Question

我正在使用因果报应茉莉花做单元测试，我正在尝试做我的第一次测试。我在这里使用第一个例子： https://jasmine.github.io/1.3/introduction.html#section-Matchers

它似乎没有做任何事情，所以我添加了一些日志记录并试图让它捕获错误：

console.log('a');
describe("A suite", function() {
    console.log('b', typeof(it));
    it("contains spec with an expectation", function() {
        console.log('c');
        expect(true).toBe(false);
    });
});

这就是我的输出结果：

Chrome 43.0.2357 (Mac OS X 10.10.3) LOG: 'a'

Chrome 43.0.2357 (Mac OS X 10.10.3) LOG: 'b', 'function'

所以看起来“it”函数内部没有任何内容被执行，因为'c'永远不会被输出。我错过了什么吗？

更新所以这是我正在运行的艰巨任务：

module.exports = function (grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        karma: {
            unit: {
                configFile: 'karma.conf.js'
            }
        }
    });

    grunt.loadNpmTasks('grunt-karma');
    grunt.registerTask('default', ['karma']);
};

这是我的package.json，其中包含已安装的npm包列表：

  }
}

最后，这是我的karma.conf.js

module.exports = function(config) {
  var package = require('./package.json')
  console.log(package.configs.client_javascript_paths);
  config.set({
    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',
    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine', 'requirejs'],

    // list of files / patterns to load in the browser
    files: package.configs.client_javascript_paths.concat([
            'public/components/**/*.tests.js'
    ]),
    // list of files to exclude
    exclude: [
    ],
    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
    },
    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter
    reporters: ['progress'],
    // web server port
    port: 9876,
    // enable / disable colors in the output (reporters and logs)
    colors: true,
    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,
    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,
    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome'],
    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false
  });
};

我只是跑

 grunt

启动它以使输出位于此顶部。

由于requirejs框架与karma一起使用，因此发生了这种情况。如果你不需要它，那么你可以从karma.conf.js中删除它，测试就可以了。但如果您确实需要它，那么我建议您查看此documentation page，说明如何为requirejs配置karma，它实际上需要一个额外的文件。

使用您在问题中提供的文件，我可以在执行以下步骤后执行测试：

首先创建karma.conf.js
使用CLI命令karma init重新启动karma config

Do you want to use Require.js ?

Yes

选择Do you wanna generate a bootstrap file for RequireJS?

Yes

从备份中复制了所有内容，并将karma init生成的文件（应该称为test-main.js）添加到已监视文件列表中：

module.exports = function(config) {
    var package = require('./package.json');
    config.set({

        // ...

        files: package.configs.client_javascript_paths.concat([
            'public/components/**/*.tests.js',
            'test-main.js', // here it is
        ])

        // ...

    });
};

“它（）”似乎陷入了茉莉花测试
