Method: Object#language_version

Defined in:
lib/extensions/mspec/mspec/helpers/language_version.rb

#language_version(dir, name) ⇒ Object

Helper for syntax-sensitive specs. The specs should be placed in a file in the versions subdirectory. For example, suppose language/method_spec.rb contains specs whose syntax depends on the Ruby version. In the language/method_spec.rb use the helper as follows:

language_version __FILE__, "method"

Then add a file “language/versions/method_1.8.rb” for the specs that are syntax-compatible with Ruby 1.8.x.

The most version-specific file will be loaded. If the version is 1.8.6, “method_1.8.6.rb” will be loaded if it exists, otherwise “method_1.8.rb” will be loaded if it exists.
