我正在使用摩卡和超级测试来创建功能测试。以下是测试的副本。
it("should verify user POST /api/User/confirm", function (done) {
app.models.Users.findById(userId, function (err, usr) {
json('get', '/api/user/confirm?uid=' + userId + '&token=' + usr.verificationToken)
.expect(204,done);
});
});
但是，此测试返回：

此时我正在使用最新版本的环回。谁能指出我正确的方向？
这
通常是由于代码中多次使用res.send()造成的。 我会检查一下是否是这种情况。
