我在我的应用中测试方法。我正在从存储的联系人生成一个vcard并将其与硬编码的vcard进行比较。它们应该完全相同vcard，它们是。logcat。问题是测试失败了，不明白如何。
从\n\n输出看起来很明显它没有打印双新行（public void testGetContactAsVcard() {
String vcardActual = utils.getContactAsVcard(contact.getAllContactIds().get(0));
// This is the vcard for the first contact (position zero)
String vcardExpected = "BEGIN:VCARD" +

输出：
vcardActual正如您所看到的，在PHOTO和NOTE之间的vcardExpected中有一个新的空行，但\n\n中不会发生这种情况。已在NOTE之前放置PHOTO。
我希望NOTE和{{1}}之间有一个空的新行，但出于某种原因，它不会发生。为什么以及如何发生这种情况？
答案 0 :(得分：0)
得到了解决方案。
首先 - ＆gt; 永远不要完全依赖logcat！新行总是在那里，但由于某种我还不知道的原因，logcat没有输出它。
第二 - ＆gt; JUnit正在添加[，]，<，>和new line。
解决方案：从两个字符串中删除所有空格和新行并进行比较。
final String vcardNoWhiteSpacesNoNewLinesExpected = vcardExpected.replace("\n", "").replace("\r", "").replace(" ", "");
final String vcardNoWhiteSpacesNoNewLinesActual = vcardActual.replace("\n", "").replace("\r", "").replace(" ", "");
他们现在都匹配，问题解决了。
