Which of the following is NOT a standard Yeoman lifecycle phase?

• A. prompting
• B. testing
• C. install
• D. end

Answer: (B)

Yeoman runs through a fixed set of lifecycle phases that map to specific method names on a generator, guiding when certain tasks happen during scaffolding. These built-in phases include initializing, prompting, configuring, writing, install, and end. Among the options, prompting, install, and end are real phases you’ll see in a generator’s flow. The one that isn’t a standard phase is testing. If you define a method named testing, Yeoman won’t treat it as a recognized lifecycle stage; it would either run as a normal method you call yourself or you’d trigger tests via an external script (like npm test) rather than as part of the Yeoman lifecycle.
