Support *.ts files for node --test

[ThePlenkov]

What is the problem this feature will solve?

I would like to use tests using typescript, not js. Currently if I run node --test it finds nothing.

What is the feature you are proposing to solve the problem?

node --test would pick up also typescript files and execute them since typescript now is experimentally supported

What alternatives have you considered?

Of course tools like jest or vitest can do this out-of-the-box but I would really love to write native tests to have zero dependency on thridparty libraries, just pure node.

This is already supported via node --experimental-strip-types --test test.ts

@RedYetiDev correct, but it doesn't pick up *.test.ts files in the same way as it does for .js, cjs, mjs. as it is described here:

Can we --experimental-strip-types as a flag to add also ts, cts, mts files? Thanks!

[RedYetiDev]

Oh okay, that should a simple few-line fix.

I'll fix this later today if no one does so before me
