Oh look! A Minitest::Spec::DSL module! Eat your heart out DHH.
Contains pairs of matchers and Spec classes to be used to calculate the superclass of a top-level describe. This allows for automatically customizable spec types.
See: register_spec_type and spec_type
Define an ‘after’ action. Inherits the way normal methods should.
NOTE: type is ignored and is only there to make porting easier.
Equivalent to Minitest::Test#teardown.
# File lib/minitest/spec.rb, line 183 def after type = nil, &block define_method :teardown do self.instance_eval(&block) super() end end
Define a ‘before’ action. Inherits the way normal methods should.
NOTE: type is ignored and is only there to make porting easier.
Equivalent to Minitest::Test#setup.
# File lib/minitest/spec.rb, line 169 def before type = nil, &block define_method :setup do super() self.instance_eval(&block) end end
Returns the children of this spec.
# File lib/minitest/spec.rb, line 152 def children @children ||= [] end
Define an expectation with name desc. Name gets morphed to a proper test method name. For some freakish reason, people who write specs don’t like class inheritance, so this goes way out of its way to make sure that expectations aren’t inherited.
This is also aliased to specify and doesn’t require a desc arg.
Hint: If you do want inheritance, use minitest/test. You can mix and match between assertions and expectations as much as you want.
# File lib/minitest/spec.rb, line 201 def it desc = "anonymous", &block block ||= proc { skip "(no tests defined)" } @specs ||= 0 @specs += 1 name = "test_%04d_%s" % [ @specs, desc ] undef_klasses = self.children.reject { |c| c.public_method_defined? name } define_method name, &block undef_klasses.each do |undef_klass| undef_klass.send :undef_method, name end name end
Essentially, define an accessor for name with block.
Why use let instead of def? I honestly don’t know.
# File lib/minitest/spec.rb, line 225 def let name, &block name = name.to_s pre, post = "let '#{name}' cannot ", ". Please use another name." methods = Minitest::Spec.instance_methods.map(&:to_s) - ]subject] raise ArgumentError, "#{pre}begin with 'test'#{post}" if name =~ /\Atest/ raise ArgumentError, "#{pre}override a method in Minitest::Spec#{post}" if methods.include? name define_method name do @_memoized ||= {} @_memoized.fetch(name) { |k| @_memoized[k] = instance_eval(&block) } end end
Register a new type of spec that matches the spec’s description. This method can take either a Regexp and a spec class or a spec class and a block that takes the description and returns true if it matches.
Eg:
register_spec_type(/Controller$/, Minitest::Spec::Rails)
or:
register_spec_type(Minitest::Spec::RailsModel) do |desc| desc.superclass == ActiveRecord::Base end
# File lib/minitest/spec.rb, line 121 def register_spec_type(*args, &block) if block then matcher, klass = block, args.first else matcher, klass = *args end TYPES.unshift [matcher, klass] end
Figure out the spec class to use based on a spec’s description. Eg:
spec_type("BlahController") # => Minitest::Spec::Rails
# File lib/minitest/spec.rb, line 135 def spec_type desc, *additional TYPES.find { |matcher, klass| if matcher.respond_to? :call then matcher.call desc, *additional else matcher === desc.to_s end }.last end
