Test RPC default Providers Services

[tabaktoni]

Motivation and Resolution

This issue #1058 motivated me to add a test for the default RPC version defined by lib and the default RPC version server by RPC.

This test does not ensure any security just print results.
Could we maybe add some CI warning or action for testing RPC versions?
We could set expectations in this two tests like

• we expect 0.7 as the default version from RPC on base route
• we expect 0.7 as the lib default version and all rpc should have 0.7 implemented

Some feedback @ivpavici @penovicp

RPC version (if applicable)

There are 42 commits, with 36 files impacted!
Where is the code related to this verification of rpc spec?

except for getBaseUrl(it) the test here and above are the same, so we can extract it maybe and send as param!

I agree... also am curious for more thoughts!

I think it's a good idea.

Might be worth considering doing this as a separate script since it would bypass the environment setup for the regular tests.

Just for information, Blast is responding to provider.getSpecVersion() with : 0.7.0-rc2

I understand that you want to check if all default networks (list hard coded in the project) are really using default_url_version.
All 4 url includes at the end the default_url_version :

starknet.js/src/constants.ts

Lines 75 to 82 in b3a2946

	SN_MAIN: [
	`https://starknet-mainnet.public.blastapi.io/rpc/${RPC_DEFAULT_VERSION}`,
	`https://free-rpc.nethermind.io/mainnet-juno/${RPC_DEFAULT_VERSION}`,
	],
	SN_SEPOLIA: [
	`https://starknet-sepolia.public.blastapi.io/rpc/${RPC_DEFAULT_VERSION}`,
	`https://free-rpc.nethermind.io/sepolia-juno/${RPC_DEFAULT_VERSION}`,
	],

Logically, it should be OK by definition, but it's never bad to verify.
But I don't understand why you want to check the rpc versions of the base urls ... as we are not using them.

This will be probably revised and done through CI
