What i did first was watching at Dapp university tutorials, I manage to watch all 14 videos and run it with Ganache. But since everything is doing good at local, I created my own private network. Then.. this happens.

When I run truffle test --reset --network development

enter image description here

I think the error is happening in this area DappToken.js @ 116: enter image description here

this is my network by the way truffle.js: enter image description here

  • Are you testing with geth? Because I don't think .then(assert.fail).catch( will do what you think it does with geth.

I think your problem is on line 88, where the comment above states the test should approve the transfer of 10 tokens, you actually approve 15. This accounts for the test discrepancy of actual: 5 vs expected: 0 in your error.

  • i want to increase it from 10 to 30 in order to remove some errors... I eliminated 4 errors out of 5. Now this is the only one.

  • You see, you're doing some math, and the last test (on line 116 in your code above) is testing that the final result is 0. If you add 20 to the starting value, you'll need to increase that final check accordingly.
