Metaphone

a phonetic algorithm, published by Lawrence Philips in 1990, for indexing words by their English pronunciation. It uses information about variations and inconsistencies in English spelling and pronunciation to produce a more accurate encoding, which does a better job of matching words and names which sound similar.

Why does this matter?

In real life, this algorithm can be used for voice translation as well as similar sounding names search.

Good Unit Test Qualities

  • Repeatable
    Unit tests should be repeatable. If a test fails, it should always fail, if it succeed, it should always be.
    Good unit tests also repeatable all the time, not succeed at certain time, but fail at other times.
  • Independent
    Each unit test should be independent, meaning it should not depend on other unit test for it to run.
    You should also be able to run each unit test by itself, or a select group of tests.
