“ When you are delivering spatial web services on behalf of 20 government agencies to more than a 1000 organisations running their own spatial systems, you need standards.”

“Using the internationally recognised OGC and ISO standards for both the architecture and web services has been essential to our success.“

Client Testing Future Work

• Need a set of operations for a client to be tested. Commonly specifications define the server side.

• If the client doesn't performed all the expected operations then the report should say so. Currently only reports what is being requested

• The report should also tell about operations that the client performed but that were not tested.

SummarySummary

• The world is full of services and encodings following OGC Standards (WFS, WMS, KMLS etc..)

• We need to test to better achieve interoperability.

• TEAM Engine is a state of art web testing tool. IT IS OPEN SOURCE and JAVA.

• CTL is a flexible language used for testing.• We have developed initial approach for Client

Testing• Your participation is very welcome !
