Question

以下有效：

describe('My App', function() {
  describe('when logged in', function() {
    it('should allow registered user to make a thing', function(done) {
      agent.post('/make-a-thing')
      .auth('testusername', 'validuserpass')
      .send({thingName:'mythingname'})
      .expect(201)
      .end(function(err, res) {
        if (err) return done(err);
        res.body.should.have.property('thingUrl').and.to.match(/thing\/[0-9a-f]+$/);
        done();
      });
    });
  });
});

现在，如果我想在“登录时”块中添加越来越多的测试，我不想每次都重复.auth('testusername', 'validuserpass')行。我应该将auth代码放在beforeEach中，因为这就是beforeEach的用途。

所以我尝试了这个：

describe("My App", function() {

  describe('when logged out', function() {
    it('should disallow anonymous user from doing things', function(done) {
      agent.post('/do-things')
      .send({thingName:'mythingname'})
      .expect(403)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  });

  describe('when invalid user', function() {
    beforeEach(function(done) {
      agent.auth('invalidusername', 'invaliduserpass');
      done();
    });

    it('should disallow unrecognized user from doing things', function(done) {
      agent.post('/do-things')
      .send({thingName:'mythingname'})
      .expect(403)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  })

  describe('when logged in', function() {
    beforeEach(function(done) {
      agent.auth('testusername', 'validuserpass');
      done();
    });

    it('should allow registered user to make a thing', function(done) {
      agent.post('/make-a-thing')
      .send({thingName:'mythingname'})
      .expect(201)
      .end(function(err, res) {
        if (err) return done(err);
        res.body.should.have.property('thingUrl').and.to.match(/thing\/[0-9a-f]+$/);
        done();
      });
    });

    it('should require name attribute to create a thing', function(done) {
      agent.post('/make-a-thing')
      .send({notaname:'notathingname'})
      .expect(409)
      .expect('Content-Type', /json/)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  });

});

agent.auth未定义的情况。我认为auth方法是在auth.post。

的结果中定义的

有办法做到这一点吗？

为了记录，这是我为解决这个问题所做的。我修改了supertest的代理对象和 Request 原型。代理现在有一个名为 auth 的方法，它会导致 Request.end 在结束之前先调用 auth ，然后恢复< em> Request.end 回到原来的状态。

configure.js

var app = require('app'),
    supertest = require('supertest');

// global
agent = supertest.agent(app);

(function(Request) {
  'use strict';

  (function(_end) {
    agent.auth = function() {
      var authArgs = arguments;
      Request.end = function() {
        var endArgs = arguments;
        var endResult = _end.apply(this.auth.apply(this, authArgs), endArgs);
        Request.end = _end;
        return endResult;
      };
      return agent;
    };
  })(Request.end);
})(agent.post('').constructor.prototype);

APP-test.js

describe("My App", function() {

  describe('when logged out', function() {
    it('should disallow anonymous user from doing things', function(done) {
      agent.post('/do-things')
      .send({thingName:'mythingname'})
      .expect(403)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  });

  describe('when invalid user', function() {
    beforeEach(function(done) {
      agent.auth('invalidusername', 'invaliduserpass');
      done();
    });

    it('should disallow unrecognized user from doing things', function(done) {
      agent.post('/do-things')
      .send({thingName:'mythingname'})
      .expect(403)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  })

  describe('when logged in', function() {
    beforeEach(function(done) {
      agent.auth('testusername', 'validuserpass');
      done();
    });

    it('should allow registered user to make a thing', function(done) {
      agent.post('/make-a-thing')
      .send({thingName:'mythingname'})
      .expect(201)
      .end(function(err, res) {
        if (err) return done(err);
        res.body.should.have.property('thingUrl').and.to.match(/thing\/[0-9a-f]+$/);
        done();
      });
    });

    it('should require name attribute to create a thing', function(done) {
      agent.post('/make-a-thing')
      .send({notaname:'notathingname'})
      .expect(409)
      .expect('Content-Type', /json/)
      .end(function(err, res) {
        if (err) return done(err);
        done();
      });
    });
  });

});

我的测试是这样运行的，所以首先执行 configure 脚本：

mocha tests/configure.js tests/*-test.js

在describe块中的每个测试之前的agent.auth
