Test local wallet

1. open examples
2. run node testWallet.js
3. you can see mnemonic and simple password and 10 accounts imported

Test with Harmony node

First you have to run harmony's test node.

1. git clone

   git clone git@github.com:harmony-one/harmony.git
   

2. follow the Build all executables instruction, here

3. open your editor, inside core/resharding.go , edit GenesisShardSize = 50 to GenesisShardSize = 5

4. use this script to run

   ./test/deploy.sh ./test/configs/ten-oneshard.txt
   

Wait for the test-node running for 30 seconds,

Then open another console , go back to our Harmony-sdk-core/examples folder,

Run:

node testNode.js

Test with ganache-cli

** ganache-cli runs in js file **,

In this case, we use ganache and ethereum's setting to simulate the result

We don't need harmony's testnode running.

1. open examples
2. run node testGanache.js
