A Rake task that runs a set of specs.
This will create a task that can be run with:
If rake is invoked with a "SPEC=filename" command line option, then the list of spec files will be overridden to include only the filename specified on the command line. This provides an easy way to run just one spec.
If rake is invoked with a "SPEC_OPTS=options" command line option, then the given options will override the value of the spec_opts attribute.
If rake is invoked with a "RCOV_OPTS=options" command line option, then the given options will override the value of the rcov_opts attribute.
rake spec # run specs normally rake spec SPEC=just_one_file.rb # run just one spec file. rake spec SPEC_OPTS="--diff" # enable diffing rake spec RCOV_OPTS="--aggregate myfile.txt" # see rcov --help for details
Each attribute of this task may be a proc. This allows for lazy evaluation, which is sometimes handy if you want to defer the evaluation of an attribute value until the task is run (as opposed to when it is defined).
This task can also be used to run existing Test::Unit tests and get RSpec output, for example like this:
