Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files. 12 | 13 | ## Code scaffolding 14 | 15 | Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive/pipe/service/class/module`. 16 | 17 | ## Build 18 | 19 | Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build. 20 | 21 | ## Running unit tests 22 | 23 | Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io). 24 | 25 | ## Running end-to-end tests 26 | 27 | Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/). 28 | Before running the tests make sure you are serving the app via `ng serve`. 29 | 30 | ## Further help 31 | 32 | To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md). 33 | -------------------------------------------------------------------------------- /e2e/app.e2e-spec.ts: -------------------------------------------------------------------------------- 1 | import { LazyPage } from './app.po'; 2 | 3 | describe('lazy App', () => { 4 | let page: LazyPage; 5 | 6 | beforeEach(() => { 7 | page = new LazyPage(); 8 | }); 9 | 10 | it('should display message saying app works', () => { 11 | page.navigateTo(); 12 | expect(page.getParagraphText()).toEqual('app works!'); 13 | }); 14 | }); 15 | -------------------------------------------------------------------------------- /e2e/app.po.ts: -------------------------------------------------------------------------------- 1 | import { browser, element, by } from 'protractor'; 2 | 3 | export class LazyPage { 4 | navigateTo() { 5 | return browser.get('/'); 6 | } 7 | 8 | getParagraphText() { 9 | return element(by.css('app-root h1')).getText(); 10 | } 11 | } 12 | -------------------------------------------------------------------------------- /e2e/tsconfig.e2e.json: -------------------------------------------------------------------------------- 1 | { 2 | "extends": "../tsconfig.json", 3 | "compilerOptions": { 4 | "outDir": "../out-tsc/e2e", 5 | "module": "commonjs", 6 | "target": "es5", 7 | "types":[ 8 | "jasmine", 9 | "node" 10 | ] 11 | } 12 | } 13 | -------------------------------------------------------------------------------- /karma.conf.js: -------------------------------------------------------------------------------- 1 | // Karma configuration file, see link for more information 2 | // https://karma-runner.github.io/0.13/config/configuration-file.html 3 | 4 | module.exports = function (config) { 5 | config.set({ 6 | basePath: '', 7 | frameworks: ['jasmine', '@angular/cli'], 8 | plugins: [ 9 | require('karma-jasmine'), 10 | require('karma-chrome-launcher'), 11 | require('karma-jasmine-html-reporter'), 12 | require('karma-coverage-istanbul-reporter'), 13 | require('@angular/cli/plugins/karma') 14 | ], 15 | client:{ 16 | clearContext: false // leave Jasmine Spec Runner output visible in browser 17 | }, 18 | files: [ 19 | { pattern: './src/test.ts', watched: false } 20 | ], 21 | preprocessors: { 22 | './src/test.ts': ['@angular/cli'] 23 | }, 24 | mime: { 25 | 'text/x-typescript': ['ts','tsx'] 26 | }, 27 | coverageIstanbulReporter: { 28 | reports: [ 'html', 'lcovonly' ], 29 | fixWebpackSourcePaths: true 30 | }, 31 | angularCli: { 32 | environment: 'dev' 33 | }, 34 | reporters: config.angularCli && config.angularCli.codeCoverage 35 | ?
