Right before the section in the GS guide called "Building Forms To Create Records", there's some test output shown:
9 runs, 16 assertions, 0 failures, 0 errors, 0 skips
This test output has changed in v1.2 to:
12 runs, 20 assertions, 0 failures, 0 errors, 0 skips
I guess there have been some new tests added in the interim?
I am submitting this as an issue and not a PR because I couldn't find a 1.2-specific getting started guide at the moment.
