我在测试中使用PowerMockito来模拟私有方法.
validator = spy(new CommentValidator(form, request));
PowerMockito.when(
validator,
method(CommentValidator.class, "isCaptchaValid",
HttpServletRequest.class))
.withArguments(Mockito.any())
.thenReturn(true);
当我运行测试时,我在isCaptchaValid方法的第二行获得了带有NullPointerException的java.lang.reflect.InvocationTargetException,如下所示:
private boolean isCaptchaValid(HttpServletRequest request) {
Captcha captcha =
(Captcha) request.getSession().getAttribute("attribute");
if (captcha == null) {
log.debug(String.format("O valor do captcha da sessão esta nulo. IP: [%s]",
IPUtil.getReaderIp(request)));
return false;
}
if (captcha.isInputValid(
request.getParameter("captcha").toString().toUpperCase())) {
return true;
}
return false;
}
public final Boolean isInputValid(String pInput) {
if (getPuzzle() == null) {
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("puzzle is null and invalid. Will return Boolean.FALSE");
}
return Boolean.FALSE;
}
Boolean returnValue = verifyInput(pInput);
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("Validation of puzzle: " + returnValue);
}
disposePuzzle();
return returnValue;
}
如果我嘲笑它的行为,为什么要考虑方法的实现呢?有没有办法避免这种情况?我需要模拟它的原因是因为我无法提供Captcha对象.
最佳答案 问题解决了
通过电话
PowerMockito.when(
validator,
method(CommentValidator.class, "isCaptchaValid",
HttpServletRequest.class))
.withArguments(Mockito.any())
.thenReturn(true);
首先,方法本身由PowerMockito验证,因此很可能找到NPE.
为了避免这种情况,您需要反转该逻辑.
doReturn(true).when(validator, "isCaptchaValid", any(HttpServletRequest.class));
它使PowerMockito忽略了方法的主体并立即返回你想要的东西.
