Feature: A shortened Git commit hash can be provided as an argument to indicate where to start taking the range of commits from till HEAD, instead of a full Git commit hash.


  Scenario Outline: A shortened and full Git commit hash can be used interchangeably.
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_commit_hash>".
    Then the linting passes.
    Given the arguments are reset.
    When the argument --from-commit-hash is provided as "<shortened_from_commit_hash>".
    Then the linting passes.


    Examples:
      | repository                                    | checkout_commit                          | from_commit_hash                         | shortened_from_commit_hash |

  Scenario Outline: The shortened Git commit hash has no matches, so an error is returned.
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_shortened_commit_hash>".
    Then their is a could not find shortened commit hash "<from_shortened_commit_hash>" error.


    Examples:
      | repository                              | checkout_commit                          | from_shortened_commit_hash |

  Scenario Outline: The shortened Git commit hash is ambiguous as multiple commit hashes match it, so an error is returned.
    Given the repository "<repository>" is cloned and checked out at the commit "<checkout_commit>".
    When the argument --from-commit-hash is provided as "<from_shortened_commit_hash>".
    Then their is a ambiguous shortened commit hash "<from_shortened_commit_hash>" error.


    Examples:
      | repository                         | checkout_commit                          | from_shortened_commit_hash |
