The document discusses Cucumber, a behavior-driven development (BDD) framework that helps with test-driven development (TDD). It outlines some key features of Cucumber, including that it encourages BDD and TDD practices, supports multiple test drivers and languages, and produces readable test results. It also notes some potential downsides, such as that regex step definitions can be hard to find and the natural language parsing can be slower.

25. Natural Language @search Feature: Searching For Hello World, and some more overview of the feature that we are trying to test @google Scenario: User Searches for Hello World on Google.com Given I'm on Google's Home Page And I search for Hello World Then I should see Wikipedia's Hello World article as 1st result @bing Scenario: User Searches for Hello World on Bing.com Given I'm on Bing's Home Page And I search for Hello World Then I should see car videos as first result

26. Step Definitions Given /^I'm on Google's Home Page$/ do @selenium.open " www.google.com " end Given /^I'm on Bing's Home Page$/ do @selenium.open " www.bing.com " end When /^I search for Hello World$/ do @selenium.type "q", "Hello World" end Then /^I should see Wikipedia's Hello World article as 1st result$/ do assert_stuff end Then /^I should see car videos as first result$/ do assert_stuff end

66. @dhh RSpec offends me aesthetically with no discernible benefit for its added complexity over test/unit. Cucumber makes no sense to me unless you have clients reading the tests. Why would you build a test-specific parser for English?

Why would you build a test-specific parser for English? The important thing is of course that we get people testing, so tools shouldn't matter too much....
