测试驱动开发的关键要点与常见错误

一、测试驱动开发基础

1. 八进制转换器示例

以下是八进制转换器的部分代码及测试：

def reduce
  @number = @number / 8
end
def finished?
  @number == 0
end
end
describe OctalConverter do
  it 'should return 1 in octal for 1 in decimal' do
    converter = OctalConverter.new(1)
    result = converter.convert
    assert_equal [1], result
  end
  it 'should return 2 in octal for 2 in decimal' do
    converter = OctalConverter.new(2)
    result = converter.convert
    assert_equal [2], result
  end
  it 'should return 10 in octal for 8 in decimal' do
    converter = OctalConverter.new(8)
    result = converter.convert
    assert_equal [1,0], result
  end
  it 'should return 137 in octal for 95 decimal' do
    converter = OctalConverter.new(9
