Why would anyone build with this?

REASON 1

Write automated tests that run a Yeoman generator and verify it creates all the expected files.

REASON 2

Simulate answering a generator's prompts programmatically instead of manually typing responses each test run.

REASON 3

Check that a generator respects different user choices and still produces valid code.

REASON 4

Add yeoman-test as a dev dependency to catch generator regressions before publishing an update.
