How can I add a testnet wallet to my Binance account?

I have a Binance account with some real BTC in its wallets. I have created a testnet wallet in Binance Wallet Chrome extension and claimed some BNB, so now I have 1 BNB in the testnet wallet.

I'd like to develop some logic with Binance API and already generated API key and secret, but as far as I understand, the testnet wallet is not connected to my Binance account so far.

So, can I somehow import/connect the testnet wallet into my Binance account?
