SOA Testing.. Whats the difference?

Every one of us is hearing about SOA every where… But is SOA testing same/similar to traditional testing?If different how and where? Tools available in market, which one is best, which tool to buy? Many Qualms are present… Above that is Testing SOA Really important!!!

Hmmm let me think… every element built by humans needs to be tested. More ever if elements are hidden or Processes internally then testing is must..Hence SOA testing is Very critical.
