[MINOR] Fix locale specific NumberFormatException in testutils …

Change Logs

String.format is locale specific. Example:

if (Locale.getDefault() == ENGLISH) {
  assert String.format("%5f", 0.1f) == "0.100000"
}
if (Locale.getDefault() == GERMAN) {
  assert String.format("%5f", 0.1f) == "0,100000"
}

So default GERMAN locale leads to failure of new BigDecimal("0,100000") with exception NumberFormatException.
It is not convenient to develop when we have locale specific tests.

Impact

Fix NumberFormatException when default locale consists of comma as decimal separator
