Note: This RFP is open to everyone. Please submit a proposal if you are competent in this domain and interested in performing this work. If your proposal is accepted, your work will be paid for in DCR as the work is completed. Please send all proposals to: rfp2016 <at> decred.org Closing Date All proposals must be submitted by 6 PM UTC July 8th, 2016. Description In order to prevent regressions with RPC calls and provide quality assurance for users of dcrd and dcrwallet, behavioral test coverage is required. The test coverage will be implemented in Go using the dcrrpcclient package and make use of an RPC test harness. This is the first of several RFPs that will address the RPC test harness coverage, and the focus will be on adding coverage for the most important and most frequently-used RPC calls. Requirements Experience programming in Go Experience writing test coverage Scope Since this is the first of several RFPs that address behavioral test coverage using an RPC test harness, this RFP will not cover all ~140 RPC calls. A subset of these RPC calls has been identified as those most frequently used by Decred users, so we will begin by adding test coverage for these RPCs. There are a handful of additional RPCs that did not make this list that are extremely important for the accurate functioning of exchanges and mining pools, and these are also included. All RPC calls will be tested using positive tests, and negative tests will be expected where they make sense. An example would be that a negative test for validateaddress makes sense whereas a negative test for getstakeinfo doesn't make sense. Tests will make heavy use of the dcrrpcclient package and require comments that make clear what each test is doing. The RPC calls to be covered in this RFP are getnewaddress validateaddress walletpassphrase sendtoaddress sendfrom sendmany getbalance listaccounts listunspent listtransactions getwalletfee/settxfee get/setticketfee get/setticketmaxprice get/setbalancetomaintain purchaseticket gettickets getstakeinfo walletinfo These tests will be run in series after a single simnet chain has been generated for testing. The RPC test harness creates a fresh simnet chain that is tested after it reaches stake validation height. Example tests for sendtoaddress and sendfrom have been included to provide some guidance on what will be expected. Keep in mind that testing one RPC call typically requires performing one or more other RPC calls in the process. Please contact the Decred developers in the #decred-dev IRC channel if you have questions about what is expected in terms of test coverage. Estimated Work 2 weeks FTE or greater (1 FTE = 40 hrs/week). Proposal Proposals should include: References to prior work with Go and test coverage Estimated completion time Milestones Partial payments shall be made at the following milestones: Complete test coverage for the following RPC calls: getnewaddress, validateaddress, walletpassphrase, getbalance, listaccounts, listunspent Complete test coverage for the following RPC calls: sendtoaddress, sendfrom, sendmany, listtransactions, getalletfee/settxfee, get/setticketfee Complete test coverage for the remaining RPC calls: gettickets, purchaseticket, get/setticketmaxprice, get/setbalancetomaintain, getstakeinfo, walletinfo Modification of these proposed milestones is acceptable, and must be accompanied by sound reasoning in a proposal. Under no circumstances shall payments be made in advance of work being completed.
