Feature: Run and save commands
  In order to organize and run commonly-used commands
  I want to save commands in an organized fashion
    And to be able to invoke any saved command easily
  So I don't have the hassle of creating a bunch of unorganized aliases
 
  Scenario: Basic UI
    When I get help for "fav"
    Then the exit status should be 0
      And the banner should be present
      And there should be a one line summary of what the app does
      And the banner should include the version
      And the banner should document that this app takes options
      And the banner should document that this app's arguments are:
        |command_name|which is required|

  Scenario: Add a Command
    When I run `fav -a 'man cp' mc`
    Then the ungrouped command "man cp" is added with name "mc"

  Scenario: Add a Command to a Group
    When I run `fav -a 'ls -l' -g TestGroup gr`
    Then the command "ls -l" is added with name "gr" to the group "TestGroup"

  Scenario: Remove an Ungrouped Command
    Given a file named "/tmp/home/.favs" with:
      """
      ef = "echo Foo"
      eb = "echo Bar"
      """
    When I run `fav -r ef`
    Then the command with name "ef" no longer exists as a fav
      And the ungrouped command "echo Bar" is added with name "eb"

  Scenario: Remove a Grouped Command
    Given a file named "/tmp/home/.favs" with:
      """
      [test]
      ef = "echo Foo"
      eb = "echo Bar"
      """
    When I run `fav -g test -r ef`
    Then the command with name "ef" no longer exists as a fav in the group "test"
      And the command "echo Bar" is added with name "eb" to the group "test"

  Scenario: Run a Command
    Given a file named "/tmp/home/.favs" with:
      """
      cpt = "touch /tmp/home/test.txt"
      """
    When I run `fav cpt`
    Then the file "test.txt" exists in "/tmp/home"

  Scenario: Run a Grouped Command
    Given a file named "/tmp/home/.favs" with:
      """
      [test]
      cpt = "touch /tmp/home/test2.txt"
      """
    When I run `fav -g test cpt`
    Then the file "test2.txt" exists in "/tmp/home"

  Scenario: Run an entire group of commands
    Given a file named "/tmp/home/.favs" with:
      """
      [test]
      cpt2 = "touch /tmp/home/test2.txt"
      cpt = "touch /tmp/home/test.txt"
      """
    When I run `fav -g test --no_prompt`
    Then the file "test2.txt" exists in "/tmp/home"
      And the file "test.txt" exists in "/tmp/home"

  Scenario: Run a command that prepends text to the end
    Given a file named "/tmp/home/.favs" with:
      """
      e = "echo $0"
      """
    When I run `fav e 'foo'`
    Then it should pass with:
      """
      foo
      """

  Scenario: Add a Command without a Command Name
    When I run `fav -a 'echo I am a command'`
      Then it should fail with:
      """
      Must specify command name when adding a fav.
      """

  Scenario: Remove a Command without a Command Name
    When I run `fav -r`
      Then it should fail with:
      """
      Must specify command name when removing a fav.
      """

  Scenario: Run a command for a group that doesn't exist
    When I run `fav -g NotAGroup cmd`
      Then it should fail with:
      """
      Specified group does not exist.
      """

  Scenario: List commands within a group
    Given a file named "/tmp/home/.favs" with:
      """
      ug = "echo ungrouped"
      [test]
      ef = "echo Foo"
      eb = "echo Bar"
      """
    When I run `fav -l -g test`
    Then it should pass with exactly:
      """
      ef = "echo Foo"
      eb = "echo Bar"

      """

  Scenario: List all commands
    Given a file named "/tmp/home/.favs" with:
      """
      ug = "echo ungrouped"
      [test]
      ef = "echo Foo"
      eb = "echo Bar"
      """
    When I run `fav -l`
    Then it should pass with exactly:
      """
      ug = "echo ungrouped"
      [test]
      ef = "echo Foo"
      eb = "echo Bar"

      """
