Junit 异常测试用例 [关闭]

public class TipException extends Exception {
    private final Object mSource;
    private final Object mObjectInError;
    private final Throwable mCause;

    public TipException(Object source, Object objectInError, Throwable cause, String message) {
        super(message);
        this.mSource = source;
        this.mObjectInError = objectInError;
        this.mCause = cause;
    }
}

我需要为这个具有更多方法的简单异常类编写 Junit 测试用例。 但由于我是 Junit 的新手，我不知道如何在这里传递一些带有异常的对象。 任何帮助将不胜感激。

尝试一些简单的事情，例如：

 public class TipExceptionTest extends TestCase {
 private final String message = "Exception";
 private final TipException tipException= new TipException("source", "MyObject.class", new NullPointerExcepiton(), message);

 @Test
 public void testTipExceptionWithMessage() {
    Assert.assertEquals(tipException.getMessage(), message);//and if you exposed getter/setter for source etc you could assert as well
 }
}
