Test::Unit::TestCase

Public Class Methods

pending(description, &block) click to toggle source

This method will define a test method using the description as the test name (“pending function” => “test_pending_function“)

Instead of doing this:

def test_function_is_pending

  pending "this test is pending"

end

You can just do this:

pending “function is pending“

This method can be called with a block passed, the same as the instance method

    # File lib/pending.rb, line 76
76:       def self.pending(description, &block)
77:         test_name = "test_#{description.gsub(/\s+/,'_')}".to_sym
78:         defined = instance_method(test_name) rescue false
79:         raise "#{test_name} is already defined in #{self}" if defined
80:         define_method(test_name) do
81:           pending(description) {self.instance_eval(&block)}
82:         end
83:       end

Public Instance Methods

pending(description = "", &block) click to toggle source

The pending method lets you define a block of test code that is currently “pending” functionality.

You can use it two ways. One is simply put a string as the parameter:

  def test_web_service_integration
    pending "This is not done yet..."
  end

This will output a “P” in the test output alerting there is pending functionality.

You can also supply a block of code:

  def test_new_helpers
    pending "New helpers for database display" do
      output = render_record(User.first)
      assert_equal "Jerry User (jerry@users.com)", output
    end
  end

If the block doesn’t fail, then the test will flunk with output like:

  <New helpers for database display> did not fail.

If the test fails (i.e., the functionality isn’t implemented), then it will not fail the surrounding test.
