茉莉花忽略打字稿测试文件？

Question

这是我第一次和Jasmine一起制作一个项目，我正在学习一个教程，但是马上就要解决问题了。

我已经安装了jasmine-node，typings和typescript。我也跑了：

typings install dt~jasmine --save-dev --global 

对于茉莉花打字稿。

现在，我有我的./spec文件夹中的测试文件看起来像这样：

import { async, ComponentFixture, TestBed } from '@angular/core/testing'; 
import { DatePickerComponent } from '../src/components/via-datepicker.component'; 
import * as moment from 'moment'; 

const Moment: any = (<any>moment).default || moment; 

describe('DatePickerComponent',() => { 
    let component: DatePickerComponent; 
    let fixture: ComponentFixture<DatePickerComponent>; 

    beforeEach(async(() => { 
    TestBed.configureTestingModule({ 
     declarations: [ DatePickerComponent ] 
    }) 
    .compileComponents(); 
    })); 

    beforeEach(() => { 
    fixture = TestBed.createComponent(DatePickerComponent); 
    component = fixture.componentInstance; 
    fixture.detectChanges(); 
    }); 

    it('should create',() => { 
    expect(component).toBeTruthy(); 
    }); 

    it('should open when clicked',() => { 
    fixture.debugElement.nativeElement.querySelector('body').click(); 
    fixture.whenStable().then(() => { 
     expect(component.opened); 
    }); 
    component.close(); 
    }); 

    describe('While open',() => { 
    beforeEach(() => { 
     component.open(); 
    }); 

    describe('Pressing the "Today\'s date" button',() => { 
     it('should set the value of the picker to the current date and close it',() => { 
     fixture.debugElement.nativeElement.querySelector('.datepicker-buttons button').click(); 
     expect(Moment().isSame(component.value, 'day') && Moment().isSame(component.value, 'month')); 
     expect(!component.opened); 
     }); 
    }); 

    describe('Clicking on a date',() => { 
     it('should change the value of the picker and close it',() => { 
     let oldValue: any = component.value; 
     fixture.debugElement.nativeElement.querySelectorAll('.day')[10].click(); 
     expect(!component.opened); 
     expect(!component.value.isSame(oldValue)); 
     }); 
    }); 

    }); 

}); 

但是当我运行此命令：

node_modules/jasmine-node/bin/jasmine-node spec 

我得到这样的结果：

Finished in 0 seconds 
0 tests, 0 assertions, 0 failures, 0 skipped 

很清楚我的测试文件被忽略。或者我错过了一些图书馆？如果出现这种情况，我会收到错误信息吗？这里的主要问题是我没有给出什么问题的方向，除了Jasmine由于某种原因似乎没有“看到”测试文件。

只是试图推进我的项目。任何建议将不胜感激。

看起来好像您的测试跑步者不知道您正在尝试运行打字稿测试。你是否在使用Karma作为测试跑步者？如果是这样，您需要将您的Typescript文件添加到您的karma.config文件并安装karma-typescript并配置您的karma.config文件，类似于下面显示的内容。密切关注对框架，文件和预处理器部分的补充。

karma.config

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', 'karma-typescript'], 


    // list of files/patterns to load in the browser 
    files: [ 
     { pattern: "app/tests/**/*.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: { 
     "app/tests/**/*.spec.ts": ["karma-typescript"] 
    }, 


    // 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: [], 

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