Overview

This class can be used as a replacement for Rake::TestTask. It is a subclass of Rake::TestTask and maintains additional information for running RubyBreaker as a Rake test task.

For example, the following shows how to run RubyBreaker in a test task:

desc “Run testtask test” Rake::RubyBreakerTestTask.new(:“testtask_test”) do |t|

t.libs << "lib"
t.test_files = ["test/testtask/tc_testtask.rb"]
t.break = ["SampleClassA"]

end

Constructor Details

#initialize(taskname = "", *args, &blk) ⇒ RubyBreakerTestTask

This overrides the testtask’s constructor. In addition to the original behavior, it keeps track of RubyBreaker options and store them in a yaml file.
