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::LifecycleHooks#teardown.
# File minitest-5.14.2/lib/minitest/spec.rb, line 198 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::LifecycleHooks#setup.
# File minitest-5.14.2/lib/minitest/spec.rb, line 184 def before _type = nil, &block define_method :setup do super() self.instance_eval(&block) end 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 minitest-5.14.2/lib/minitest/spec.rb, line 216 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 minitest-5.14.2/lib/minitest/spec.rb, line 240 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) - %w[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 minitest-5.14.2/lib/minitest/spec.rb, line 139 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 minitest-5.14.2/lib/minitest/spec.rb, line 153 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
