Integration testing

[devbugging]

Add integration testing that will setup all the EVM gateway components and engines and use the emulator and scripts to generate data, which will after the test is run be checked against the APIs to see if it was correctly handled.

To avoid conflicts with current work done on the main branch, we will first check the indexed data against storage APIs and then after getting the changes in the main, we will change querying to the RPC APIs.

We will have multiple test cases which will be able to run using a simple CLI comand: go run main.go --test {name} where the name of the test will select which case you want to run.
Initially we will just have a simple case where we submit couple of transactions to cause the block executed events as well as transaction executed events.

Below is a list of ready-to-use JSON-RPC calls for some endpoints.

eth_sendRawTransaction

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["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"],"id":1}'

The transaction above is a contract deployment for:

contract Multiply7 {
    event Print(uint);

    function multiply(uint input) returns (uint) {
        Print(input * 7);
        return input * 7;
    }
}

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xb88c02f88982029a01808083124f809499466ed2e37b892a2ee3e9cd55a98b68f5735db280a4c6888fa10000000000000000000000000000000000000000000000000000000000000006c001a0f84168f821b427dc158c4d8083bdc4b43e178cf0977a2c5eefbcbedcc4e351b0a066a747a38c6c266b9dc2136523cef04395918de37773db63d574aabde59c12eb"],"id":2}'

The transaction above will call the multiply function, with an input of 6

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xb88c02f88982029a02808083124f809499466ed2e37b892a2ee3e9cd55a98b68f5735db280a4c6888fa10000000000000000000000000000000000000000000000000000000000000007c080a0409f5baa7622655f76f7f67c1bd8cc4cdd5a8e64fab881d78c47d9d73e907befa04981b65452d66beeb80527f3e8d3d0bf18aa21cfbd9a0c5ee749192d43d72d95"],"id":3}'

The transaction above will call the multiply function, with an input of 7

eth_call

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_call","params":[{"from":"0x658bdf435d810c91414ec09147daa6db62406379","to":"0x99466ed2e37b892a2ee3e9cd55a98b68f5735db2","gas":"0x76c0","gasPrice":"0x9184e72a000","value":"0x0","input":"0xc6888fa10000000000000000000000000000000000000000000000000000000000000006"}],"id":4}'

The above JSON-RPC call with call the multiply function also, with an input of 6
Note: this is a read-only call, does not affect the blockchain state and does not raise any logs.

eth_getLogs

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_getLogs","params":[{"topics":["0x24abdb5865df5079dcc5ac590ff6f01d5c16edbc5fab4e195d9febd1114503da"]}],"id":5}'

The above JSON-RPC call will return the logs that match a given topic, which in this case searches for the Print event from the Multiply7 solidity contract.

eth_getTransactionCount

curl -XPOST 'localhost:8545/rpc' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_getTransactionCount","params":["0x658Bdf435d810C91414eC09147DAA6DB62406379","latest"],"id":6}'

The above JSON-RPC call will return the number of transactions for a given address.
