Literate Testing

• Kizoom perform comprehensive testing.
• Functional tests test the application from the
  users perspective.
• Testing web pages can result in large tests.
• Robert Chatley, Tom White and I worked on a more
  literate style.
• Submitted a paper on the new style to the Int.
  Conference on Software Engineering.

Literate Testing

• Assert that the current page has three links
  named yesterday, today and tomorrow.

With thanks to Robert Chatley for this example.

• assertThat(theCurrentPage, has(exactly(3),
  links().named(yesterday, today, tomorrow)))

Now an open source project at https//lift.dev.jav
