Hello,
Please verify, to which registry URL testrunner is trying to connect. By default, it will try to connect to local registry url. If your registry is running on remote server, please add -m <Registry_URL> to Testrunner command and execute the test.
Ex: TestRunner -u admin -p admin -t C:\Devtest_10.1\DevTest10.1\examples\Tests\DevTest_config_info.tst -m tcp:\\Myhostname:2010\Registry -a
Thanks
Srikanth
