Demo project for testing thousands of transactions for smart contracts.

It needs:

• Truffle 4.0.3
• Ganache-cli v6.1.0-beta.0 (see this release notes)

The project contains a very dummy lottery (see contracts/Lottery.sol) and a bunch of tests.

How to run tests:

• Test_01_buy_5_tickets.es6 is the basic test. It can be run in truffle develop

• Test_02_buy_500_tickets_automining.es6 tries to by 500 tickets and needs ganache with automining and truffle console

• Test_03_buy_500_tickets_using_events.es6 tries to by 500 tickets and needs ganache with fixed block time and truffle console Number of tickets may be increased to 5K or 15K.

Running ganache with automining:

ganache-cli -m "candy maple cake sugar pudding cream honey rich smooth crumble sweet treat" -u 0 -u 1 --gasLimit 0x2FEFD800000 -a 100 --defaultBalanceEther 10000  > ganache.log

Running ganache with fixed block time:

ganache-cli -m "candy maple cake sugar pudding cream honey rich smooth crumble sweet treat" -u 0 -u 1 --gasLimit 0x2FEFD800000 -a 100 --defaultBalanceEther 10000 --blocktime 5 > ganache.log 

PS Do not forget to run npm install to checkout all necessary deps before running tests.
