爲此腳本編寫rspec測試，但是我無法理解如何執行此操作，因爲我不希望測試將任何事情推送到實際的Git倉庫。我想我需要建立某種模擬存儲庫，但我不完全確定。任何有關如何最好地編寫這樣的腳本的單元測試的建議將不勝感激。

我認爲你可以利用的事實，這是完全合法的推到當地的「裸」庫，即您將需要進行如下操作：

1. 創建一個「裸」倉庫repo1（即一個沒有工作副本的存儲庫，它完全由.git文件夾的內容組成
2. 從repo1克隆常規存儲庫repo2。
3. 按照您通常在repo2（添加，提交，推送）中所做的任何更改。檢查推送是否成功。
4. 檢查數據是否可用repo1。

下面是一個示例控制檯會話在我/tmp目錄：
