I am unable to hit these lines of code even after I added some jest-mocks to my test folder. I am sure that I would have to do something like below, but how would I then hit it to verify what is inside the if statement?

     attributes: {
          apiName: "Wire"
     state: {
          c__mediaId: "mediaId"


          this.currentPageRefernce = currentPageReference;
          this.mediaId = this.currentPageRefernce.state.c__mediaId;
