[英]Using Reporters with Mocha on Node.js
As my username implies, I'm brand new to Node. 顾名思义,我是Node的新手。 I really like a lot of the ideas. 我真的很喜欢很多想法。 I'm just trying to get started with learning it. 我只是想开始学习它。 One of the things I'm looking to understand is how to setup a test driven environment with Node. 我想了解的一件事是如何使用Node设置测试驱动的环境。
Currently, I have a basic javascript file called ToTest.min.js. 当前,我有一个名为ToTest.min.js的基本javascript文件。 This file defines a class called ToTest, which exposes a method called getItems. 该文件定义了一个名为ToTest的类,该类公开了一个名为getItems的方法。 To test this method, I've written the following code in Test.js: 为了测试此方法,我在Test.js中编写了以下代码:
var should = require("should");
var toTest = require("../ToTest.min.js");
describe('ToTest.js', function () {
describe('test1', function () {
var t = new ToTest();
var items = t.getItems();
console.log("Result: " + items.length);
t.should.have.length(1);
});
});
I execute this file from the command line via: 我从命令行通过以下方式执行此文件:
mocha Test.js
When its executed, I see the following output: 执行后,我看到以下输出:
Result: 0
C:\Projects\MyProject\node_modules\sh
ould\lib\should.js:130
throw err;
^
AssertionError: expected [] to have a length of 1 but got 0

How do I get a reporter working so that the results of the unit tests are formatted better? 如何让记者工作,以便更好地格式化单元测试的结果? I tried 我试过了
mocha Test.js -R dot
and I received the same result. 我收到了相同的结果。
Ah, you need to use the it
function for actual tests, not describe
. 嗯,您需要将it
函数用于实际测试,而不要describe
。
var should = require("should");
var toTest = require("../ToTest.min.js");
describe('ToTest.js', function () {
it('test1', function () {
var t = new ToTest();
var items = t.getItems();
console.log("Result: " + items.length);
t.should.have.length(1);
});
});
