I installed latest Ethereum Wallent and I connected on test network and I clicked on Start Mining (Testnet only), but nothing is happening. I still have 0 ETH in my account.
I'm not sure if it's bad a design or a bug, I have no idea if it works.
Also I've tried via console
2. in new console
I get this error
Error: etherbase missing: etherbase address must be explicitly specified at web3.js:3104:20 at web3.js:6191:15 at web3.js:5004:36 at <anonymous>:1:1
Not sure how to start miner to get some test ETHs
