Question

我在Java Spark中有简单的restfull api。获得单用户的单元测试按预期成功通过，而不是不存在用户的失败案例。单元测试：

@Test
public void testGetNonExistingUser() {
    String userId = "5284c69d-ab72-4703-ba84-ce4feafd456f";
    Response response = request("GET", "/user/" + userId);
}

返回输出：

正在spark中处理此异常的代码。

get("/user/:id", (request, response) -> userDAO.getUser(request.params(":id")), JSONUtil.json());

after((request, response) -> {
    response.type("application/json");
});

exception(IllegalArgumentException.class, (exception, request, response) -> {
    response.status(FAILED_RESPONSE);
    response.body(JSONUtil.toJson(new ResponseError(exception)));
});

exception(CustomException.class, (exception, request, response) -> {
    response.status(FAILED_RESPONSE);
    response.body(JSONUtil.toJson(new ResponseError(exception)));
});

代码中有一个引发异常的地方。

private void checkIfIdAlreadyExists(String id) throws CustomException {
if (!users.containsKey(id)) {
    String message = "User with id=" + id + " not exists";
    throw new CustomException(message);
}
}

如何对不存在的用户进行正确的单元测试？

请求的路由尚未在Spark中映射？
