如何使用 Jasmine 节点加载文件进行测试?

2022-01-11 00:00:00 bdd jasmine javascript

我有一个简单的 JavaScript 文件 color.js 和一个匹配的规范文件 colorSpec.js.

I have a simple JavaScript file, color.js, and a matching spec file, colorSpec.js.

color.js:

function Color() 
{

}

colorSpec.js:

require('./color.js');

describe("color", function() {
  it("should work", function() {
    new Color(255, 255, 255);
  });
});

当我运行 jasmine-node colorSpec.js 时,我得到以下异常:

When I run jasmine-node colorSpec.js, I get the following exception:

ReferenceError: Color is not defined

如何让 Jasmine 在运行 colorSpec.js 之前加载我的 color.js 文件?

How can I get Jasmine to load my color.js file before running colorSpec.js?

推荐答案

您可以使用 require() 在 colorSpec.js 中加载您的 color.js.如果你不告诉茉莉花它们在你的规范文件中到底是什么,我看不出茉莉花是如何猜测所有依赖关系的.编辑 :一个快速而肮脏的解决方案,但也许有一些内置的 Jasmine 可以做到这一点:

you could load your color.js in the colorSpec.js with a require(). I dont see how jasmine can guess all the dependencies without you telling jasmine what they are exactly in your spec file. Edit : A quick and dirty solution , but maybe there is something builtin Jasmine to do that :

fs = require('fs')
myCode = fs.readFileSync('./color.js','utf-8') // depends on the file encoding
eval(myCode)

那么你的课程应该可以与 jasmine 一起使用

then your class should be available with jasmine

如果你直接在你的文件上调用 require 我认为你需要创建一个模块并导出它

if you call require directly on your file i think you need to create a module and export it
