Today I stumbled upon an address. (https://blockchain.info/address/1E7DHcoz3FPtHzB9UJMxwrKSNymRxNCHU4)
There are already 69 transactions but all of them are of 0 BTC in value.

Moreover in every transactions there is one output stating "(Escrow 1 of 1xxxxxxxxx...1xxxxxxxxx...1xxxxxxxxx...)"

Are these transactions pushed by any automated bots to spam the network or are those transactions done for testing purpose?

maybe someone is trying out blockchain.info escrow feature (https://blockchain.info/wallet/escrow). first time I ever seen that.

After clicking on your link I got this message-

Insecure Alias. Please login using your wallet identifier link.

Is that an outdated page? Or have they closed down the escrow service?
But I think the recent transaction occurred on 2016-01-20.
So the transaction might be pushed from an external source.

Also I see something unusual in this ??? -- https://www.blocktrail.com/BTC/address/1E7DHcoz3FPtHzB9UJMxwrKSNymRxNCHU4/transactions
(Total balance is null but every transaction has a value of 0.00003000 BTC)

you have to enter your wallet identifier and password and log in. I just tried it and can't see anything about escrow. so yeah maybe it's something different.

You guys have got it all wrong. Anything after wallet/ is an identifi identifier alias. So in your wallet settings, you could set up an alias, maybe like "Monnt" (blockchain.info/wallet/Monnt, and it will automatically convert Monnt into my wallet identifier. There is no blockchain.info escrow service.

If you look at this https://blockchain.info/address/1Emkdpb5WKamvLNHpNknazTXWcCaqnQMNx receiving address,it seemed to have received all the transactions but its just not shown in the respective txid's.Maybe its for experimental purposes ? Not sure maybe should wait for expert to comment. 

LOL! Really you thing someone's alias can be "escrow"?
Besides why will he waste his time broadcasting potential null transactions?

I believe someone (solo pool maybe) is trying to validate those transactions itself in order to solve a block.
Or maybe something else is happening there!

Those transactions are using bare multisig, which blockchain.info is labeling as escrow. Bare multisig is the script of a p2sh address (a "normal" multisig address) except it is not an address and that script is placed in the output script.

Usually these are spam transactions for encoding data into the blockchain as few people actually use bare multisig for multisig transactions nowadays.
