META: Development of build-env:create-project command

[greg-1-anderson]

The build-env:create-project command is under development. Backwards compatibility is not guaranteed for future changes to this command until version 1.3.0 is tagged.

Initial requirements:

• Create a GitHub project from a template
  • example-drops-8-composer
  • example-drops-7-composer
  • WordPress
• Create a Pantheon site
• Configure Circle CI to test the GitHub project on the Pantheon site on each PR
• Has functional tests that creates GitHub/Pantheon/Circle projects and confirms that the configured Circle tests pass
• Tears down test projects once tests complete
• Has "plugable" site-install strategy when creating new sites
• Detect whether site supports multidev, and degrade to dev-only testing if it does not.

Later changes:

• Refactor commandfile implementation into multiple classes (requires Terminus 1.1.1)
• Repository providers other than GitHub
  • Bitbucket
  • Gitlab
• CI services other than Circle
  • Travis
  • Jenkins
  • Gitlab
• More testing improvements
  • Keep last set of sites for inspection after tests; tear down old test projects at beginning of next test
  • Add flags to teardown ("obliterate") command to force deletion / ignore errors
  • Add a scenario that creates a pull request on the test repository and confirms that a multidev environment is created, and that the change is tested

For discussion on permutation testing, see #5.
