Blockchain Development with Hyperledger

Testing the Invoke method

It's now time to define the test for the Invoke function. In line 7 of the following codeblock, checkInit is called to initialize the ledger, followed by checkInvoke in line 13, which invokes the requestTrade function. The requestTrade function creates a new trade asset and stores it on the ledger. To verify that the ledger contains the correct state, a new TradeAgreement is created and serialized in lines 15 and 16, before a new composite key is calculated in line 17. Finally, in line 18, the state of the key is verified against the serialized value.

Additionally, as previously outlined, our chaincode contains a series of functions that together define the trade workflow. We will chain the invocations of these functions ...
