user1151: I'm trying to test to see if transactions went through or not and blockchain.info is super helpful for this on the real network.

user2716: Coinprism.info has a testnet blockchain explorer. It does colored coins as well.
Note that the SSL certificate is self signed.

user4241: Bitpay's insight project supports and has a live version of the testnet.

user61230: I might be a little late to the game here, but blockchain.info do offer testnet resources for SegWit2x. Go to https://testnet5.blockchain.info and you'll see an identical site to the original, but with testnet coins.

user323: TestNet Bitcoin Block Explorer appears to be not working too well at the moment. However, BTCLook does appear to be supporting TestNet and looks like a good alternative.

user12525: Your could also use Biteasy.com Testnet Block Explorer which is pretty fast and also includes a REST API.

user12004: Blockr.io now also supports Bitcoin TESTNET

user15209: www.blocktrail.com/tBTC now supports testnet too and has an API for it too (including wallet API)
