Question

public void testCreate() throws ApplicationException {
    DutyDrawback drawback = new DutyDrawback();
    drawback.setSerialNumber("TEST123");
    drawback.setSnProcessInd("Y");
    drawback.setMediaNumber("TEST111");
    drawback.setMnProcessInd("Y");
    drawback.setConfirmedInd("Y");
    drawback.setResponseCode("1");
    drawback.setResponseMsg("MSG");
    drawback.setLastChangedUser("USER");
    drawback.setLastChangedDate(new Date(System.currentTimeMillis()));

    mockILogger.expects(atLeastOnce()).method("informationalEvent");
    Logger.setMockLogger((ILogger) mockILogger.proxy());

    // Set up the statement expectations
    Mock mockStatement = mock(PreparedStatement.class);
    mockStatement.expects(atLeastOnce()).method("setString");
    mockStatement.expects(once()).method("executeUpdate").will(returnValue(1));

    Mock mockStatement1 = mock(PreparedStatement.class);
    mockStatement1.expects(atLeastOnce()).method("setString");
    mockStatement1.expects(once()).method("executeUpdate").will(returnValue(1));

    // Set up the connection expectations
    mockConnection.expects(once()).method("setAutoCommit");
    mockConnection.expects(once()).method("commit");
    mockConnection.expects(once()).method("prepareStatement").will(returnValue(mockStatement1.proxy()));
    mockConnection.expects(once()).method("prepareStatement").will(returnValue(mockStatement.proxy()));

    TVSUtils.setMockConnection((Connection) mockConnection.proxy());
    DutyDrawbackDAO drawbackDAO = new DutyDrawbackDAO();
    int count = drawbackDAO.create(drawback);
    assertEquals(2, count);
}

我得到以下痕迹：

org.jmock.core.DynamicMockError：mockPreparedStatement：意外调用调用：mockPreparedStatement.executeUpdate（）允许：预期至少一次并且已经被调用：setString，是无效的预期一次并被调用：executeUpdate，返回＆lt; 1＆gt;

我不确定我在这里做错了什么？

感谢。

首先，您似乎正在使用jmock1，您可以考虑转移到jmock2。

失败表示你在不期望的时候调用executeUpdate（）。你是不是一次打电话给它？

最后，我通常建议不要编写针对JDBC的模拟测试，即使我多年前写了一篇论文来展示如何做到这一点。我们谈论“只有你拥有的模拟类型”有很多原因，其中一个原因是模拟测试假设第三方实现没有改变。对于JDBC，我建议编写针对真实数据库的小实例运行的集成测试。

如何在jMock中为每个连接模拟2个或多个预准备语句？
