Yes. The default values for a definition's (or class's) parameters cannot
safely draw on the values of other parameters of the same object. It is
therefore incorrect for the default value of the $testingDb parameter to
use the $hostSuffix parameter. I would write that definition something
like this, instead:
define testing1::instance (
$hostSuffix = 'NOTSET',
$testingDb = 'NOTSET'
) {
$realHostSuffix = $hostSuffix ? {
'NOTSET' => "-${environment}",
default => $hostSuffix
}
$realTestingDb = $testingDb ? {
'NOTSET' => "db1${realHostSuffix}${dnsDomainInt}",
default => $testingDb
}
# ... use $realHostSuffix and $realTestingDb ...
}
