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