任务说明:

这个任务是基于分支refactor/vote-contract-tests,所以有兴趣的人投票合同的重构测试用例需要从签他支dev到refactor/vote-contract-tests。(或者根据此分支在您自己的仓库上创建一个新分支。)

检查项目test/AElf.Contracts.AEDPoSExtension.Demo.Tests基本知道如何使用TestKit AEDPoS扩展。 测试用例DemoTest(如下图所示)显示了区块链系统的工作原理:选择一些事务然后将它们打包到一个块,每个新块都基于前一个块。 通过使用XXStub,您可以像调用/发送事务的特定用户一样调用测试用例中的特定合同方法。此外,您可以XXStub用于生成交易。

        [Fact]
        public async Task DemoTest()
        {
            // Check round information after initialization.
            {
                var round = await ConsensusStub.GetCurrentRoundInformation.CallAsync(new Empty());
                round.RoundNumber.ShouldBe(1);
                round.TermNumber.ShouldBe(1);
                round.RealTimeMinersInformation.Count.ShouldBe(AEDPoSExtensionConstants.InitialKeyPairCount);
            }

            // We can use this method process testing.
            // Basically this will produce one block with no transaction.
            await BlockMiningService.MineBlockAsync();
            
            // And this will produce one block with one transaction.
            // This transaction will call Create method of Token Contract.
            await BlockMiningService.MineBlockAsync(new List<Transaction>
            {
                TokenStub.Create.GetTransaction(new CreateInput
                {
                    Symbol = "ELF",
                    Decimals = 8,
                    TokenName = "Test",
                    Issuer = Address.FromPublicKey(SampleECKeyPairs.KeyPairs[0].PublicKey),
                    IsBurnable = true,
                    TotalSupply = 1_000_000_000_00000000
                })
            });
            
            // Check whether previous Create transaction successfully executed.
            {
                var tokenInfo = await TokenStub.GetTokenInfo.CallAsync(new GetTokenInfoInput {Symbol = "ELF"});
                tokenInfo.Symbol.ShouldBe("ELF");
            }

            // Next steps will check whether the AEDPoS process is correct.
            // Now 2 miners produced block during first round, so there should be 2 miners‘ OutValue isn‘t null.
            {
                var round = await ConsensusStub.GetCurrentRoundInformation.CallAsync(new Empty());
                round.RealTimeMinersInformation.Values.Count(m => m.OutValue != null).ShouldBe(2);
            }

            await BlockMiningService.MineBlockAsync(new List<Transaction>());

            {
                var round = await ConsensusStub.GetCurrentRoundInformation.CallAsync(new Empty());
                round.RealTimeMinersInformation.Values.Count(m => m.OutValue != null).ShouldBe(3);
            }

            // Currently we have 5 miners, and before this line, 3 miners already produced blocks.
            // 3 more blocks will end current round.
            for (var i = 0; i < 3; i++)
            {
                await BlockMiningService.MineBlockAsync(new List<Transaction>());
            }

            // Check round number.
            {
                var round = await ConsensusStub.GetCurrentRoundInformation.CallAsync(new Empty());
                round.RoundNumber.ShouldBe(2);
            }
            
            // 6 more blocks will end second round.
            for (var i = 0; i < 6; i++)
            {
                await BlockMiningService.MineBlockAsync(new List<Transaction>());
            }
            
            // Check round number.
            {
                var round = await ConsensusStub.GetCurrentRoundInformation.CallAsync(new Empty());
                round.RoundNumber.ShouldBe(3);
            }
        }

 

知道这一点后,您可以去test/AElf.Contracts.Vote.AEDPoSExtension.Tests尝试重构投票合同的测试用例。对于测试逻辑,只需复制当前测试用例的逻辑即可AElf.Contracts.Vote.Tests

此外,欢迎重构其他系统合同(位于其中contract/)。READMEin test/AElf.Contracts.AEDPoSExtension.Demo.Tests解释了如何创建测试项目。
