"make tests" fails in tests/spend.py

[tumblecatweed]

Test fails here, but it's strange same function is called many times without error in this script.

request(2, "mine_block", [1,100000], 0.1)

Python version is 2.7.15

There is some non-deterministic errors in the integration tests. If you run them one at a time, it is easier to get them all to pass.

It would be nice if we could fix this.

174 I sent a PR to fix this issue. Please review.

Great job

@tumblecatweed is this good to close now? Zack is pretty busy, if this is resolved, maybe you can close it.

I was able to significantly decrease these errors by decreasing the target block time when using test mode.

If the target is too high, then tests fail because blocks fail to get mined.

if the target is too low, there is some error that happens when the blockchain is always trying to decrease the target, and the target hits zero. divide by zero or something I guess.

Thanks, I close this issue.
