Requirements

• The tests works on OS/X. Should work in Linux. May work in Windows with Cygwin
• Geth/v1.9.14-stable/darwin-amd64/go1.14.2 running with the Byzantium fork switched on
• Solc 0.6.8+commit.0bbfe453.Darwin.appleclang

---

Executing The Tests

• Run geth in dev mode

  ./00_runGeth.sh
  

• Run the test in 01_test1.sh

  ./01_test1.sh
  

• See test1results.txt for the results and test1output.txt for the full output.

Notes

• The tests were conducted using bash shell scripts running Geth/v1.9.14-stable/darwin-amd64/go1.14.2 JavaScript commands
• The smart contracts were compiled using Solidity 0.6.8+commit.0bbfe453.Darwin.appleclang
• The test script can be found in 01_test1.sh
• The test results can be found in test1results.txt with details in test1output.txt
• The test can be run on OS/X, should run on Linux and may run on Windows with Cygwin
• The genesis.json allocates ethers to the test accounts, and specifies a high block gas limit to accommodate many transactions in the same block
• The 00_runGeth.sh scripts starts geth with the parameter --targetgaslimit 994712388 to keep the high block gas limit
• The reasons for using the test environment as listed above, instead of truffles/testrpc are:
  • The test are conducted using the actual blockchain client software as is running on Mainnet and not just a mock environment like testrpc
  • It is easy to change parameters like dates, addresses or blocknumbers using the Unix search/replace tools
  • There have been issues in the part with version incompatibility between testrpc and solidity, i.e., version mismatches
  • The intermediate and key results are all saved to later viewing
