I'm using Angular 7. I wrote a real simple test 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"];

and then a real simple Jasmine spec, src/app/pastebin.spec.ts, to test it, 

/* pastebin.spec.ts */

//import the Pastebin class
import { Pastebin } from './pastebin';

describe('Pastebin', () => {
    it('should create an instance of Pastebin',() => {
        expect(new Pastebin()).toBeTruthy();
    });

})

but when I go to run my tests, I get some errors that look like anything related to what I've done ...

Anyone know how I can approach this problem?

  • I tried running your code on my angular project and it was working fine. The problem seems to be something else. Can you do `xdescribe` and then `fdescribe` and let us know any difference in output – Shashank Vivek Aug 31 '19 at 03:42

    Maybe you have a broken installation of you node modules. Can you trying re-installing them? – lealceldeiro Sep 01 '19 at 16:40
  • @ShashankVivek, I tried running "xdescribe" but got the error "-bash: xdescribe: command not found". – Dave Sep 01 '19 at 16:43
  • @lealceldeiro, Are the re-install commands you suggest different than what's given in the answer? Those are the ones I just ran and got the error posted in the quesiton edit. – Dave Sep 01 '19 at 16:58

I've seen a very similar issue to this when running typescript @ 2.7.2 and @types/jasmine greater than 2.8.8 or jasmine >= 3.0.

Known safe working version for me is 

"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/platform-browser": "7.2.0",
    "@angular/platform-browser-dynamic": "7.2.0",
    "@angular/router": "7.2.0",
    "core-js": "2.5.4",
    "rxjs": "6.3.3",
    "tslib": "1.9.0",
    "zone.js": "0.8.26"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "0.13.0",
    "@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"
  }

If that isn't it please post your package.json. Some of the updated libraries require typescript 3.0, and if you don't have that you have to point to older versions.

Also I see that https://github.com/dfederm/karma-jasmine-html-reporter says For Jasmine < 3.0.0, use version 0.2.2, so you may also want to check that you have 

"karma-jasmine-html-reporter":"0.2.2"

  • Hi, I updated the versions to what you suggested (included my package.json in edit-3 to my question). I also included the error I get as a result -- "TypeError: env.catchExceptions is not a function" – Dave Sep 07 '19 at 17:30
  • Huh, that's interesting, as package.json indicates you're using Angular 5 when you say you're on Angular 7. I'm updating my answer to have the full dependency list for my angular 7 app that I know works. It has a higher version of typescript as well, which I think is what is going to fix what you're seeing. – Wesley Trantham Sep 07 '19 at 17:53
  • Also please note that I don't use `~` or `^` as these dependencies can be strange. I like exact versions for consistency. – Wesley Trantham Sep 07 '19 at 17:55
  • Thanks. I replaced my package.json's "dependencies" and "devDependencies" with what you have. Do I need to do something to install those before I run "ng test"? I ask because after I replaced those in package.json and ran "ng test" I still got these "HeadlessChrome 76.0.3809 (Mac OS X 10.13.6) ERROR, An error was thrown in afterAll, TypeError: env.catchExceptions is not a function" errors. – Dave Sep 08 '19 at 20:54
  • Oh yes, after you set those up just run `npm i` or `npm install`. Sometimes you need to delete package-lock.json first – Wesley Trantham Sep 09 '19 at 01:02
  • I should have mentioned how I approached fixing this when I encountered this a few months ago. I was upgrading jasmine and found the latest version gave me the error you originally saw. So then I started downgrading by typing in version numbers in package.json and running `npm i`. It took several tries, but I found the newest version of jasmine that I could use with the version of typescript I was locked into at the time as we were only on Angular 6. @Dave – Wesley Trantham Sep 09 '19 at 01:07

It seems like you are running Karma v2.0.5 which is a really outdated version of Karma.

30 08 2019 15:53:13.960:INFO [karma]: Karma v2.0.5 server started at http://0.0.0.0:9876/

If my memory serves me right, I had encountered this error before because I was running an outdated Karma with a more updated typescript or was it the other way around.

Anyway, the latest Karma test runner is V4.3.0.

You can upgrade your Karma and Jasmine by executing these commands:


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

If you have installed additional karma plugins, you'd probably want to update them too. Take a look at your package.json. For e.g. , you might have karma-firefox-launcher instead of chrome's version.

I did a simple search on my browser history and found this github issue: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/30310

This issue highlighted how they solved the problem by downgrading/upgrading their typescript to the support jasmine/karma version.

With trial-and-error and probably some researching, you'd most probably find a suitable combination of karma, jasmine and typescript versions that are compatible with each other in Angular 7.

However, I'd suggest that you simply upgrade your @angular/cli from Angular 7 to Angular 8 and update all of your karma and jasmine packages.

Angular 8 contains many breaking changes that resulted in many Angular 3rd party libs in updating all their libraries. Therefore, if you were to do a npm i some-lib in the future, it may not work with your Angular 7 project. And you'd have to find the last working version that works well with Angular 7. Upgrading to Angular 8 will save you a lot of these "downgrading" trouble. The latest karma and jasmine packages work with Angular 8 and it's much easier for you to just upgrade everything to the latest working versions.

  • Do note that github issue is almost a year old. And Angular 7 (which you mentioned is the version you are using in your question) supports typescript 3.1, I am not sure about typescript 2.8.4. That's why I suggested that you simply upgrade everything to the latest version =) – terahertz Sep 02 '19 at 03:37
  • Hey @Dave, looks like you had started a bounty =0... did you update to Angular 8 and it's still not resolved for you? Also, have a look at [this](http://dailydevfixes.blogspot.com/2018/11/angular-4-sudden-typesjasmine-error-at.html), maybe it'd help if you just remove the preceding symbols before jasmine packages? – terahertz Sep 03 '19 at 16:40
  • Unfortunately, in my current situation, upgrading to Angular 8 is not an option. I would like to see if there is a solution for Angular 7. Thanks for all your suggestions, though. – Dave Sep 03 '19 at 20:20
  • icic. I just saw your edit, seems like you managed to get karma running. But your jasmine version is probably too new/old, that's why a function couldn't be found. Check out this [github issue](https://github.com/ionic-team/ionic-unit-testing-example/issues/79#issuecomment-460706041), he managed to fix `TypeError: env.catchExceptions is not a function` for Angular 7 with a combination of lower versions of karma and jasmine. Anyway, if it doesn't help you to solve the issue, may I suggest that you edit in your package.json? – terahertz Sep 04 '19 at 02:46
  • i had the same issue during an project-update from angular 7 to 8. In my case i need to update karma-jasmine-html-reporter to the latest version (0.2.2 => 1.4.2). Maybe in your case you need to find a matching version. – deelde Sep 04 '19 at 12:10

It does not look like you wrap your test around a beforeEach to set up the Angular Testing Module. Can you try the code below:

    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();
    });

  })

  • Hi @Paul, I get two errors when I run your code. They are "ERROR in src/app/pastebin.spec.ts(7,14): error TS2304: Cannot find name 'async'. src/app/pastebin.spec.ts(8,5): error TS2304: Cannot find name 'TestBed'" – Dave Sep 05 '19 at 15:06
  • You can import this from @angular/core/testing. Hope this helps! – Paul Sep 06 '19 at 16:26
  • That solved the TestBed error but what about the async error? Still get the error, "error TS2304: Cannot find name 'async'." – Dave Sep 07 '19 at 17:34
  • Did you also import async from @angular/core/testing? – Paul Sep 07 '19 at 18:15
  • That solved the compilation error, but now the error that occurs when running the test itself is, "HeadlessChrome 76.0.3809 (Mac OS X 10.13.6) ERROR, An error was thrown in afterAll, TypeError: env.catchExceptions is not a function" – Dave Sep 08 '19 at 20:48
  • See if the link https://stackoverflow.com/questions/51543241/angular-6-unit-tests-an-error-was-thrown-in-afterall-nreferenceerror-cant-fin helps.... I think you can install karma-spec-reporter and add it to the karma.conf.js configuration to get better messages. – Paul Sep 09 '19 at 21:51
