RubySpec is a project to write a complete, executable specification for the Ruby programming language. The specs describe Ruby language syntax as well as the core and standard library classes.
The RubySpec specification files are written using RSpec-compatible syntax. RubySpec provides a purpose-built framework, named MSpec, for running the specs.
The easiest way to run the RubySpecs suite is to install the MSpec gem.
$ [sudo] gem install mspec
However, RubySpec often utilizes the latest MSpec features, so you may want to use MSpec directly from the Git repository.
$ cd /somewhere $ git clone git://github.com/rubyspec/mspec.git
MSpec is now available in
To make the MSpec scripts available, add the MSpec
bin directory to you
$ export PATH=/somewhere/mspec/bin:$PATH
Once you have MSpec installed, clone the RubySpec Git repository to run the specs.
$ cd /somewhere $ git clone git://github.com/rubyspec/rubyspec.git
To run the RubySpec suite:
$ cd /somewhere/rubyspec $ mspec
This will execute all the RubySpec specs using the executable named
your current PATH.
-t option to specify the Ruby implementation with which to run the
specs. The argument may be a full path to the Ruby binary. For example, to run
$ mspec -t /opt/ruby-enterprise/bin/ruby
There are some arguments that are abbreviations for known Ruby implementations.
For example, if you specify
j, then MSpec will look for
jruby in PATH and
run RubySpec against that:
$ mspec -t j
mspec --help for a list of
To run a single spec file, pass the filename to
$ mspec core/kernel/kind_of_spec.rb
You can also pass a directory, in which case all specs in that directories will be run:
$ mspec core/kernel
Note however that passing a directory to MSpec may not always be a good idea,
because some specs aren't supposed to be run against the active Ruby
interpreter. For example, if you run
mspec -t /usr/bin/ruby1.8 library, then
MSpec will run the 1.9-specific library specs as well, even though you
specified Ruby 1.8 as the Ruby interpreter. Instead, you can specify
pseudo-directories, which are defined in ruby.1.8.mspec and ruby.1.9.mspec.
These pseudo-directories only include files appropriate for the active Ruby
