在运行完所有测试之后，是否可以执行拆解功能? [英] Is there a way to execute a teardown function after all tests have been run?

问题描述

在Rust中，使用标准测试库在所有测试(即cargo test的末尾)运行后，是否可以执行拆解功能?

In Rust, is there any way to execute a teardown function after all tests have been run (i.e. at the end of cargo test) using the standard testing library?

我不想在每个测试后运行拆卸功能，因为这些相关文章对此进行了讨论:

I'm not looking to run a teardown function after each test, as they've been discussed in these related posts:

• 如何先运行设置代码测试在Rust中运行?
• 如何初始化记录器以进行集成测试? ))

• How to run setup code before any tests run in Rust?
• How to initialize the logger for integration tests?))

这些讨论了运行的想法:

These discuss ideas to run:

• 在每个测试之前进行设置
每项测试之前的拆解(使用 std::panic::catch_unwind ) 在所有测试之前进行
• 设置(使用 std::sync::Once )

• setup before each test
• teardown before each test (using std::panic::catch_unwind)
• setup before all tests (using std::sync::Once)

一种解决方法是将cargo test调用包装起来的shell脚本，但是我仍然很好奇上述方法是否可行.

One workaround is a shell script that wraps around the cargo test call, but I'm still curious if the above is possible.

推荐答案

我不确定是否可以通过Rust的内置测试功能.第三方测试系统(例如，发光的或不锈的)可能具有该选项，可能值得研究其确切功能

I'm not sure there's a way to have a global ("session") teardown with Rust's built-in testing features, previous inquiries seem to have yielded little, aside from "maybe a build script". Third-party testing systems (e.g. shiny or stainless) might have that option though, might be worth looking into their exact capabilities

或者，如果每晚比较适合正在实施自定义测试框架功能，您可以使用这个目的.

Alternatively, if nightly is suitable there's a custom test frameworks feature being implemented, which you might be able to use for that purpose.

此外，您可能希望查看macro_rules!来清理一些样板，这是burntsushi之类的人所做的

That aside, you may want to look at macro_rules! to cleanup some boilerplate, that's what folks like burntsushi do e.g. in the regex package.
