Feature: Plugin install command
  In order to use this plugin
  As a user of Busser
  I want to run the postinstall for this plugin

  Background:
    Given a test BUSSER_ROOT directory named "busser-shpec-install"

  Scenario: Running the postinstall generator
    When I run `busser plugin install busser-shpec --force-postinstall`
    Then the vendor directory named "shpec" should exist
    And the vendor file "shpec/bin/shpec" should contain "VERSION="
    And the output should contain "install bin/shpec"
    And the exit status should be 0
