The changes to use the builder looks good, but the change to the tests are unrelated and make me uncertain about possible regressions.

If you want to proceed with the proposed test changes I'd move them to a different PR so we can be sure the current tests all pass with the changes this PR is introducing.

Moved test changes into #882 so it could be discussed and closed or merged independently to this change
