试图使用supertest检查响应的主体 - 得到错误

Question

我正在尝试使用supertest进行一些测试.以下是我要测试的代码段:

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主体时遇到错误:

 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 Test.<anonymous> (../api/node_modules/supertest/node_modules/superagent/lib/node/index.js:133:10)
  at Test.EventEmitter.emit (events.js:96:17)
  at IncomingMessage.Request.end (../api/node_modules/supertest/node_modules/superagent/lib/node/index.js:703:12)
  at IncomingMessage.EventEmitter.emit (events.js:126:20)

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

这是supertest中的错误,还是我错误地格式化了我的测试？谢谢

Answer 1

或者,这也应该工作:

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

另外,只是一个注释,但从逻辑上讲,我认为将它放在另一个调用expects而不是最终回调中是有意义的.此函数也可以重复使用,因此我倾向于在可能的情况下将其放在可重用的位置:

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);
});

现在你可以想象你正在测试一个GETfor /orgs/:orgId,你可以重新使用相同的验证.

使用 Jest 这对我来说是这样的

  it('should do something', async () => {

    const test = await supertest(app)
      .post('/some/endpoint')
      .send({
        someResource,
      })
      .expect(200);

    expect(test.body.someKey).toBeDefined();
    expect(test.body.someKey).toBe('someValue');
  });

要测试响应正文，您只需将预期响应包含在 中expect，

const { describe, it } = require('mocha');
const supertest = require('supertest');
describe('Validate API calls', () => {
  it('create session post request should fail for invalid credentials', (done) => {
    const data = { user_name: 'incorrect_username', password: 'INVALID' };
    supertest(app).post('/api/session')
      .send(data)
      .expect('Content-Type', /json/)
      .expect({ name: 'AuthenticationError', message: 'Unauthorized' })
      .expect(401, done);
  });
});

这可以重写如下：

res.body.name.should.equal("new_org");

这将修复错误。
