How to use bitcoin testnet wallet I have a simple use case. 


  I want to send some testnet coins to my testnet wallet and be able to
  see it in bitcoin-core in testnet mode


What I did so far: 1. Go to File-->Receiving address. Setup a new reciving address here
2. Go to website providing free testnet coins and send it the address that I set in step 1.
3. Wait until the transaction is confirmed.

Questions:
I expect to see the above transactions in the bitcoin UI. Eg. If I click on 'Overview' button, I expect to see those testnet bitcoins. Similarly, under 'Transactions', I see nothing. Could somebody point out what is going wrong here?
Thanks to Nate, the quite possible reason is that since my bitcoin core is still synchronizing, it would not have seen the transaction.

Will await for this to complete. Thanks again, Nate!
