Have an option for opting out of the version checker messages?

🚀 Feature Proposal

Hi folks, it might not be a shock but I am always using nightly TypeScript and would love to be able to opt out of the messages that it could be unstable with Jest. I dig the point of the messaging.

Happy to make the PR, but wanted to see if folks would want it be done and/or how. env vars? config?

hey @orta glad to have you here. I had some thoughts about this a while ago. I have 2 similar ideas about this:

Using env var

• This env var can be persisted after 1st run so the next run won't show the message again.

• Maybe this env var value will be updated once user uses a new TypeScript version so the message will show again and then the run after that won't show ?

Using config

The only doubt I have with this approach is: imo having too many config options are not so nice.

I'd prefer more the approach using env var. Let me know what you think :)

Simplest option might be to detect process.env.TS_JEST_IGNORE_VERSION_WARNINGS and skip the warnings, no need to anything too complex - it can cover all the different checks then?

👍LGTM, PR is welcome !

I forgot that jest creates a sandbox environment to run test, so process.env won't work. I think the only way is create a new config option.

But if user explicitly sets sys env before running tests, it should be possible to check to hide/show warning message.

hah, now I feel guilty! Thanks @ahnpnl
