even more problems working with files [obsolete]

Hello again,

it might not be related to my previous post which is why I created another one.

StorageFile.read() seems to always expect a length argument - but how do I then read a whole file? there is no size method?

But there is another problem: when I try

const Storage = require('Storage');
  function compareFileWith (expectedContent) {
    let readText = Storage.open('4testing','r').read(1000);­
    if (readText != expectedContent) {
      print('>>>> file does not look as expected');
      print('>>>> expected "' + expectedContent + '"');
      print('>>>> got "' + readText + '"');
    }
  }

/**** create file ****/

  if (Storage.write('4testing','Hello, World!')) {
    print('file "4testing" was successfully created');
  } else {
    print('file "4testing" could not be created');
  }
  compareFileWith('Hello, World!');
print('finished');

the file "4testing" is successfully created - but reading it using StorageFile.read produces a strange result:

file "4testing" was successfully created
>>>> file does not look as expected
>>>> expected "Hello, World!"
>>>> got "4testing4testing4testing"
finished

What am I doing wrong?

BTW: I am using the "cutting edge" distribution of today
