Dinamic Tests on JEST

There is a way to create dynamic Tests on Jest based on a ASYNC function for example?

This code run without any error, but test('dynamic test') does not run, even it the conditional is true

var formObject;

describe('test1',()=>{
  beforeAll(() => {
    return promise().then(
      data => {
          formObject=retrieved_data;
      }
    );
  })

  test('test1',()=>{ 
    expect ...
  })

  test('test2',()=>{ 
    expect ...
  })

if(some conditional based on formObject){
  test('dinamic test',()=>{ 
    expect ...
  })
}

})
