MiniTest::Spec — The faster, better, less-magical spec framework!

For a list of expectations, see MiniTest::Expectations.

Methods

Constants

TYPES = [[//, MiniTest::Spec]]   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

Public Class methods

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.

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.

This is used to define a new benchmark method. You usually don‘t use this directly and is intended for those needing to write new performance curve fits (eg: you need a specific polynomial fit).

See ::bench_performance_linear for an example of how to use this.

Create a benchmark that verifies that the performance is constant.

  describe "my class" do
    bench_performance_constant "zoom_algorithm!" do
      @obj.zoom_algorithm!
    end
  end

Create a benchmark that verifies that the performance is exponential.

  describe "my class" do
    bench_performance_exponential "algorithm" do
      @obj.algorithm
    end
  end

Create a benchmark that verifies that the performance is linear.

  describe "my class" do
    bench_performance_linear "fast_algorithm", 0.9999 do
      @obj.fast_algorithm
    end
  end

Returns the children of this spec.

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.

Hint: If you do want inheritence, use minitest/unit. You can mix and match between assertions and expectations as much as you want.

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

Figure out the spec class to use based on a spec‘s description. Eg:

    spec_type("BlahController") # => MiniTest::Spec::Rails
