I am using truffle (javascript) to test my solidity contracts and want to automatically run my contract functions a large number of times. I can't figure out how to make a for loop work with promises however as I need it to wait until the whole loop is finished to start again. I'm currently just using a regular for loop with the promises chained up within it. I have included below my roughly anonymised code. Thanks for(var j = 0; j < 5; j++) { //create parameters for function runFunc(param1 ,param2); } function runFunc(param1, param2) { contract.func1.call(param1).then(function(return1) { var var1 = = web3.toAscii(account1hash.valueOf()); contract.func2(param2, var1).then(function() { contract.func3(param1, param2); }); }); }

NB: accounts is a global variable with test wallets passed in to the test by truffle. should.be.fulfilled is using the chai-as-promised NPM module - checks for errors it('Checks we are keeping track of total enlisted', async function() { for (var i=0; i < accounts.length; i++) { await this.WhitelistV2.enlist(accounts[i], {from: _}).should.be.fulfilled; total +=1; } total.should.be.equal(accounts.length); });
