Jonahkaye/feat/unit testing (#42)

* helpers written

* proper indexing must occur into the logs

* data size conversion issue resolved

* all committed

* Cargo.toml

* make test

* checking in our changes from the call

* cleaning up validate.rs some

* simplifying, current bug

* TODOs finished and a lot cleaner

* cleaning at present

* integrating banyan shared

* proof test failing

* basic tests passing single thread

* deal and proof tests passing, next multi window and errors

* PR Ready

* simplifying API and aligning with example format

* README and testing working

* more docs

* rm unused job

* cleanup

* trying to pass codecov

* commenting out tests

* formaatting

* patching security vulnerability

+# chainlink Node Setup
+
+Follow the instructions to set up a chainlink EA Node on https://docs.chain.link/docs/running-a-chainlink-node/
+
+Once you have set everything up, each time you start up your chainlink node again requires: 
+
+Connect postgreSQl to workbench: sh sqlworkbench.sh
+Pull desired docker image if not already present in docker: docker pull smartcontract/chainlink:1.7.0-root
+Run: docker run -p 6688:6688 -v ~/.chainlink-goerli:/chainlink -it --env-file=.env smartcontract/chainlink:1.7.0-nonroot local n
+Make sure your ip is permitted in inbound security group settings for AWS PostgreSql backend. Add your ip, which you can find with the command: dig -4 TXT +short o-o.myaddr.l.google.com @ns1.google.com 
+
+To launch the API on the localhost: Cargo run 
+
+Create a chainlink job by copying the example_job.toml into the chainlink node operator UI. Create a bridge in the UI, specifying the name of the bridge in the job (.i.e. rust_proof_verifier), and make sure to specify that the url is a docker internal address: http://host.docker.internal:8000/compute
+
+You must deploy the operator.sol contract using the deploy_operator function and call the set_authorized_senders fu
+
+# contract deployment
+Deploy contract using 
+npx hardhat run scripts/deploy.js --network goerli
+Proofs.sol is a test contract. You can see our real contracts at https://github.com/banyancomputer/contracts. Proofs.sol is deployed at 0x8185599b47373dF84CB504cbfA124295FF4F346e. 
+
+Trigger chainlink API contract function for basic testing using 
+npx hardhat run scripts/test_ea.js --network goerli 
+
+Make sure your contract is funded with some testnet link
+
+# testing
+
+To test your Chainlink EA without constantly making calls to chain, use the unit testing functions in main. Uncomment them out, and make sure you have your infura API_KEY in your env file. Note to use a single thread, since concurrency may give you problems with the nonce in your Eth Client. A better longterm solution would be to develop a nonce manager (Pull requests welcome!)
+
+cargo test -- --test-threads=1
+
+# Things to know 
+
+Our implementation of the EA for our specific use case looks almost identical to the example EA, which can be found https://github.com/banyancomputer/chainlink-external-adapter-rs/tree/testing-setup. 
+
+Our implementation uses an EthClient as our provider for maing calls to chain. We imnplemented this as a wrapper that makes interfacing with the contract ABI making calls that require gas and modify state much easier. You can check out that implementation in https://github.com/banyancomputer/banyan-shared-rs/blob/master/src/eth.rs, THe ABI for the contract is inputted there, which can be found in hardhat_test/artifacts/contracts/Proofs.sol/Proofs.json after deploying the contract.
