与噶角测试:"模块没有定义" [英] Angular testing with Karma: "module is not defined"

本文介绍了与噶角测试:"模块没有定义"的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我知道这个问题已经被问了很多次,我知道,在大多数情况下,人们缺少角mocks.js 文件。

我遇到了同样的问题,试图在模块上测试工厂。不幸的是,我一直运行到的问题与测试(为什么,角,哦,为什么你必须承担起窗口文件反对呢?),其中指出模块没有定义。我不知所措。我使用angular.mocks.module也尝试过,但后来我得到一个消息,说是没有定义的角。我在做什么错了?

值得注意的是,我使用一饮而尽作为任务亚军。我gulpfile(尚不完善,任务不链接):

  VAR一饮而尽=要求('吞掉'),    丑化=要求('咕嘟咕嘟-丑化),
    jshint =要求('一饮而尽-jshint'),
    茉莉=要求('一饮而尽-茉莉'),
    业力=要求('一饮而尽 - 卡玛),    路径= {
        剧本:剧本/ * JS
        规格:投机/ * JS
        DIST:DIST
    };gulp.task('prepare',函数(){
    返回gulp.src(paths.scripts)
        .pipe(jshint())
        .pipe(jshint.reporter(默认))
        .pipe(丑化())
        .pipe(gulp.dest(paths.dist))
});gulp.task(测试,函数(){
    gulp.src([paths.scripts,paths.spec])
        .pipe(因果报应({
            CONFIGFILE:karma.conf.js',
            动作:'运行'
        }));
});gulp.task('默认',['$ P​​ $ ppare','测试']);

我karma.conf.js,业力的init产生:

  //噶配置
//生成于星期五2014年3月14日14时24分三十秒GMT-0400(EDT)module.exports =功能(配置){
  config.set({    将用于解决所有的模式//基本路径(如文件,排除)
    基本路径:'',
    //框架使用
    //可用的框架:https://npmjs.org/browse/keyword/karma-adapter
    框架:['茉莉'],
    //的文件/目录模式在浏览器中加载
    文件:
      ./lib/angular/angular.min.js',
      ./lib/angular-mocks/angular-mocks.js',
      ./src/*.js',
      ./spec/*.js
    ]
    //文件的列表中排除
    排除:    ]
    // preprocess他们服务到浏览器之前匹配的文件
    //用preprocessors:https://npmjs.org/browse/keyword/karma-$p$pprocessor
    preprocessors:{    },
    //测试结果记者使用
    //可能的值:点,进步
    //可用记者:https://npmjs.org/browse/keyword/karma-reporter
    记者:进步]
    // Web服务器端口
    端口:9876,
    //使输出/禁止的颜色(记者和日志)
    颜色:真,
    //日志记录级别
    //可能的值:config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    LOGLEVEL:config.LOG_INFO,
    //启用/禁用看文件和执行测试,只要任何文件更改
    autoWatch:假的,
    //启动这些浏览器
    //浏览器可发射:https://npmjs.org/browse/keyword/karma-launcher
    浏览器:['铬'],
    //持续集成模式
    //如果为真,噶捕捉浏览器,运行测试,退出
    singleRun:假的
  });
};

最后,我的测试套件(没有的成立是,如果我可以通过这个障碍,我们会好):

  / *试验memento.js。 * /描述(纪念核心测试套件',函数(){
    VAR纪念品;    beforeEach(模块('备忘录'));    beforeEach(函数(){
        注(功能(_memento_){
            纪念= _memento_;
        });
    });    //检查功能。
      //检查,看看是否有预期的功能
    它('应该与预期接口',函数(){
        期待(angular.isFunction(memento.canUndo))TOBE(真)。
        期待(angular.isFunction(memento.canRedo))TOBE(真)。
        期待(angular.isFunction(memento.undo))TOBE(真)。
        期待(angular.isFunction(memento.redo))TOBE(真)。
        期待(angular.isFunction(memento.push))TOBE(真)。
    });    它('应该初始化',函数(){
        this.fail(错误(测试未实现'));
    });    它('应推动()改变的对象,函数(){
        this.fail(错误(测试未实现'));
    });    它('不应该推()不变的对象,函数(){
        this.fail(错误(测试未实现'));
    });    它('应在撤销原返回对象(),()的函数{
        this.fail(错误(测试未实现'));
    });    它('应该返回修改的对象上重做()',函数(){
        this.fail(错误(测试未实现'));
    });    它('不应该撤消()如果在堆栈的开始',函数(){
        this.fail(错误(测试未实现'));
    });    它('不应该重做()如果在栈底',函数(){
        this.fail(错误(测试未实现'));
    });    // TODO:实现恢复原来,清除历史记录。
    //
    //它('应该还原返回种子对象(),()的函数{
    // this.fail(错误(测试未实现'));
    //});    //它('应该清楚明确()栈',函数(){
    // this.fail(错误(测试未实现'));
    //});
});

有谁看到什么出错?我不知道是否有东西真的很明显我错过了 - 我可以用一组额外的眼睛,还是很多的。我本来以为我能够运行这是一个简单的茉莉花测试套件没有噶,但由于棱角分明,有问题。如果我不能得到这个工作,我可能只是用故宫的角包,并改变我的角模块,这样就支持CommonJS的...

谢谢大家!希望我是不是疯了。

编辑:我包括我的devdependencies

 devDependencies:{
    吞掉:〜3.5.6
    咕嘟咕嘟-丑化:〜0.2.1
    吞掉-jshint:〜1.5.0
    吞掉-茉莉花:〜0.2.0
    角度:〜1.2.10,
    报应:〜0.12.0
    吞掉-报应:0.0.4
    卡玛 - 茉莉花:〜0.2.2
    报应 - 铬 - 发射:〜0.1.2
  }


解决方案

该消息指出模块/角没有定义意味着你的角mocks.js文件不被加载,尽管你拥有了它在所列的事实,你的karma.conf.js文件。

您遇到的问题是一饮而尽 - 卡玛忽略你的karma.conf.js文件数组。当你通过一个字符串或水珠进入gulp.src在gulpfile发生这种情况。

要解决这个问题,通过gulp.src一个字符串虚假文件,./foobar来说,这将导致文件数组中的karma.conf.js文件来代替。

  gulp.task(测试,函数(){
  gulp.src('./ FOOBAR')
    .pipe(因果报应({
      CONFIGFILE:karma.conf.js',
      动作:'运行'
    }));
});

希望这有助于!

I know this question has been asked many times, and I know that in most cases people are missing the angular-mocks.js file.

I'm running into the same issue, attempting to test a factory on a module. Unfortunately, I keep running into issues with the tests (why, Angular, oh why must you assume a window and document object?), which state that module is not defined. I'm at a loss. I've also tried using angular.mocks.module, but then I get a message saying Angular isn't defined. What am I doing wrong?

Of note, I'm using gulp as a task runner. My gulpfile (not yet perfect, tasks aren't linked):

var gulp = require('gulp'),

    uglify = require('gulp-uglify'),
    jshint = require('gulp-jshint'),
    jasmine = require('gulp-jasmine'), 
    karma = require('gulp-karma'),

    paths = {
        scripts: "scripts/*.js",
        spec: "spec/*.js",
        dist: "dist"
    };

gulp.task('prepare', function () {
    return gulp.src(paths.scripts)
        .pipe(jshint())
        .pipe(jshint.reporter('default'))
        .pipe(uglify())
        .pipe(gulp.dest(paths.dist))
});

gulp.task('test', function () {
    gulp.src([paths.scripts, paths.spec])
        .pipe(karma({
            configFile: 'karma.conf.js',
            action: 'run'
        }));
});

gulp.task('default', ['prepare', 'test']);

My karma.conf.js, generated by karma init:

// Karma configuration
// Generated on Fri Mar 14 2014 14:24:30 GMT-0400 (EDT)

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'],


    // list of files / patterns to load in the browser
    files: [
      './lib/angular/angular.min.js',
      './lib/angular-mocks/angular-mocks.js',
      './src/*.js',
      './spec/*.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: false,


    // 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
  });
};

And finally, my test suite (nothing's set up yet, if I can pass this hurdle, we'll be good):

/* Tests for memento.js. */

describe('memento core test suite', function () {
    var memento;

    beforeEach(module('Memento'));

    beforeEach(function() {
        inject(function(_memento_) {
            memento = _memento_;
        });
    });

    // Check functions.
      // check to see if it has the expected function
    it('should match expected interface', function () { 
        expect(angular.isFunction(memento.canUndo)).toBe(true);
        expect(angular.isFunction(memento.canRedo)).toBe(true);
        expect(angular.isFunction(memento.undo)).toBe(true);
        expect(angular.isFunction(memento.redo)).toBe(true);
        expect(angular.isFunction(memento.push)).toBe(true);
    });

    it('should initialize', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should push() a changed object', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should not push() an unchanged object', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should return original object on undo()', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should return modified object on redo()', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should not undo() if at beginning of stack', function () {
        this.fail(Error('Test not implemented'));
    });

    it('should not redo() if at end of stack', function () {
        this.fail(Error('Test not implemented'));
    });

    // TODO: Implement revert to original, clearing history.
    // 
    // it('should return seed object on revert()', function () {
    //  this.fail(Error('Test not implemented'));
    // });

    // it('should clear the stack on clear()', function () {
    //  this.fail(Error('Test not implemented'));
    // });
});

Does anyone see anything awry? I'm not sure if there's something really obvious I'm missing - I could use an extra set of eyes, or many. I originally thought I'd be able to run this as a simple Jasmine test suite without Karma, but due to Angular, that has problems. If I can't get this to work, I might just use npm's Angular package and alter my Angular module so that it supports CommonJS...

Thanks, everyone! Hope I'm not crazy.

Edit: I've included my devdependencies.

  "devDependencies": {
    "gulp": "~3.5.6",
    "gulp-uglify": "~0.2.1",
    "gulp-jshint": "~1.5.0",
    "gulp-jasmine": "~0.2.0",
    "angular": "~1.2.10",
    "karma": "~0.12.0",
    "gulp-karma": "0.0.4",
    "karma-jasmine": "~0.2.2",
    "karma-chrome-launcher": "~0.1.2"
  }

解决方案

The message stating that module/angular is not defined means that your angular-mocks.js file is not being loaded, despite the fact you have it listed in your karma.conf.js file.

The problem you're experiencing is gulp-karma ignoring your karma.conf.js files array. This happens when you pass a string or glob into gulp.src in the gulpfile.

To work around this, pass gulp.src a string for a bogus file, "./foobar" for instance, and this will cause the files array in the karma.conf.js file to be used instead.

gulp.task('test', function () {
  gulp.src('./foobar')
    .pipe(karma({
      configFile: 'karma.conf.js',
      action: 'run'
    }));
});

Hope this helps!
