=method runRedirected

Redirects STDOUT to a local variable, executes the given function (reference) and attaches
all supplied arguments. The return is the return of the called method.

This is useful to test functions which call the print function.

=cut
sub runRedirected{
  my $subRef = shift;
  my ($exitCode, $stdout) = runRedirectedAll($subRef, @_);
  return $exitCode;
}

=method runRedirectedAll

This method returns the exit code of the executed method and the output of stdout

=cut
sub runRedirectedAll{
  my $subRef = shift;
  my $stdout;
  my $result;
  {
    local *STDOUT;
    open STDOUT, '>', \$stdout
        or die "Cannot open STDOUT to a scalar: $!";
    $result = $subRef->(@_);
    close STDOUT
        or die "Cannot close redirected STDOUT: $!";
  }
  return ($result, $stdout);
