I am trying to make tests using Karma and i am following Angulars own testing guide. Currently i am using the most basic test class but having issues running it.

The test class: 

describe('1st test',()=>{
it('true is true', ()=> expect(true).toBe(true)); });

When i run it using npm test i get the following error in the command prompt:

I have checked the file that it cannot find and it exists in the directory stated by the error so i have no clue what to do.

Those are 404 errors for XHR requests. It doesn't mean that the file does not exist in the file system but that it is not served by accessing that particular path. It is unlikely that your server serves the entire file system so you shouldn't be worried if the file exists there or not but if it is being served from a particular URL that your program is trying to access it from.

See the code examples in this answer for an example:

Here the socket.io.js file is referenced in HTML as:

<script src="/socket.io/socket.io.js"></script>

not as an absolute path in the file system, and not with a path including node_modules. Paths in the HTTP requests and paths in the file system are a different thing and 404 errors are HTTP-specific.
