Streaming replication is designed to let the master run properly when a
standby disconnects.

Yes.

Now something that has been mentioned by the others: isn't your standby
here for a reason? Like in case of failure don't you have a process to
failover automatically? Perhaps you are shooting yourself in the foot by
unplugging this standby, hence you should, and other recommend the same,
simply let the existing standby alone and create a new instance by taking a
new base backup from either the master or the standby and use it for your
tests. Then eliminate the node you created. In short: avoid doing stupid
things...
