Question

我正试图在Karma中运行Jasmine测试。这是针对使用RequireJS的AngularJS应用程序，但目前，测试是一个简单的expect(true).toBe(true);测试，没有Angular依赖。我发现它在禁用Karma的requirejs模块并在"client/app/require-shared.js"中注释"test/require-test.js"和files并直接加载testSpec.js文件时运行。

但是，只要我重新启用requirejs并将RequireJS配置文件添加回karma.conf.js的files - 保持testSpec.js文件在那里“静态”加载 - 我看到了错误

Chrome 33.0.1750 (Windows 7) ERROR
  Uncaught TypeError: Cannot read property 'failedCount' of null
  at C:/.../project/node_modules/karma-jasmine/lib/adapter.js:126
Chrome 33.0.1750 (Windows 7) ERROR
  Uncaught TypeError: Cannot read property 'length' of null
  at C:/.../project/node_modules/karma-jasmine/lib/jasmine.js:2518
Chrome 33.0.1750 (Windows 7): Executed 1 of 2 ERROR (0.009 secs / 0.001 secs)

如果我尝试完整的Angular测试，我会得到关于$injector为空的错误，但我认为这完全是因为这个requirejs模块问题。在我的设置中我缺少什么来使这项工作？

测试/ karma.conf.js

module.exports = function(config) {

    config.set({
        basePath: "../", // resolves to "project/"

        frameworks: ["jasmine", "requirejs"],

        files: [
            // load the RequireJS config files first
            "client/app/require-shared.js",
            "test/require-test.js",

            // set included to false for files to be loaded via RequireJS
//          {pattern: "bower_components/**/*.js", included: false},
//          {pattern: "client/**/*.js",           included: false},
//          {pattern: "test/unit/*Spec.js",       included: false}
            {pattern: "test/unit/*Spec.js"}
        ],


        // list of files to exclude
        exclude: [
//          "client/app/app.js",
//          "client/app/bootstrap.js",
//          "client/app/require-main.js",
            "*.conf.js"
        ],

        reporters: ["progress"],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: false,
        browsers: ["Chrome"],
        singleRun: true
    });
};

        var normalPath = pathToModule(file);
        console.log("adding " + file + " as " + normalPath + " to allTestFiles array");
        allTestFiles.push(normalPath);
    }

requirejs.config({
    baseUrl: "/base/client/components/"

    /*
     * "path" is defined in require-shared.js and shared with

Answer 1

问题在于TEST_REGEXP生成的karma init在文件名中查找了spec或test。这导致 require-test.js 文件作为测试规范被引入。

解决方案是

之一

重命名require-test.js
将(spec|test)更改为RE

spec

将RE更改为/^(?:(?!require-test\.js$).)*(spec|test)\.js$/i（另请参阅this answer）

这也可能是您的问题的原因，因为它在备用情况下报告相同的错误（缺少package.json）：https://github.com/tkellen/js-matchdep/issues/11。但是，如果您看到此结果的错误消息，那么您将运行旧版本的npm。升级会给你一个不同的错误信息（根据线程）。
