MiniTest::Unit::TestCase
MiniTest::Spec – The faster, better, less-magical spec framework!
For a list of expectations, see MiniTest::Expectations.
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::Unit::TestCase#teardown.
# File minitest/spec.rb, line 178 def self.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::Unit::TestCase#setup.
# File minitest/spec.rb, line 164 def self.before type = nil, &block define_method :setup do super() self.instance_eval(&block) end end
Returns the children of this spec.
# File minitest/spec.rb, line 147 def self.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 inheritence, 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 inheritence, use minitest/unit. You can mix and match between assertions and expectations as much as you want.
# File minitest/spec.rb, line 196 def self.it desc = "anonymous", &block block ||= proc { skip "(no tests defined)" } @specs ||= 0 @specs += 1 name = "test_%04d_%s" % [ @specs, desc ] define_method name, &block self.children.each do |mod| mod.send :undef_method, name if mod.public_method_defined? 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/spec.rb, line 218 def self.let name, &block 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/spec.rb, line 115 def self.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/spec.rb, line 129 def self.spec_type desc TYPES.find { |matcher, klass| if matcher.respond_to? :call then matcher.call desc else matcher === desc.to_s end }.last end
