为什么我在运行简单的 Jasmine 测试时会出现“错误 TS1005:预期为‘;’”错误?
我正在使用 Angular 7。我编写了一个非常简单的测试类 src/app/pastebin.ts,
export class Pastebin {
id: number;
title: string;
language: string;
paste: string;
constructor(values: Object = {}) {
Object.assign(this, values);
}
}
export const Languages = ["Ruby","Java", "JavaScript", "C", "Cpp"];
然后编写了一个非常简单的 Jasmine 规范 src/app/pastebin.spec.ts 来测试它,
/* pastebin.spec.ts */
//import the Pastebin class
import { Pastebin } from './pastebin';
describe('Pastebin', () => {
it('should create an instance of Pastebin',() => {
expect(new Pastebin()).toBeTruthy();
});
})
但是当我运行测试时,我收到一些错误,这些错误看起来与我所做的事情有关...

我在运行 typescript @ 2.7.2 和 @types/jasmine 大于 2.8.8 或 jasmine >= 3.0 时看到了与此非常相似的问题。
对我来说,已知安全的工作版本是

}
如果不是,请发布您的 package.json。一些更新的库需要 typescript 3.0,如果您没有,则必须指向旧版本。
我还看到 https://github.com/dfederm/karma-jasmine-html-reporter 说 对于 Jasmine < 3.0.0,使用版本 0.2.2,因此您可能还需要检查您是否拥有
"karma-jasmine-html-reporter":"0.2.2"
看起来您正在运行 Karma v2.0.5,这是一个非常过时的 Karma 版本。
30 08 2019 15:53:13.960:INFO [karma]: Karma v2.0.5 服务器已在 http://0.0.0.0:9876/ 启动
如果我没记错的话,我之前遇到过这个错误,因为我运行的是过时的 Karma 和更新的 typescript,或者是相反的情况。
无论如何,最新的 Karma 测试运行器是 V4.3.0 。
您可以通过执行以下命令升级您的 Karma 和 Jasmine:
npm install karma@latest --save-dev
npm install karma-jasmine@latest karma-chrome-launcher@latest jasmine-core@latest --save-dev
npm install @types/jasmine@latest --save-dev
如果您安装了其他 karma 插件,你可能也想更新它们。看看你的 package.json。例如,你可能有
karma-firefox-launcher
而不是 chrome 的版本。
我在浏览器历史记录中进行了简单搜索,发现了这个 github 问题: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/30310
这个问题强调了他们如何通过将他们的 typescript 降级/升级到支持 jasmine/karma 版本来解决问题。
通过反复试验和一些研究,你很可能会找到在 Angular 7 中相互兼容的 karma、jasmine 和 typescript 版本的合适组合。
但是,我建议你只需将 @angular/cli 从 Angular 7 升级到Angular 8 并更新所有 karma 和 jasmine 包。
Angular 8 包含许多重大更改,导致许多 Angular 第三方库更新其所有库。因此,如果您将来要执行
npm i some-lib
,它可能无法与您的 Angular 7 项目一起使用。而且您必须找到与 Angular 7 配合良好的最后一个工作版本。升级到 Angular 8 将为您省去很多“降级”麻烦。最新的 karma 和 jasmine 包与 Angular 8 配合使用,您只需将所有内容升级到最新的工作版本即可。
看起来您没有将测试包装在 beforeEach 周围来设置 Angular 测试模块。您可以尝试以下代码吗:
describe('MyComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
// All the components referenced in the test
],
providers: [
// All injected services
]
})
.compileComponents();
}));
it('should create an instance of Pastebin',() => {
expect(new Pastebin()).toBeTruthy();
});
})
