My first thought when reading this (and the recent discussion on Python ideas) was that pytest already does this.
Then I see in the PEP: "What pytest does is awesome“ So what? Well, two points: 1) this should be part of a test framework, not something built in to exceptions. Pytest has shown that it can be done without any language changes. 2) there are a lot of things in Pytest that are very useful. And a lot of problems with unittest. So maybe what we should do now, rather than add one feature, is propose a new test framework/test runner for the stdlib, inspired by pytest. Alternatively, take the approach taken with distutils and setuptools— officially accept that a full featured test framework will be left to third parties. NOTE: if the proposal does require actual language changes beyond the current introspection options, that should be made clear. -CHB On Fri, Sep 24, 2021 at 4:12 AM Paul Moore <p.f.mo...@gmail.com> wrote: > On Fri, 24 Sept 2021 at 12:05, Noam Tenne <n...@10ne.org> wrote: > > > Caveats > > ------- > > > > It is important to note that expressions with side effects are affected > by this feature.
