Where did you get this link from?

Google's #1 ranked search result for my query "Go before each test" is https://stackoverflow.com/questions/23729790/how-can-i-do-test-setup-using-the-testing-package-in-go.

The top answer has a comment under it that says, "TestMain is once in a package, so it's not that useful. I find subtests are better for more complex purposes." The word subtests is a link to https://blog-test.golang.org/subtests.

Yes, thanks you!

Thanks for clarifying.

blog-test.golang.org is not a valid subdomain at this time, and all unknown subdomains get redirected to golang.org. This is working as intended.

I'll close this since there's nothing to do on our side. If possible, the link on Stack Overflow should be edited.
