may be you are missing to call get_logger in the main script. try this one:

use strict;
use warnings;
use Log::Log4perl;

my $logging_level = 'DEBUG';

my $conf = q(                                                         
+                                  
            log4perl.rootLogger = ).$logging_level.q(, logApp
            
            log4perl.appender.logApp = Log::Log4perl::Appender::File  
+       
            log4perl.appender.logApp.mode = append
            log4perl.appender.logApp.filename = 917173_test.log       
+               
            log4perl.appender.logApp.layout = Log::Log4perl::Layout::P
+atternLayout 
            log4perl.appender.logApp.layout.ConversionPattern   = %m %
+n
       );
       
Log::Log4perl->init( \$conf );                                        
+                                  
my $logger = Log::Log4perl->get_logger(); 
$logger->info("outer");
testPackage::foo(); 
$logger->info("outer");

package testPackage;

use Log::Log4perl qw(get_logger);
sub foo {
    my $logger = Log::Log4perl->get_logger();  # IF I PUT testLog IN T
+HE QUOTES THEN I'M GETTING THE blah IN THE CALLERS LOGS FILE
    $logger->info("inner");
}
1;

this produces following output:
