Comprehensive testing script with RSpec + Aruba

[wtsnjp]

Texdoc used to have only limited test scripts. Since I became a maintainer of the program, I have been trying to write comprehensive test scripts with RSpec + Aruba, but the work is still in progress.

Here's a rough plan of the entire specs (this will be updated accordingly):

• action
  • files: the --files action
  • help: the --help action
  • version: the --version action
  • just view: the --just-view action
• config
  • built-in: the default values
  • environment variables: does ENV work?
  • texdoc.cnf: does texdoc.cnf work?
  • texdoc-dist.cnf: is the shipped texdoc.cnf fine?
• misc
  • errors: error messages and status codes
  • getopt: the command line option (CMO) parser
  • verbose: info messages (messages output with -v option)
• mode
  • view: the view mode (-w)
  • mixed: the mixed mode (-m)
  • list: the list mode (-l)
  • showall: the showall mode (-s)
• score
  • adjscore: the adjscore directive
  • heuristic: the heuristic pattern score, bonus score
  • order: docfile order
• search
  • fuzzy: fuzzy search
  • aliases: the aliases in texdoc.cnf
  • texdocs: documents in TEXDOCS
  • database: documents in databases
• unit
  • texdoclib: check for overall behavior
  • alias: unit tests for texdoclib-alias.tlu
  • score: unit tests for texdoclib-score.tlu
  • search: unit tests for texdoclib-search.tlu
  • util: unit tests for texdoclib-util.tlu
• view
  • file detection: for each extension
  • command: the view commands
