我正在使用TestNG框架编写测试。除了一个测试,当我检查服务失败并且我期待异常类时,一切正常。
这是我的代码:
@Test(expectedExceptions = BookNotFoundException.class)
public void findBookFailureTest() throws BookNotFoundException{
when(booksRepository.findOne(new Long(1))).thenReturn(book);
booksService.findBook(new Long(67));
}
这是测试结果:
Results :
Failed tests:
findBookFailureTest(pl.library.services.BooksServiceImplTest): (..)
Tests run: 7, Failures: 1, Errors: 0, Skipped: 0
为什么测试失败,即使我指定我期望Exception?

好的问题解决了。我必须告诉我的Mock对象,在某些情况下,它必须抛出异常。
这是我的BooksService方法代码:
public Book findBook(Long id) throws BookNotFoundException {
try {
return booksRepository.findOne(id);
} catch (Exception e) {
throw new BookNotFoundException();
}
}
这是工作测试:
@Test(expectedExceptions = BookNotFoundException.class)
public void findBookFailureTest() throws BookNotFoundException{
Long id = new Long(65);
when(booksRepository.findOne(id)).thenThrow(Exception.class);
booksService.findBook(id);
}
感谢您的回答。它对我很有帮助。 :)
