It's not an error, it's a failed test. That's because you don't call the log function in your example, so the test "correctly" fails.

describe('Hello world', function () {
  it('says hello', function () {
    spyOn(console,'log').and.callThrough();
    comp.helloWorld();
    expect(console.log).toHaveBeenCalled();
  });
});
