Jasmine 2.0 SpecRunner vs Karma [英] Jasmine 2.0 SpecRunner vs Karma

问题描述

我刚开始使用Jasmine，我能够使用Html中的SpecRunner就好了。但是当我配置Karma时遇到了差异：

I just started using Jasmine and I was able to use the SpecRunner from the Html just fine. However when I configured Karma I encountered a discrepancy:

describe('Calculator', function(){
    var obj;
    beforeEach(function(){
        //initialize object
        obj = new Object();

        this.addMatchers({
            toBeFive: function () {
                return {
                    compare: function (actual, expected) {
                        return {
                            pass: actual === 5,
                            message: actual + ' is not exactly 5'
                        }
                    }
                };
            },

这段代码无法使用SpecRunner.html：

This piece of code does not work from the SpecRunner.html:

 this.addMatchers({

相反，我必须使用它：

 jasmine.addMatchers({

这是什么包括spe crunner：

This is what is include the specrunner:

 <!-- libs... -->
  <script type="text/javascript" src="lib/jasmine-2.0.0/jasmine.js"></script>
  <script type="text/javascript" src="lib/jasmine-2.0.0/jasmine-html.js"></script>
  <script type="text/javascript" src="lib/jasmine-2.0.0/boot.js"></script>

  <!-- source files here... -->
  <script type="text/javascript" src="../../calculator/calculator.js"></script>

  <!-- test files here... -->
  <script type="text/javascript" src="spec/calculator/calculator-test.js"></script>

我得到的错误是：

TypeError: Object #<Object> has no method 'addMatchers'

请注意，Karma没有错误但是如果我使用jasmine.addMatchers（ {它确实。

Please note that Karma raise no errors but if I use jasmine.addMatchers({ it does.

推荐答案

如果你运行 npm install karma-jasmine@~0.2.1 安装karma之后，这将使用正确的茉莉花版本（因为新适配器仅在几天前发布，因此默认情况下仍未更新karma以安装正确的版本）

If you run npm install karma-jasmine@~0.2.1 after installing karma this will use the correct jasmine version (karma still hasn't updated to install the right version by default as the new adapter was only released a few days ago)
