摩卡测试没有出现

我正在使用Node&amp ;;进行 Web开发。快递,第5章(质量保证)。我已经设置了Mocha和Chai,但测试没有出现,即使我将?tests = 1添加到网址上。

meadowlark.js(主要入口点):

var express = require('express');
var app = express();
var handlebars = require('express-handlebars').create({ defaultLayout: 'main' });

// express handles normalizing url

app.set('port', process.env.PORT || 3000);
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');
app.use(express.static(__dirname + '/public'));

app.use(function(req, res, next) {
   res.locals.showTests = app.get('env') !== 'production' && req.query.text === '1';
   next();
});

app.get('/', function(req, res) {
   res.render('home');
});

app.get('/about', function(req, res) {
   res.render('about');
});

// 404 catch-all handler (middleware)
app.use(function(req, res) {
   res.status(404);
   res.render('404');
});

// 500 error handler (middleware)
app.use(function(err, req, res, next) {
   console.error(err.stack);
   res.status(500);
   res.render('500');
});

app.listen(app.get('port'), function() {
   console.log('Express started on http://localhost:' + app.get('port') + '; press Ctrl-C to terminate.');
});

main.handlebars(主模板):

<!DOCTYPE html>

<html>

<head>
   <title>Meadowlark Travel</title>
   {{#if showTexts}}
      <link rel="stylesheet" href="/vendor/mocha.css">
   {{/if}}
<script src="http://code.jquery.com/jquery-3.0.0.js" integrity="sha256-jrPLZ+8vDxt2FnE1zvZXCkCcebI/C8Dt5xyaQBjxQIo=" crossorigin="anonymous"></script>
</head>
<body>
   <header><img src="/img/logo.png" alt="Meadowlark Travel logo"></header>
   {{{body}}}

   {{#if showTests}}
      <div id="mocha"></div>
      <script src="/vendor/mocha.js"></script>
      <script src="/vendor/chai.js"></script>
      <script>
         mocha.ui('tdd');
         var assert = chai.assert;
      </script>
      <script src="/qa/tests-global.js"></script>
      {{#if pageTestScript}}
         <script src="{{pageTestScript}}"></script>
      {{/if}}
      <script>mocha.run();</script>
   {{/if}}
</body>
</html>

public / qa / tests-global.js(摩卡测试的位置):

suite('Global Tests', function() {
   test('page has a valid title', function() {
      assert(document.title && document.title.match(/\S/) &&  
         document.title.toUpperCase() !=== 'TODO');
   }); 
});

文件夹结构:

meadowlark.js
node_modules > *node.js/npm*
package.json
public > qa     > tests-global.js
       > vendor > chai.js,
                > mocha.css,
                > mocha.js
views > home.handlebars
      > layouts > main.handlebars

我做错了什么,我怎样才能让Mocha测试显示出来?如果您需要任何其他文件,请询问。

答案 0 :(得分:2)

您有两个拼写错误和一个语法错误。

meadowlark.js中,将req.qurey.text更改为req.query.test

app.use(function(req, res, next) {
   res.locals.showTests = app.get('env') !== 'production' && req.query.test === '1';
   next();
});

main.handlebars中,将{{#if showTexts}}更改为{{#if showTests}}

{{#if showTests}}
  <link rel="stylesheet" href="/vendor/mocha.css">
{{/if}}

public/qa/tests-global.js中,not-equals运算符应为!==而不是!===

test('page has a valid title', function() {
  assert(document.title && document.title.match(/\S/) &&  
    document.title.toUpperCase() !== 'TODO');
});
