用于单元测试POST请求的npm软件包是什么？

Question

It will have to have the option to set the req.params of POST request.

supertest package doesn't provide this or it is not well documented to be clear it does.

Answer 1

If you are testing an express application, supertest supports POST as well as most other HTTP methods. The express req.params is populated by the path portion of the URL, so you would do something like

var app = require('./my-app')
var request = require('supertest')(app)

request.post('/some/path/req/params/is/here?some=query')
  .send({some: 'body'})
  .expect(200)
  .end(function (error, res) {
    assert(res.body.something === 'value')
  })

Answer 2

Yes you can with super test, since it has the same actions as superagent , this is an example:

request
  .post('/api/pet')
  .send({ name: 'Manny', species: 'cat' })
  .set('X-API-Key', 'foobar')
  .set('Accept', 'application/json')
  .end(function(err, res){
    // Calling the end function will send the request 
  });

By default sending strings will set the Content-Type to application/x-www-form-urlencoded, multiple calls will be concatenated with &, here resulting in name=tj&pet=tobi:

request.post('/user')
    .send('name=tj')
    .send('pet=tobi')
    .end(callback);

Answer 3

The supertest docs say:

Anything you can do with superagent, you can do with supertest

Therefore, the following should work fine:

request(app)
.post('/')
.query({format: 'json'})
.expect(....)
