you don't need click on field open dialogue box.

opening dialogue box 'breaking' test.

just send keys directly input element, are, , click on ever button 'upload' button.

  driver.findelement(by.xpath("//input[@type='file']")).sendkeys("/path/to/file");   driver.findelement(by.id("id of upload button")).click();
