我對一個較舊的 Ruby 庫做出了開源貢獻，以修復上游依賴項更改的幾個錯誤。我認為它運行良好并修補了問題，但是，RSpec 測驗失敗并出現我無法理解的錯誤訊息。

我怎么讀這個？Ruby 的 RSpec 測驗替身之間#<foo>有什么區別？#[foo]
uj5u.com熱心網友回復：
當我看到這兩行
expected: (#<Double "rec_address">, "WyIweHRlc3QwMDAwdGVzdDAwMDB0ZXN0MDAwMHRlc3QwMDAwdGVzdDAwMDB0ZXN0MDAwMHRlc3QwMDAwdGVzdDAwMDB0ZXN0MDAw...DAwMHRlc3QwMDAwdGVzdDAwMDB0ZXN0MDAwMHRlc3QwMDAwdGVzdDAwMDB0ZXN0MDAwMHRlc3QwMDAwdGVzdDAwMDBcIn0iXQ==")
