假设我想要以下包结构,并且想要使用 ReTest 的并行测试(我的问题似乎是代码加载在分布式中的工作方式,因此这实际上并不是 ReTest 特定的问题)。
| root/
| MyPackage/
| Project.toml
| Manifest.toml
| src/
| MyPackage.jl
| test/
| runtests.jl
| MyPackageTests.jl
我通过以下方式初始化了这个包:
$ cd root && julia
(...) pkg> generate MyPackage;
$ cd MyPackage && julia
(...) pkg> activate .
(...) pkg> instantiate
(...) pkg> add ReTest InlineTest Distributed;
...
Fill in MyPackage.jl
, runtests.jl
, and MyPackageTests.jl
一些 Julia 代码。
该代码是什么不太重要 - 尽管我遵循在重新测试中 https://github.com/JuliaTesting/ReTest.jl/blob/master/docs/src/index.md.
然后进行设置:
$ julia
(...) pkg> activate .
(...) pkg> instantiate
(MyPackage) pkg> st

我想了解这是为什么。在 GitHub 上我看到这个问题据说已经解决了 https://github.com/JuliaLang/julia/issues/26805。当我跑步时我可以确认that例如,我也遇到与上面 MyPackage 完全相同的问题,如果using
语句涉及环境所针对的包。
在提交错误或打开问题之前,我想在这里检查一下,以防这是我的流程问题。如果没有,显然分布式/重新测试有问题,我将为这些问题开票。非常感谢任何帮助。
