茉莉花忽略打字稿测试文件？

Question

这是我第一次使用 Jasmine 制作项目，我正在学习教程，但马上就遇到了问题。

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

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

对于 Jasmine 打字稿。

现在我的 ./spec 文件夹中有一个测试文件，如下所示：

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));
      });
    });

  });

});

但是当我运行这个命令时：

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

我得到这个结果：

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

很明显我的测试文件被忽略了。或者也许我错过了一些图书馆？如果是这种情况，我会收到错误消息吗？这里的主要问题是我没有得到太多关于问题所在的方向，除了 Jasmine 由于某种原因似乎没有“看到”测试文件。

只是想推进我的项目。任何建议将不胜感激。

您的测试运行程序似乎不知道您正在尝试运行打字稿测试。您是否使用 Karma 作为测试运行器？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，如下所示。请密切注意对框架、文件和预处理器部分的添加。

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
    })
};
