如何将值注入模拟对象的构造函数或通过setter?我收到了意外调用错误

我的问题:如何通过构造函数或setter创建模拟对象并注入属性?

我收到意外的调用错误。我正在@Before中的模拟对象上设置一个set来为我的BAPI设置name属性。当我执行测试时,我的setName方法出现意外的调用错误。但是,我真的不想测试这种方法。我只是插入它,所以当我的代码执行方法checkParm(b)时,值就在那里。

如果我没有对模拟器的setter添加任何期望,我会得到意外的调用。但是,如果我将此代码添加到期望中,我仍然会得到意外的调用。

        ignoring(mockAdapter).setName(BAPI_NAME);
        inSequence(sequence);

这是我的@Before方法

@Before
public void setUp() throws Exception {

    objectUnderTest = new ApoSAPExtractor();

    mockAdapter = context.mock(BapiAdapter.class);
    mockAdapter.setName(BAPI_NAME);

    apoResults = new ApoResults();
    apoParameterBean = new ApoParameterBean();
}

然后我的测试方法:

@Test
public final void testExtract() throws Exception {

    final Sequence sequence = context.sequence(SEQUENCE);

    context.checking(new Expectations() {{

        atLeast(1).of(mockAdapter).getName();
        will(returnValue(new String())); 
        inSequence(sequence);

        oneOf(mockAdapter).activate();
        inSequence(sequence);

        oneOf(mockAdapter).getImportTableParameter(IM_PARMS);
        inSequence(sequence);
        will(returnValue(JCoTable.class)); 

        oneOf(mockAdapter).execute(); 
        inSequence(sequence);

        oneOf(mockAdapter).getExportTableAdapter(EX_PO_APO); 
        inSequence(sequence);
        will(returnValue(new TableAdapter(with(any(JCoTable.class)))));

    }});

    objectUnderTest.extract(mockAdapter, apoParameterBean);     
    context.assertIsSatisfied();

}

我正在嘲笑的课程:

     public class ApoSAPExtractor implements SAPExtractor<ApoResults, ApoParameterBean> {

private final static Logger logger = Logger.getLogger(ApoSAPExtractor.class);

public List<ApoResults> extract(BapiAdapter b, ApoParameterBean pb) throws JCoException, Exception {

    checkParm(b);

    List<ApoResults>list = new ArrayList<ApoResults>();
    try {
        b.activate();

        JCoTable itp = b.getImportTableParameter(APOConstants.BAPI_IM_PARMS);
        itp.appendRow();

        JCoTable t = itp.getTable(APOConstants.BAPI_DOC_TYPES);
        Utils.appendParm(t, pb.getDocTypes());

        b.execute();

        TableAdapter ta = b.getExportTableAdapter(APOConstants.BAPI_EX_PO_APO);

        for (int i = 0; i < ta.size(); i++) {

            ApoResults ar = new ApoResults();

            ... lots of setters ...

            list.add(ar);

            ta.next();
        }

    } catch (Exception e) {
        logger.info(String.format("Program %s failed.",this.getClass().getSimpleName(),  "failed"));
        e.printStackTrace();
        throw e;
    }

    return list;
}

答案 0 :(得分:1)

你不能把东西注入模拟,你可以设置它的期望

而不是这个(它给你意想不到的例外):

mockAdapter.setName(BAPI_NAME);

你可能会按照你的期望这样做:

atLeast(1).of(mockAdapter).getName();
will(returnValue(BAPI_NAME));
