How do I manage unlocking accounts in a test in Truffle

Question

I have a test that exercises a contract function across different accounts. How do I unlock these accounts in the context of the test?

contract('MyContract', function (accounts) {

    it("should perform differently for different accounts", function (done) {

        var thisContract = MyContract.deployed();

        thisContract.addAccounts([accounts[1], accounts[2]], {from: accounts[0]} ).then(
            function (tx_id) {
              /* this works because I manual unlock acc 0 on geth */
                return thisContract.doSomething({from: accounts[0]});
            }).then(
            function (tx_id) {
              /* is there something here I can do to unlock acc 1? */
                return thisContract.doSomething({from: accounts[1]});
            }).then(
            function (tx_id) {
              /* then here... */
                return thisContract.doSomething({from: accounts[2]};
                done();
            }
        ).catch(done);

    });

});

Answer 1

You cannot unlock accounts from your code. It would be an issue if a code can unlock your accounts.

It seems like you are writing unit tests. Instead of running geth, you might want to try using testrpc. Accounts in testrpc do not need to be unlocked before use.
