用业力和browerify提供二进制数据

标签： karma-runner browserify karma-jasmine

我正在使用karma + jasmine + browserify来运行我的测试。

如果我尝试用业力来提供额外数据，我的测试就不再有效了，它告诉我“找不到变量：需要”。

如果我不尝试提供任何其他数据，它会按预期工作。

我如何使用browserify提供数据？

如果我删除“{pattern：'app / data / dcm / fruit'，包含：false，watched：false，serve：true}”，在以下配置文件中，“require”不再是未定义的，但当然我无法访问我希望我的测试加载的数据。

karma.conf：

// Karma configuration
// Generated on Tue Apr 14 2015 09:16:02 GMT+0200 (CEST)
'use strict';

module.exports = function(config) {
  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', 'browserify'],

    // list of files / patterns to load in the browser
    files: [
      'app/**/*.test.js',
      {pattern: 'app/data/dcm/fruit', included: false, watched: false, served: true}
    ],

    // list of files to exclude
    // exclude: [
    //   'app/doc/**/*.js',
    //   'app/examples/**/*.js'
    // ],

    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
      'app/**/*.test.js': ['browserify']
    },

    browserify: {
      debug: true,
      transform: [ 'glslify', 'babelify' ]
    },

    // 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_DEBUG,

    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: false,

    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['PhantomJS'],

    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: true
  });

虚拟测试文件：

/* globals describe, it, expect, beforeEach*/
'use strict';

var vjsParsersDicom = require('../parsers/parsers.dicom.js');

var datasets = [];
// fruit dataset
var data = {
  name: 'fruit',
  url: 'base/data/dcm/fruit',
  nbOfFrames: 60
};
datasets.push(data);

// for(var i=0; i<datasets.length; i++){
      var i = 0;
  describe('Parsing ' + datasets[i].name, function() {

    // before each, load the data...
    var dataset;
    beforeEach(function(done) {

      window.console.log(datasets[i].url);
      // fetch the data!
      var oReq = new XMLHttpRequest();
      oReq.open('GET', datasets[i].url, true);
      oReq.responseType = 'arraybuffer';

      oReq.onload = function (oEvent) {
        var arrayBuffer = oReq.response; // Note: not oReq.responseText
        if (arrayBuffer) {
          dataset = vjsParsersDicom.parseArrayBuffer(arrayBuffer);
          done();
        }
      };
      oReq.send(null);
    });


    it('contains expected number of frames', function() {
      expect(true).toBe(true);
    });
  });
// }

答案 0 :(得分：0)

Karma对我试图服务的东西感到困惑。 我们必须更加具体地了解所服务的数据。

此外，Karma无法提供任意二进制数据，如DICOM（.dcm）。首先，我们必须将.dcm文件重命名为.dcm.tar。

似乎我们只能提供文件，所以要提供我应该使用的所有文件：

files: [
      'app/**/*.test.js',
      {pattern: 'app/data/**/*', included: false, watched: false, served: true}
    ]

并仅提供具有指定扩展名的文件：

files: [
      'app/**/*.test.js',
      {pattern: 'app/data/**/*.dcm.tar', included: false, watched: false, served: true}
    ]
