Coverband 4.2.0

NOTE: This release introduces load time and runtime Coverage. To get the full benefit of this feature you need to reset you coverage data (rake coverband:clear or clear via the web UI). Until you clear the combined result is still correct, but your runtime data will be mixed with previous data. This is due to an additive change in how we store coverage. We didn't reset by default as the coverage history for some folks may be more important than runtime breakdown.

  • loadtime vs runtime coverage
    • This fixes the coverage last seen date to exclude just load time data
    • now you can see boot time coverage vs code hit during production execution
    • list view shows runtime percentage and runtime hits
    • file view shows line hits load, runtime, and combined
  • perf speedup on gem details views
  • ajax load code views for more responsive pages on large projects
  • fix for issues with COVERBAND_DISABLE_AUTO_START
  • silence warnings
  • move from thread based reporter instance to process based instance
  • thanks Karl Baum for much of the above mentioned work
  • clear coverage on individual files
  • we have a logo, thanks Dave Woodall, http://davewoodall.com

  • improved documentation
  • supports SimpleCov.root

  • improved benchmarks including support for multiple stores ;)
