node.js - 试图使用 supertest 来检查响应的主体 - 得到一个错误

Question

我正在尝试使用 supertest 进行一些测试。这是我要测试的代码片段:

it("should create a new org with valid privileges and input with status 201", function(done) {
  request(app)
    .post("/orgs")
    .send({ name: "new_org", owner: "oldschool@aol.com", timezone: "America/New_York", currency: "USD"})
    .expect(201)
    .end(function(err, res) {
      res.body.should.include("new_org");
      done();
    });
});

我在尝试测试 res 正文时遇到错误:

 TypeError: Object #<Object> has no method 'indexOf'
  at Object.Assertion.include (../api/node_modules/should/lib/should.js:508:21)
  at request.post.send.name (../api/test/orgs/routes.js:24:27)

  at Socket.socketOnData [as ondata] (http.js:1367:20)
  at TCP.onread (net.js:403:27)

这是超测中的错误，还是我的测试格式不正确？谢谢

或者，这也应该有效:

res.body.should.have.property("name", "new_org");

另外，只是一个注释，但从逻辑上讲，我认为将其放在对 expects 的另一个调用中而不是在最终回调中是有意义的。这个函数也可以重复使用，所以我倾向于把它放在可以重复使用的地方:

var isValidOrg = function(res) {
  res.body.should.have.property("name", "new_org");
};

it("should create a new org with valid privileges and input with status 201", function(done) {
  request(app)
    .post("/orgs")
    .send({ name: "new_org", owner: "oldschool@aol.com", timezone: "America/New_York", currency: "USD"})
    .expect(201)
    .expect(isValidOrg)
    .end(done);
});

现在您可以想象您正在为 /orgs/:orgId 测试 GET，并且您可以重复使用相同的验证。
