测试失败。详情请参阅上文

Question

尝试进行npm测试时，出现了此错误，但是我似乎无法修复该错误。几天来一直试图将我的头缠在mochajs和node.js上，但我似乎都无法使用travis ci来解决问题，]]

终端显示错误：

  1) "before all" hook in "{root}"
  2) "after all" hook in "{root}"

  0 passing (3ms)
  2 failing

  1) "before all" hook in "{root}":
     TypeError: app.listen is not a function
      at Context.<anonymous> (test/test.js:10:16)
      at processImmediate (internal/timers.js:456:21)

  2) "after all" hook in "{root}":
     ReferenceError: server is not defined
      at Object.stop (app.js:64:5)
      at Context.<anonymous> (test/test.js:37:21)
      at processImmediate (internal/timers.js:456:21)



npm ERR! Test failed.  See above for more details.
这是test.js文件

const assert = require('chai').assert;
const app = require('../app');
var server;

//Results
serverTestResult = app.serverTest();
dbTestResult = app.dbTest();

before(function(){
  server = app.listen(3000);
});

describe('App', function(){
  describe('serverTest()', function(done){
    it('sayHello should return server', function(){
      assert.equal(serverTestResult, 'running');
    });

    it('serverTest should return type string', function(){
      assert.typeOf(serverTestResult, 'string');
    });
  });

  describe('dbTest()', function(done){
    it('sayHello should return server', function(){
      assert.equal(dbTestResult, 'connected');
    });

    it('dbTest should return type string', function(){
      assert.typeOf(dbTestResult, 'string');
      done
    });
  });
});

after(async () => {
  require('../app').stop();
});
这是app.js文件中的一些代码段

module.exports = {
  serverTest: function() {
    return app.get("port");
  },
  dbTest: function() {
    return 'connected';
  },
  stop: function() {
    server.close();
  }
}

//routes
app.use("/", require("./routes/web"));
app.use("/api", require("./routes/api"));

app.set("port",process.env.PORT || 3000);
app.listen(app.get("port"),function(){
    console.log(module.exports.serverTest);
});
