安卓單元測試 - assertEqual不能使用語言環境值

我想寫一個本地化類來轉換給定段落中的數字和貨幣。這是我試圖運行的測試用例。安卓單元測試 - assertEqual不能使用語言環境值

@Test 
public void localContentTest() throws Exception { 
    String content = "Go Square Wakad, 411057 Pune"; 
    String expectedContent = "Go Square Wakad, 411057 Pune"; 
    String actualString = Localization.localeContent(content, Locale.GERMAN); 
    assertEquals(expectedContent, actualString); 
}

Localization.localeContent是返回字符串的簡單函數。

public static String localeContent(final String content, final Locale locale) { 
     final StringBuilder stringBuilderResult = new StringBuilder(); 
     ... 
     //Something to extract number and get it localize. 

     return stringBuilderResult.toString(); 
    }

在測試輸出我得到這個。我不明白爲什麼即使預期和實際相同測試失敗。

junit.framework.ComparisonFailure: 
Expected :Go Square Wakad, 411057 Pune 
Actual :Go Square Wakad, 411057 Pune

看來你必須在你的實際字符串末尾一個空格：

Expected :"Go Square Wakad, 411057 Pune" 
Actual :"Go Square Wakad, 411057 Pune "

如果沒有，請與我們分享您用來生成實際的串碼。

大聲笑，我要殺了自己..就是這樣......你真棒。感謝名單。我必須問，你是如何在「預期」和「實際」中得到雙引號的。 –

我剛剛發佈了引用，以使我的觀點清楚，那不是實際的控制檯輸出：P 但是您可以做的是檢查並比較字符串長度;如果字符串看起來相同但不具有相同的長度，則可能在末尾有一些空白。 – CodeX
