karma coverage - how to add values to FormGroup mock

Question

I'm trying to write a karma test for the following method

addNewRule() {
    let nameAdded = this.formRuletypeGroup.get('controlId').value;
    let typeAdded = this.formRuletypeGroup.get('type').value;

    console.log('nameAdded ----->', nameAdded );
    console.log('typeAdded ----->', typeAdded );

    if (nameAdded == '' || typeAdded == null) {
      return;
    }

}

How do I mock this in my test so that nameAdded and typeAdded will have values?

this is my attempt, but the values are always empty

 component.formTypeGroup= formBuilder.group({ 
      nameAdded : new FormControl('Test Name', Validators.required),
      typeAdded : ['Sir', Validators.required]
    });

when I look at the log from the ng test, I see the following:

HeadlessChrome 87.0.4280 (Windows 10.0.0): Executed 2 of 44 SUCCESS (0 secs / 0.447 secs)

LOG: '--------------nameAdded -------------->', ''

HeadlessChrome 87.0.4280 (Windows 10.0.0): Executed 2 of 44 SUCCESS (0 secs / 0.447 secs)

LOG: '--------------typeAdded -------------->', ''

Thanks in advance!
