How to create a test with asset ownership? #fabric

luizck@...
 

Hi all,

We have a test case where multiple orgs can put assets into a blockchain, but only its "owner" can alter the asset's state. The owner is identified by the MspId of the transaction.
Is there a way to pass (or create) the context of the owner organization to the callback?

To illustrate:

module.exports.run = function() {
    let asset  = asset_array[count++];
    let tx = {
        'transaction_type': 'AlterAsset',
        'asset': asset.id
    };

    //contx must be the context of the owner of the asset.
    return bc.invokeSmartContract(contx, 'mychannel', '0', [tx], 100);
};

Regards,
Luiz

Hi Luiz,

 

check out the following pending PR and documentation about a new Fabric adapter, which is quite flexible regarding the dynamic registration of users (affiliations, attributes, choosing the TX submitter).

Adapter: https://github.com/hyperledger/caliper/pull/296

Documentation: https://github.com/hyperledger/caliper/pull/297
