Angular karma unit test coverage branche

Question

I have a component with a @Attribute decorator as parameter. I did a test on it but sonar tells me that my builder’s line is not 100% covered on the branch. It highlights me 'green' in yellow. I would have liked to know how to cover it

export class CompStatusColorComponent{

  constructor(@Attribute('colorStatut') public colorStatut: string = 'green') { 
    this.colorStatut = colorStatut || 'green';
  }
  ngOnInit(): void {
  }

}

When the parameter colorStatut is undefined, it will be initialized with the default value 'green'. Therefore, beside providing a specific value, you'll probably also have to provide null for parameter colorStatut in order to obtain full test coverage.
