Using 'Typeof' in Vue.js Testing to fix errors.

 

Using Chai in Vue.js - for some reason my test looked like this . 

it('Home page message', function(done) {

request('http://localhost:8080' , function(error, response, body) {

expect(body.$('div.app').text().to.have.string('Cornwall'));

done();

});

});

This was returning the error 

Uncaught TypeError: body.$ is not a function

To fix this wanted to see 'body' was, so added the code 

console.log(body)

The 'console.log' prints out in your terminal.  The print out looks like a string , and this can be confirmed with. 

console.log(typeof body)

From here on I can use 'search' on the string for the text I'm looking for . 

var expect = require('chai').expect;

var request = require('request');

it('Home page message', function(done) {

request('http://localhost:8080' , function(error, response, body) {

expect(body.search('Cornwall'));

done();

});

});

Additionally if you want to turn the 'body' into DOM objects then we can use 'jsdom'

I'll have a code example for this soon.
