有人在stackblitz项目示例中使用玩笑来进行角度单元测试吗?
谢谢!

我以前曾经这样做过,但是对于茉莉而言,并不是开玩笑。您可能要遵循并在其上构建:
添加依赖项:jasmine-core
和@types/jasmine
。
添加/src/global-jasmine.ts
文件:
import jasmineRequire from 'jasmine-core/lib/jasmine-core/jasmine.js';
window.jasmineRequire = jasmineRequire;
编辑/src/styles.scss
并添加:
@import 'jasmine-core/lib/jasmine-core/jasmine.css';
添加/src/main-testing.ts
文件(在main.ts
旁边)并粘贴以下内容:
import './global-jasmine'
import 'jasmine-core/lib/jasmine-core/jasmine-html.js';
import 'jasmine-core/lib/jasmine-core/boot.js';
import './polyfills';
// This file is required by karma.conf.js and loads recursively all the .spec and framework files
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy.js';
import 'zone.js/dist/sync-test';
// Requires 'zone.js/dist/proxy.js' and 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import { getTestBed } from '@angular/core/testing';
import {
BrowserDynamicTestingModule,
platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';
// stuff to test
import './app/app.component.spec.ts'
jasmine.getEnv().configure({random: false});
bootstrap();
function bootstrap () {
if (window.jasmineRef) {
location.reload();
return;
} else {
window.onload();
window.jasmineRef = jasmine.getEnv();
}
// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting()
);
}
创建示例单元测试/src/app/app.component.spec.ts
:
describe('Testing tests', () => {
it('should succeed', () => expect(true).toEqual(true));
it('should fail', () => expect(true).toEqual(false));
});
该文件将被运行,因为它已在main-testing.ts
的要测试的东西注释中列出。如果要测试其他文件,请相应地更改链接。
最后,要运行测试,请编辑angular.json
并更改行
"main": "src/main.ts",
到
"main": "src/main-testing.ts",
要再次运行该应用程序,请将其改回。
