In our previous blog, we focused on how to build a MongoDB replica set under the Windows platform. Detailed Blog Address:
As space is limited in the previous article did not verify the results, in this blog we mainly test:
Through the Rs.status () command we can query to each node to run normally.
First, the data synchronization test
Insert on port 28011, 28012:

Second, fault adaptive testing
When the main library stops heartbeat at the time of Detection, 28012 elect itself as the main library, see below:
28012 the above can be inserted:
28011, it's still not plugged in.
