<p>I'm doing integration tests with Emulation
As far as I understand under emulation wallets have initial funds.</p>
<p>Example:</p>
<pre><code>test :: IO ()
test = runEmulatorTraceIO $ do
    let 
        w1 = knownWallet 1
        walletAddress = mockWalletAddress w1
        # how to get utxos for walletAddress under emulator ????
