Is it possible to pass some number of block number during test script in between Txs?

During testing my script, in between transaction calls I want to pass N number of blocks on the ganache blockchain, if possible.

Populus had something as follows: chain.wait.for_block(100), but there is no chain object exist on brownie; is there any alternative object for the chain object?

print(web3.eth.blockNumber) # prints: 100
tx = token.setValue({'from': accounts[0]}) 
tx = token.setValue({'from': accounts[0]}) 
print(web3.eth.blockNumber) # prints: 100

tx = token.setValue({'from': accounts[0]}) 
print(web3.eth.blockNumber) # prints: 100
chain.wait.for_block(100) # I want to pass 100 blocks on the blockchain ...
print(web3.eth.blockNumber) # prints: 200
tx = token.setValue({'from': accounts[0]})

[Q] Does Brownie provide this, if yes how?

Brownie loads ganache-cli itself when it loads. If you already have ganache running, it won’t recognize that.

I need to document this behaviour and maybe make brownie check for a running copy of ganahe…

Yes, it’s possible using the rpc class: https://eth-brownie.readthedocs.io/en/latest/api.html#rpc

>>> web3.eth.blockNumber
1
>>> rpc.mine(100)
Block height at 100

It’s available in the immediately when you load the console. From a script, either from brownie import * or from brownie.network import rpc

Sorry the documentation on this is a bit lacking, I’m in the process of updating it!
