为什么在 运行 一个简单的 Jasmine 测试时会出现 "error TS1005: ';' expected." 错误？
Why do I get a "error TS1005: ';' expected." error when running a simple Jasmine test?
我正在使用Angular7.我写了一个真正简单的测试class,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"];
然后是一个真正简单的 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();
});
})
但是当我去 运行 我的测试时，我得到了一些看起来与我所做的事情相关的错误...

看来你是 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 server started at http://0.0.0.0:9876/
如果我没记错的话，我之前遇到过这个错误，因为我是 运行 一个过时的 Karma 和更新的打字稿，或者是相反的方式。
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
如果您安装了额外的 karma 插件，您可能也想更新它们。看看你的 package.json。例如, 你可能有 karma-firefox-launcher 而不是 chrome 的版本。
我对我的浏览器历史记录进行了简单搜索，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 downgrading/upgrading 他们的打字稿解决问题到支持 jasmine/karma 版本。
通过反复试验和可能的一些研究，您很可能会在 Angular 7 中找到相互兼容的 karma、jasmine 和 typescript 版本的合适组合。
但是，我建议您只需将您的@angular/cli 从 Angular 7 升级到 Angular 8 并更新您所有的 karma 和 jasmine 包。
Angular 8 包含许多重大更改，导致许多 Angular 第 3 方库更新其所有库。因此，如果您将来要做 npm i some-lib，它可能不适用于您的 Angular 7 项目。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 "downgrading" 的麻烦。最新的 karma 和 jasmine 包与 Angular 8 一起使用，您只需将所有内容升级到最新的工作版本就容易得多。
您似乎没有围绕 beforeEach 包装测试来设置 Angular 测试模块。你能试试下面的代码吗:
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();
});
})
当 运行 typescript @ 2.7.2 和 @types/jasmine 大于 2.8.8 或 jasmine >= 3.0 时，我看到了与此非常相似的问题。
我已知的安全工作版本是
"dependencies": {
"@angular/animations": "7.2.0",
"@angular/common": "7.2.0",
"@angular/compiler": "7.2.0",
"@angular/core": "7.2.0",
"@angular/forms": "7.2.0",

},

"@angular/cli": "7.3.8",
"@angular/compiler-cli": "7.2.0",
"@angular/language-service": "7.2.0",
"@types/node": "8.9.4",
"@types/jasmine": "2.8.8",
"@types/jasminewd2": "2.0.3",
"codelyzer": "5.1.0",
"jasmine-core": "2.99.1",
"jasmine-spec-reporter": "4.2.1",
"karma": "4.1.0",
"karma-chrome-launcher": "2.2.0",
"karma-coverage-istanbul-reporter": "2.0.5",
"karma-jasmine": "2.0.1",
"karma-jasmine-html-reporter": "1.4.2",
"protractor": "5.4.2",
"ts-node": "7.0.0",
"tslint": "5.11.0",
"typescript": "3.2.2"
}
如果不是，请 post 您的 package.json。一些更新的库需要 typescript 3.0，如果你没有，你必须指向旧版本。
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有
"karma-jasmine-html-reporter":"0.2.2"
我正在使用Angular7.我写了一个真正简单的测试class,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"];
然后是一个真正简单的 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();
});
})

看来你是 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 server started at http://0.0.0.0:9876/
如果我没记错的话，我之前遇到过这个错误，因为我是 运行 一个过时的 Karma 和更新的打字稿，或者是相反的方式。
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
如果您安装了额外的 karma 插件，您可能也想更新它们。看看你的 package.json。例如, 你可能有 karma-firefox-launcher 而不是 chrome 的版本。
我对我的浏览器历史记录进行了简单搜索，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 downgrading/upgrading 他们的打字稿解决问题到支持 jasmine/karma 版本。
通过反复试验和可能的一些研究，您很可能会在 Angular 7 中找到相互兼容的 karma、jasmine 和 typescript 版本的合适组合。
但是，我建议您只需将您的@angular/cli 从 Angular 7 升级到 Angular 8 并更新您所有的 karma 和 jasmine 包。
Angular 8 包含许多重大更改，导致许多 Angular 第 3 方库更新其所有库。因此，如果您将来要做 npm i some-lib，它可能不适用于您的 Angular 7 项目。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 "downgrading" 的麻烦。最新的 karma 和 jasmine 包与 Angular 8 一起使用，您只需将所有内容升级到最新的工作版本就容易得多。
您似乎没有围绕 beforeEach 包装测试来设置 Angular 测试模块。你能试试下面的代码吗:
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();
});
})
当 运行 typescript @ 2.7.2 和 @types/jasmine 大于 2.8.8 或 jasmine >= 3.0 时，我看到了与此非常相似的问题。
我已知的安全工作版本是
"dependencies": {
"@angular/animations": "7.2.0",
"@angular/common": "7.2.0",
"@angular/compiler": "7.2.0",
"@angular/core": "7.2.0",

"protractor": "5.4.2",
"ts-node": "7.0.0",
"tslint": "5.11.0",
"typescript": "3.2.2"
}
如果不是，请 post 您的 package.json。一些更新的库需要 typescript 3.0，如果你没有，你必须指向旧版本。
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有
"karma-jasmine-html-reporter":"0.2.2"
