Protractor Dynamic numer of test runs depened on count() result

Question

In my Protractor Test suite I have some problem with parametrizing number of tests .

  it('Login and Count', function () {
    PageObject.login();
    var number = element.all(by.something()).count().then(function(n){
      //here i have my number which i want to use to run next 'it' n times
     });
  });

  it('Run number '+ m,function () {
    PageObject.Run(m);
  })

My problem is that I am able to reach my count result only inside then block when promise is resolved. How to use that to execute second it as many times as i want ? I am not able to write this result to global variable.

Sorry I am JS newbie and async promises are still a hell for me

You can use global variables as described in this question on SE.

Wonder if you really want to store a value in a global variable. Each it() in Protractor is a test. Tests should be run in isolation from other tests. If tests are not isolated and depended on each other it could become harder and time consuming in the future to maintain them. Since one failing tests could block all other tests. Also you cannot expect all the it() functions to run in the order of the file, certainly when running tests in parallel this could become an issue.

Have a look at the AAA test pattern, your test would look something like this:

it('my test', function() {
  //ARRANGE
  PageObject.login();
  var number;
  element.all(by.something()).count().then(function(n){
    number = n;
  });

  //ACT
  //Loop and execute Run() number of times the element exists.
  for (step = 0; step < number; step++) {
    PageObject.Run(step);
  }

  //ASSERT
  expect(something).toEqual(something_else);

});
