## Upgrading

The changes lend themselves to the following workflow for upgrading from the 2nd to the 3rd edition:

1. Activate edition 3. You can let [`usethis::use_testthat(3)`](https://usethis.r-lib.org/reference/use_testthat.html) do this for you.
2. Remove or replace deprecated functions, going over the list of above.
3. If your output got noisy, quiet things down by either capturing or suppressing warnings and messages.
4. Inspect test outputs if objects are not "all equal" anymore.

## Alternatives

You might wonder why we came up with the idea of an "edition", rather than creating a new package like testthat3.
