I wonder if we can test SDKs with this framework.

For example, I could create a JavaScript CLI (using iroha-javascript) with the same interface as iroha_client_clihas. Then it would be straightforward to plug it intoclient_cli.py`, passing just a different binary path.

First of all, it will ensure that JS or whatever SDK covers the same functionality for sure. Furthermore, building such a CLI using JS SDK will help to enhance the SDK itself, because it still doesn't have "real-word" use cases.

I have number of failed tests when i try to run testing suit.

@astrokov7 do we need to restart iroha before running tests?

[Erigara]

Looks good in general.

no

In the inteerest of time preservation it's better to fix this upstream.
