TrialChain mock

How to build

• stack build builds the project
• stack build --test builds and runs tests
• stack exec trialchain-mock-exe runs the application

Testing requests

Let's send several requests to make sure it works as expected. First of all we have to build and run our application via stack build && stack exec trialchain-mock-exe. The command runs the server with initial random balances (which include 3 predefined addresses: abcdef, 10bcaf and abdffe0123). After server has been run, it greets with message like this:

Initial balances
{
  abcdef: 100
, 10bcaf: 200
, abdffe0123: 300
}

Where keys are addresses, and values are corresponding balances.

Let's send the first transaction, which transfers 50 coins from abcdef to 10bcaf:

curl -X POST -H "Content-Type: application/json" \
-d '{"id": 1, "rawTx": "0300000000000000abcdef00000000030000000000000010bcaf320000000100000000000000aa0100000000000000bb"}' \
localhost:8080/api/broadcast

As response we have to receive:

{"result":"f153076407d147fb7c78d39ccfd9564431672336e556bcd0f1acc7b6bed7bab5","id":1}

where f153076407d147fb7c78d39ccfd9564431672336e556bcd0f1acc7b6bed7bab5 is the transaction id.

Let's check that this transaction really exists now:

curl -X GET -H "Content-Type: application/json" \
-d '{"id": 1, "txId": "f153076407d147fb7c78d39ccfd9564431672336e556bcd0f1acc7b6bed7bab5"}' \
localhost:8080/api/get_tx

As response we have to receive:

{"result":"0300000000000000abcdef00000000030000000000000010bcaf320000000100000000000000aa0100000000000000bb","id":1}

where result is equal to rawTx from the first request.

Let's send one more transaction, 50 coins from abcdef to abdffe0123:

curl -X POST -H "Content-Type: application/json" \
-d '{"id": 2, "rawTx": "0300000000000000abcdef010000000500000000000000abdffe0123320000000100000000000000aa0100000000000000bb"}' \
localhost:8080/api/broadcast

Server response has to be:

{"result":"3c0fbf1be1c6f7a75e5fdd5f2683a052c3e982cb96bac2ce84f20628f43d3576","id":2}

Since this moment abcdef is out of money.

Let's request this transaction:

curl -X GET -H "Content-Type: application/json" \
-d '{"id": 1, "txId": "3c0fbf1be1c6f7a75e5fdd5f2683a052c3e982cb96bac2ce84f20628f43d3576"}' \
localhost:8080/api/get_tx

Expectedly, server response is:

{"result":"0300000000000000abcdef010000000500000000000000abdffe0123320000000100000000000000aa0100000000000000bb","id":1}

Let's try to request non-existing transaction:

curl -X GET -H "Content-Type: application/json" \
-d '{"id": 1, "txId": "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"}' \
localhost:8080/api/get_tx

Server's response:

{"error":"Tx #aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa not found.","id":1}

And as last request, let's try to transfer 1 coin from abcdef to abdffe0123:

curl -X POST -H "Content-Type: application/json" \
-d '{"id": 3, "rawTx": "0300000000000000abcdef020000000500000000000000abdffe0123010000000100000000000000aa0100000000000000bb"}' \
localhost:8080/api/broadcast

Server has to reject this transaction with message because abcdef is out ouf money:

{"error":"Balance of abcdef is -0, what is less than required amount 1.","id":3}
