[temp] Pages 144-6: Test::Unit Framework - Assertions == Expected results (part I)

Value: Low

Level: Easy

Summary:
The Test::Unit framework gives you: a way of expressing individual tests, a framework for structuring the tests, flexible ways of invoking the tests. Rather than have you write series of individual if statements in your tests, Test::Unit provides a series of assertions that achieve the same thing. Although a number of different styles of assertion exist, they all follow basically the same pattern. Each assertion
gives you a way of specifying a desired result or outcome and a way of passing in the
actual outcome. If the actual doesn't equal the expected, the assertion outputs a nice
message and records the fact as a failure.

Memo:

Example:

require 'roman'
require 'test/unit'
class TestRoman < Test::Unit::TestCase
def test_simple
assert_equal("i", Roman.new(1).to_s)
assert_equal("ix", Roman.new(9).to_s)
end
end
