Mocha tests hang after completion when working with web3 smart contracts











up vote

favorite












I wrote some integration tests for a node app that works with Ethereum smart contracts (and thus use the contracts' state as a data storage). I am instantiating some smart contracts interfaces using web3 and in the assertion parts of the tests I am using them to check that valid information has been written to the blockchain.



However after the tests pass the mocha process is still running and I have to shut it down manually. I suspect this happens because the smart contract interfaces are basically open connections and they are not closed, I know it happens when you do the same with normal database connections (see here: Mocha hangs after execution when connecting with Mongoose).



I didn't find any disconnect or similar web3 api methods though, anyone had any similar experience with this?

          Someone pointed me that there is an --exit flag that you can pass to mocha and it kills the process after all tests have finished running, probably a good enough solution for now.

If add(), then add the data into add of service file.And the data will be added to the contacts.json file . And if display(), then display the display() of service file. And the display will take the data from contacts.json file. However, i know my code is flawed. Please correct it .
