Signature surveys

Jim Weirich writes on stripping out the text from a program, leaving only the "line noise" (punctuation). He notes:

What I find interesting is the amount of semantic information that still comes through the "line noise". For example, the "#<>" sequence in the C++ code is obviously an include statement for something in the standard library and the "<<" are output statements using "cout".

That reminds me of something that Ward Cunningham described. He called them "signature surveys". It's a really sweet idea, even more impressive when you see him demo it.

Working your way out of the automated GUI testing tarpit
  1. Three ways of writing the same test
  2. A test should deduce its setup path
  3. Convert the suite one failure at a time
  4. You should be able to get to any page in one step
  5. Extract fast tests about single pages
  6. Link checking without clicking on links
  7. Workflow tests remain GUI tests
