Ability to check if running inside tests?

[nickrobinson251]

Feature request:

are there env. vars or checks that can be done in the source code to detect if it's inside a test case?

For comparison

• PyTest has a PYTEST_VERSION env var (Add a function to detect if pytest is running pytest-dev/pytest#9502 / pytest-dev/pytest@48b6d18)
• Go has testing.Testing() (testing: add func Testing() bool golang/go#52600 / golang/go@7f38067)
• would be worth looking into other frameworks too (Jest, Rspec, Cargo, etc)

Are you saying ReTestItems should set something to users can know? Or asking if Julia itself provides (or should provide) something?

There is Test.get_testset() which relies on a scoped value to set the value of the current testset that is "in scope".

I was wondering if @testitem should set a ScopedValue, but hadn't considered that Test might do that already!

[nickrobinson251]

I think you're right, using Test.get_testset() (or Test.get_testset_depth()) to know if you’re inside a @testset (or a @testitem which doubles up as a @testset) is the way to do this.

Although it's not until Julia v1.13+ that this is a ScopedValue and so will work right with tests that spawn tasks

Thanks, Jacob!
