[Vuejs]-How to verify window.location.href in jest tests

Due to jsdom#unimplemented-parts-of-the-web-platform, and we know from this issue: window.location.href can’t be changed in tests.

We need make a little change for the code, here is the solution:

index.ts:

import { StudentServices } from './StudentServices';

export class PornClass {
  private errorMessage: string = '';
  constructor(private studentId: string) {}

  public async mounted() {
    return StudentServices.getCollegeurl(this.studentId)
      .then(response => {
        // window.location.href = response.data.collegeurl;
        Object.defineProperty(window, 'location', {
          value: {
            href: response.data.collegeurl
          }
        });
      })
      .catch(response => {
        this.errorMessage = 'errr';
      });
  }
}

StudentServices.ts:

export class StudentServices {
  public static async getCollegeurl(id: string) {
    return {
      data: {
        collegeurl: 'real url'
      }
    };
  }
}

index.spec.ts:

import { PornClass } from './';
import { StudentServices } from './StudentServices';

jest.mock('./StudentServices.ts', () => {
  const mockedStudentServices = {
    getCollegeurl: jest.fn()
  };
  return {
    StudentServices: mockedStudentServices
  };
});

describe('PornClass', () => {
  describe('#mounted', () => {
    it('should get college url and redirect correctly', async () => {
      const studentId = '1';
      const collegeurl = 'http://github.com/mrdulin';
      const p**n = new PornClass(studentId);
      (StudentServices.getCollegeurl as jest.MockedFunction<
        typeof StudentServices.getCollegeurl
      >).mockResolvedValueOnce({ data: { collegeurl } });

      await p**n.mounted();
      expect(StudentServices.getCollegeurl).toBeCalledWith(studentId);
      expect(window.location.href).toBe(collegeurl);
    });
  });
});

Unit test result with coverage report:

 PASS  src/stackoverflow/56482707/index.spec.ts
  PornClass
    #mounted
      ✓ should get college url and redirect correctly (8ms)
