# 后端测试,带增量编译:把后端源码同步到一个固定目录,在那里 dotnet build / test。
|
||
# 用法:verify-backend.sh [fast|slow]
|
||
# fast(默认):除了标了 Category=Slow 的以外的全部测试,约 20 秒,出镜像之前要过;
|
||
# slow:只跑标了 Category=Slow 的端到端测试(真实时间的阶梯、要等测量块出来,合起来一百来秒),和出镜像并行跑,失败照样红,但不拦着出镜像。
|
||
#
|
||
# 为什么:每条流水线的工作区都是新克隆的(路径、文件时间都是新的),MSBuild 没法增量,每次从零编译整个解决方案要两分钟。
|
||
# 固定目录里 obj/bin 留着,同步时只更新内容真的变了的文件(按内容比较,没变的文件时间不动),MSBuild 就只重编译受影响的项目;
|
||
# 改动小的时候整个测试 20–30 秒。
|
||
#
|
||
# 同一时间只允许一条流水线用这份缓存(flock);增量编译失败(缓存坏了)就清掉缓存从头编译一次,所以最坏也只是回到原来的速度。
