Like I would do wget -O - http://blockchain.info/q/getblockcount 2>/dev/null for the main net.
How do I get testnet block height?

Blockchain.info does not track the testnet, but blockexplorer.com does. In fact the API you're using was originally from blockexplorer.com, and blockchain.info simply adopted it.
wget -O - http://blockexplorer.com/testnet/q/getblockcount 2> /dev/null
or shorter
curl http://blockexplorer.com/testnet/q/getblockcount

BlockExplorer doesn't work anymore for me (redirecting to testnet.blockexplorer.com which throws a 502) so I found a new alternative:

You have to get the "last_block" element.
