我有一個問題。 我不明白爲什麼mockito會出現異常。 RecordWriter在該文件中寫入一條記錄。我想驗證它是否寫入。 我實現了另一個功能,我試圖模擬(OutputStream.class),但結果是一樣的。我目前的測試是:通緝但不是援引:Mockito測試

try (RecordWriter writer = new RecordWriter(serverAlias)) 
      { 
      RecordWriter wr = mock(RecordWriter.class); 
      writer.writeRecordToFile(httpRecord.printRecord().getBytes(CHARSET_UTF8)); 
      verify(wr,times(1)).writeRecordToFile(httpRecord.printRecord().getBytes(CHARSET_UTF8)); 

      } 

唯一的例外是:

Wanted but not invoked: 
recordWriter.writeRecordToFile(
    [50, 48, 49, 54, 48, 51, 49, 56, 45, 49, 50, 49, 52, 49, 51, 44, 50, 48, 49, 54, 48, 51, 49, 56, 49, 49, 50, 50, 44, 50, 48, 49, 54, 48, 51, 49, 56, 49, 49, 50, 57, 44, 51, 51, 51, 54, 53, 52, 56, 55, 57, 56, 44, 112, 114, 111, 118, 97, 44, 104, 101, 108, 108, 111, 44, 105, 32, 100, 111, 110, 39, 116, 32, 107, 110, 111, 119, 10] 
);

Actually, there were zero interactions with this mock.

感謝所有。

您不在模擬上調用writeRecordToFile方法。 – Reins

Thx。我在RecordWriting中有一些功能阻止寫入。例如,如果目錄的大小大於2MB,則ReportWriting不會寫入更多內容。如果我調用wr.writeRecordToFile(),可以用mockito來測試它嗎? –

您不在模擬上調用writeRecordToFile方法。

您有:

1)一個真實的例子 - RecordWriter writer = new RecordWriter(serverAlias)

2)模擬 - RecordWriter wr = mock(RecordWriter.class);

和你打電話的真實實例(作家的方法),並嘗試以驗證模擬(wr)與互動。

更改方法調用:wr.writeRecordToFile(httpRecord.printRecord().getBytes(CHARSET_UTF8));

,它應該工作。雖然這似乎是一個毫無意義的測試,如果你問我。
