Unit test approach for Ruby extension

yue_nicholas

8/10/2006 5:44:00 AM

Hi,

I am writing a Ruby extension in C++.

Do we write unit test separately for the C++ code and the Ruby code?

I am familar with cppunit and recently with Ruby's build in unit
testing facility.

Could someone advice?

Thanks in advance.

Cheers

I would test it from ruby because it is easier to write ruby code
than C++ code.

Concur.

We even went that route for a stand-alone C code. We briefly
looked at using swig to do the interface, but ended up writing
the interface code by hand.

As the prices rise, the readership drops...economics 101.

Considering what's on Internet, who needs an "e-book?"

If you're unhappy with a situation, work to change it. It helps if you can
avoid breaking any laws. 'Twas ever thus.

Don't buy any, then. There are free e-books available. Calibre

Someone who wants to have copies of "Tom Sawyer", "Huckleberry Finn", "Great
Expectations" and "A Tale Of Two Cities" conveniently available in a small
package. A Kindle or Nook costs about $200.00, half the price of an iPad.

I think that you can get a wifi Kindle for about $79.

IIRC our wifi/3G Kindle cost $119.95 at Staples about a year ago.

I have several classics on my Kindle. Those, as you point out, are
free.

I have also bought a few books, but I ask you, why would I pay
$12.99 for an e-book when I can get the paperback for $7.95, or go to
the library, and borrow it for free.

Paperbacks tend to be fragile, get dog-eared and wear out. That happened to
my copy of "Lord of the Rings". Library books must be returned.

Different strokes...but I don't recall reading a book twice, but I
have watched several movies twice.

For a movie, "the thrill is gone" type of feeling when watching it
twice, years later.
