Finite-State Machines for Web Testing

• Each web-based application or function comprises
  of different elements and phases visible to the
  web users.
• Consequently, state transition based finite-state
  machines models are proper for this type of
  applications.

Finite-State Machines for Web Testing
There are some basic components of finite-state
machines
Every web page corresponds to a slate in
finite-state machines. Any page can be the
initial state and any page can be the final state.
The input and output associated with navigations
are rather simple and straight forward the input
is the clicking of the embedded link demonstrated
as highlighted content and the corresponding
output is the loading of the requested page or
content with accompanying messages indicating the
HTML status, error or other messages.
State transitions correspond to web navigations
following hypertext links embedded in HTML
documents and other web contents. One special
case is that a user may choose to follow a
previous saved link or to directly type a URL.

• Link checking can be considered as part of
  finite-state machines based testing for
  transition coverage, but not based on formal
  models. The general finite-state machines can
  guide the general testing of the web navigations.

• Actually, web robots used by various Internet
  search engines or index services generally
  crawl the web by systematically following the
  embedded hypertext links to create indexes or
  databases of the general web contents.

• There is one evident obstacle to web
  testing using such finite-state machines the
  quantity of web pages for even a moderate-sized
  web site can be thousands or much more.
  Therefore, there would be great numbers of states
  in finite-state machines, which makes any
  detailed testing beyond simple indexing
  unrealizable, even with some automated support.

• Even such simple indexing by the most powerful
  robot for major web search engines only covers a
  small percentage of the total web. But usage and
  problem dispensation among various software
  elements is highly rugged, which is also shown to
  be true among various web contents.
• Therefore, some type of selective testing is
  needed to focus on highly-used and problematic
  areas to assure maximal web site reliability
  improvement.
