Also, the linked page is in Japanese.

The page illustrates how a unit test can serve as an executable specification. The third box of code is a TestFixture class with methods like this one: >> [Test][ExpectedException(typeof(ArgumentException))] >> public void 一年未満はエラーになる() >> { >> Date date = new Date(0, 1, 1); >> } The name translates to something like "if the year is less than one, it's an error". Interesting. Kind of a weird thing to do; ordinarily you wouldn't want method names that take so long to type. But a unit test method is a special case. The mix of Japanese and English is not as visually jarring as I expected. It actually looks kinda cool. :)

Thanks for the translation!

This meshes nicely with a pattern I've only recently learned in unit testing -- using long descriptive names for tests so the name of the test indicates the tested behavior (as opposed to, say, the name of the class or method being tested).
