Description of issue

How do I run brew tests with a different brew binary?

[p-linnane]

Can you elaborate a little more? What are you trying to achieve?

[ossenthusiast]

I want to run an earlier version tests for an older version of the binary. So something like this: BREW_BIN_PATH="./my_old_binary" brew tests

[SMillerDev]

It's still not clear to me, you're trying to test an older brew version?

[ossenthusiast]

It's still not clear to me, you're trying to test an older brew version?

Yes, I am trying to test older brew version with the new tests.

[p-linnane]

This isn't really something that's supported. We are a rolling release package manager, meaning only the latest version is supported.

Fair enough, I was just curious whether something like this was possible.
