jUnit中的ExpectedException？

Question

是否在jUnit中等效于NUnit的ExpectedException或Assert.Throws <>？

Answer 1

您还可以考虑查看ExpectedException类,它提供更丰富的异常匹配.

您不仅可以匹配异常类,还可​​以将自定义匹配器应用于其消息.

Answer 2

junit4:

@Test(expected = org.dom4j.DocumentException.class)
void shouldThrowException() {
    getFile(null);
}

junit3:

void testShouldThrowException() {
    try {
      getFile(null);
      fail("Expected Exception DocumentException");
    } catch(DocumentException e) {}
}
