Please describe your feature

Currently we have buildtest build --stage=build which really doesn't make sense we should make this be buildtest build --dry-run where its sole purpose is to show list of tests that will potentially be run without actually running them.

That being said we should remove option buildtest build --stage=build

Suggest potential solution

Additional Information

• Add cli option --dry-run in argparser
• Add option to bash completion
• Remove option --stage from argparser and remove implementation see

  buildtest/buildtest/cli/build.py

  if self.stage == "build":

• Update json schema https://github.com/buildtesters/buildtest/blob/devel/buildtest/schemas/settings.schema.json for adding property dryrun in the profiles section which will be used to record option into configuration file when buildtest build --dryrun --save-profile is specified
• Update methods

  Line 853 in c783521

  def save_profile_to_configuration(self):

  and and

  buildtest/buildtest/cli/build.py

  def load_profile(self):

  to record dryrun as an option that is saved into rerun file and loaded back up when buildtest build --profile is used
• Update docs page https://github.com/buildtesters/buildtest/blob/devel/docs/gettingstarted/buildingtest.rst by removing reference to --stage. Best would be to use search feature in the docs to find all reference to --stage and remove it.
• Add doc section for dry-run same page (https://github.com/buildtesters/buildtest/blob/devel/docs/gettingstarted/buildingtest.rst)
• Add regression test in class TestBuildTest in https://github.com/buildtesters/buildtest/blob/devel/tests/cli/test_build.py
• Please add argument dryrun when calling BuildTest class in

  buildtest/tests/cli/test_build.py
