invoke

fn invoke(contract_address: felt252, function_name: felt252, calldata: @Array::<felt252>) -> Result::<(), RevertedTransaction> nopanic;

Invokes a contract's function. function_name parameter should be provided as a short string. invoke can mutate the state of the contract and does not return a value to query the contract for values use call.

Example

use result::ResultTrait;
use array::ArrayTrait;

#[test]
fn test_invoke() {

    let contract_address = 123;

    let mut calldata = ArrayTrait::new();
    calldata.append(10);
    calldata.append(11);
    calldata.append(12);

    invoke(contract_address, 'function_name', @calldata).unwrap();

    // ...
}
