不包括karma.js中的带有幻影和angular2的文件夹

Question

当我试图用幻影运行业力测试时，如果我有另一个node_modules的例子的话，我就有问题了。

例如：

MyComponent
└── node_modules
└── examples
    └── node_modules
    └── src
        └── app
            └── app.component.ts
            └── app.component.html
            └── app.component.css
            └── app.component.spec
            └── app.module.ts
        └── assets
        └── index.html
        └── angular-cli.json
        └── karma.conf.js
        └── package.json
└── src
    └── app
        └── my.component.ts
        └── my.component.html
        └── my.component.css
        └── my.component.spec.ts
    └── assets
    └── base.spec.ts
    └── karma.conf.js
    └── package.json

package.json

    "@angular/common": "2.4.9",
    "@angular/compiler": "2.4.9",

    "karma-typescript-angular2-transform": "1.0.0-beta.5",
    "karma-phantomjs-launcher": "1.0.4"
  }

karma.conf.js

module.exports = function(config) {
    config.set({

        frameworks: ["jasmine", "karma-typescript"],

        files: [
            { pattern: "base.spec.ts" },
            { pattern: "src/app/**/*.+(ts|html)" }
        ],

        exclude: [
            'examples/**/*.js',
            'examples/**/*.ts'
        ],

        preprocessors: {
            "**/*.ts": ["karma-typescript"]
        },

        karmaTypescriptConfig: {
            bundlerOptions: {
                entrypoints: /\.spec\.ts$/,
                transforms: [
                    require("karma-typescript-angular2-transform")
                ]
            },
            coverageOptions: {
                instrumentation: true
            }
        },

        reporters: ["progress", "karma-typescript"],

        browsers: ["Chrome"]
    });
};

当我在没有示例文件夹的情况下运行测试时，一切都正常，但是如果我尝试使用内部的示例来运行测试，而忽略它，它就无法工作。

我得到了下一个错误：

14 03 2017 11:15:07.881:错误因果报应：(/workspace/node_modules/typescript/lib/typescript.js:25122:46)：TypeError:无法读取未定义的属性“名称”在/workspace/node_modules/typescript/lib/typescript.js:25146:21 at Map.forEach at mergeSymbol Map.forEach(原生)

Answer 1

我发现你错了。

我必须排除预处理器配置中的文件夹：

     `karmaTypescriptConfig: {             bundlerOptions: {                 entrypoints: /\.spec\.ts$/,                 transforms: [                     require("karma-typescript-angular2-transform")                 ]             },             coverageOptions: {                 instrumentation: true             },             exclude: ['examples']         },`
