Goals

• JavaScript-ability
• improved error reporting (more finegrained, helpful, etc.)

• provide reliable perf measurements (track regressions, etc.)

rnewman desires

• embed in JS tests? (embedded HTTP server?)
• support fuzz consistency tests
• more operations (restore from bookmarks to test wipe, for example)

• Python
  • ...

• Harness
  • [DONE] clone tps repo from crossweave repo
  • refactor tests to JSON format
  • support JavaScript tests
  • refactor verify/verify-not/sync/... to be function calls
