/* Coverage provides coverage measurement feature for Ruby.
|
|
* This feature is experimental, so these APIs may be changed in future.
|
|
*
|
|
* = Usage
|
|
*
|
|
* (1) require "coverage.so"
|
|
* (2) do Coverage.start
|
|
* (3) require or load Ruby source file
|
|
* (4) Coverage.result will return a hash that contains filename as key and
|
|
* coverage array as value.
|
|
*
|
|
* = Example
|
|
*
|
|
* [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]}
