The t.Parallel method does not interact well with the -failfast flag. See golang/go#30522. Instead, start off tests ourselves in a goroutine. Doing it this way allows the -failfast flag to take effect sooner. One nice benefit of this change is that the test output is cleaner: Before: <<< === RUN Test === RUN Test/Go1.9.7 === RUN Test/Go1.9.7/TestNormal === PAUSE Test/Go1.9.7/TestNormal === RUN Test/Go1.9.7/TestPureGo === PAUSE Test/Go1.9.7/TestPureGo === RUN Test/Go1.9.7/TestReflect === PAUSE Test/Go1.9.7/TestReflect === CONT Test/Go1.9.7/TestNormal === CONT Test/Go1.9.7/TestReflect === CONT Test/Go1.9.7/TestPureGo === RUN Test/Go1.10.8 === RUN Test/Go1.10.8/TestNormal === PAUSE Test/Go1.10.8/TestNormal === RUN Test/Go1.10.8/TestPureGo === PAUSE Test/Go1.10.8/TestPureGo === RUN Test/Go1.10.8/TestReflect === PAUSE Test/Go1.10.8/TestReflect === CONT Test/Go1.10.8/TestNormal === CONT Test/Go1.10.8/TestReflect === CONT Test/Go1.10.8/TestPureGo === RUN Test/Go1.11.6 === RUN Test/Go1.11.6/TestNormal === PAUSE Test/Go1.11.6/TestNormal === RUN Test/Go1.11.6/TestPureGo === PAUSE Test/Go1.11.6/TestPureGo === RUN Test/Go1.11.6/TestReflect === PAUSE Test/Go1.11.6/TestReflect === CONT Test/Go1.11.6/TestNormal === CONT Test/Go1.11.6/TestReflect === CONT Test/Go1.11.6/TestPureGo === RUN Test/Go1.12.1 === RUN Test/Go1.12.1/TestNormal === PAUSE Test/Go1.12.1/TestNormal === RUN Test/Go1.12.1/TestPureGo === PAUSE Test/Go1.12.1/TestPureGo === RUN Test/Go1.12.1/TestReflect === PAUSE Test/Go1.12.1/TestReflect === RUN Test/Go1.12.1/TestProto1Legacy === PAUSE Test/Go1.12.1/TestProto1Legacy === RUN Test/Go1.12.1/TestProtocGenGo === PAUSE Test/Go1.12.1/TestProtocGenGo === RUN Test/Go1.12.1/TestProtocGenGoGRPC === PAUSE Test/Go1.12.1/TestProtocGenGoGRPC === CONT Test/Go1.12.1/TestNormal === CONT Test/Go1.12.1/TestProto1Legacy === CONT Test/Go1.12.1/TestProtocGenGoGRPC === CONT Test/Go1.12.1/TestProtocGenGo === CONT Test/Go1.12.1/TestReflect === CONT Test/Go1.12.1/TestPureGo === RUN Test/ConformanceTests === RUN Test/GeneratedGoFiles === RUN Test/FormattedGoFiles === RUN Test/CommittedGitChanges === RUN Test/TrackedGitFiles --- PASS: Test (509.59s) --- PASS: Test/Go1.9.7 (0.00s) --- PASS: Test/Go1.9.7/TestReflect (100.81s) --- PASS: Test/Go1.9.7/TestNormal (100.88s) --- PASS: Test/Go1.9.7/TestPureGo (56.93s) --- PASS: Test/Go1.10.8 (0.00s) --- PASS: Test/Go1.10.8/TestNormal (64.85s) --- PASS: Test/Go1.10.8/TestReflect (65.20s) --- PASS: Test/Go1.10.8/TestPureGo (36.14s) --- PASS: Test/Go1.11.6 (0.00s) --- PASS: Test/Go1.11.6/TestReflect (59.69s) --- PASS: Test/Go1.11.6/TestNormal (60.25s) --- PASS: Test/Go1.11.6/TestPureGo (34.17s) --- PASS: Test/Go1.12.1 (0.00s) --- PASS: Test/Go1.12.1/TestProto1Legacy (59.41s) --- PASS: Test/Go1.12.1/TestNormal (59.87s) --- PASS: Test/Go1.12.1/TestProtocGenGo (3.55s) --- PASS: Test/Go1.12.1/TestProtocGenGoGRPC (4.12s) --- PASS: Test/Go1.12.1/TestReflect (60.10s) --- PASS: Test/Go1.12.1/TestPureGo (60.66s) --- PASS: Test/ConformanceTests (0.78s) --- PASS: Test/GeneratedGoFiles (8.99s) --- PASS: Test/FormattedGoFiles (2.64s) --- PASS: Test/CommittedGitChanges (0.10s) --- PASS: Test/TrackedGitFiles (0.00s) PASS >>> After: <<< === RUN Test === RUN Test/Go1.9.7/PureGo === RUN Test/Go1.9.7/Normal === RUN Test/Go1.9.7/Reflect === RUN Test/Go1.10.8/Normal === RUN Test/Go1.10.8/PureGo === RUN Test/Go1.10.8/Reflect === RUN Test/Go1.11.6/Normal === RUN Test/Go1.11.6/PureGo === RUN Test/Go1.11.6/Reflect === RUN Test/Go1.12.1/Normal === RUN Test/Go1.12.1/PureGo === RUN Test/Go1.12.1/Reflect === RUN Test/Go1.12.1/Proto1Legacy === RUN Test/Go1.12.1/ProtocGenGo === RUN Test/Go1.12.1/ProtocGenGoGRPC === RUN Test/ConformanceTests === RUN Test/GeneratedGoFiles === RUN Test/FormattedGoFiles === RUN Test/CommittedGitChanges --- PASS: Test (182.87s) --- PASS: Test/Go1.9.7/PureGo (72.17s) --- PASS: Test/Go1.9.7/Normal (72.59s) --- PASS: Test/Go1.10.8/Normal (8.03s) --- PASS: Test/Go1.10.8/PureGo (8.03s) --- PASS: Test/Go1.10.8/Reflect (8.34s) --- PASS: Test/Go1.11.6/Normal (10.70s) --- PASS: Test/Go1.11.6/PureGo (8.21s) --- PASS: Test/Go1.11.6/Reflect (8.77s) --- PASS: Test/Go1.12.1/Normal (7.41s) --- PASS: Test/Go1.12.1/PureGo (6.52s) --- PASS: Test/Go1.12.1/Reflect (6.04s) --- PASS: Test/Go1.12.1/Proto1Legacy (6.96s) --- PASS: Test/Go1.12.1/ProtocGenGo (1.15s) --- PASS: Test/Go1.12.1/ProtocGenGoGRPC (2.43s) --- PASS: Test/Go1.9.7/Reflect (88.47s) --- PASS: Test/ConformanceTests (1.81s) --- PASS: Test/GeneratedGoFiles (16.28s) --- PASS: Test/FormattedGoFiles (3.17s) --- PASS: Test/CommittedGitChanges (0.17s) PASS >>> Change-Id: I777ffe3f4d5f6407c87e3866cbaa890017204cba Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/185877 Reviewed-by: Herbie Ong <herbie@google.com>
Next Generation Go Protocol Buffers
WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.
This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
