Coverage provides coverage measurement feature for Ruby. This feature is experimental, so these APIs may be changed in future.
(1) require “coverage.so” (2) do ::start (3) require or load Ruby source file (4) ::result will return a hash that contains filename as key and
coverage array as value.
[foo.rb] s = 0 10.times do |x| s += x end if s == 45 p :ok else p :ng end [EOF] require "coverage.so" Coverage.start require "foo.rb" p Coverage.result #=> {"foo.rb"=>[1, 1, 10, nil, nil, 1, 1, nil, 0, nil]}
Returns a hash that contains filename as key and coverage array as value and disables coverage measurement.
static VALUE rb_coverage_result(VALUE klass) { VALUE coverages = rb_get_coverages(); VALUE ncoverages = rb_hash_new(); if (!RTEST(coverages)) { rb_raise(rb_eRuntimeError, "coverage measurement is not enabled"); } st_foreach(RHASH_TBL(coverages), coverage_result_i, ncoverages); rb_hash_freeze(ncoverages); rb_reset_coverages(); return ncoverages; }
