`truffle test` fails with 'out of gas' on all solidity tests

See original GitHub issue

I’ve asked for help in the Truffle Gitter before filing this issue.

Issue

Truffle v4.1.7 fails to run simple solidity test contract. Note that v4.1.6 works fine.

Steps to Reproduce

npm -g install truffle@4.1.7 Try to run test:

pragma solidity ^0.4.21;

import "truffle/Assert.sol";

contract Test {
  function testRun() {
  }
}

Expected Behavior

  Test
    ✓ testRun (51ms)


  1 passing (1s)

Actual Results

  Test
    1) "before all" hook: prepare suite


  0 passing (989ms)
  1 failing

  1) Test "before all" hook: prepare suite:
     Error: VM Exception while processing transaction: out of gas

Ahh… actually I see what’s going on. Turns out that simple test contract is getting more and more expensive. Does truffle test use a different default gas limit than truffle migrate? I had tuned it up to handle the migration and must have been lucky. It seems on v4.1.6 it cost 5913212 gas and now on v4.1.7 it costs 6109322 to deploy the test contract.

I no longer work at that company and don’t have an environment setup to further investigate. If I recall correctly, I used a value higher than 6.7M – but at first I was trying to keep it high enough but not super close to the block limit. Things greatly improved when I turned on compiler optimizations… Sorry I’m not super interested anymore and can’t quite help you further.
