Abstract. This paper proposes an approach that can be used to test the stability
and other related attribute of Network information, and that can be easily en-
hanced to assess other quality attributes. The framework is based on rules for
test case generation that are designed by, firstly, analyzing WSDL document to
know what faults could affect the stability quality attribute of Network informa-
tion, and secondly, using the fault-based testing techniques to detect such faults.
A proof of concept tool that depends on these rules has been implemented in
order to assess the usefulness of the rules in detecting stability faults in different
Network information platforms.
Keywords: SOAP, Testing Approach, Quality Attributes, Assessing, generation

1 Introduction
Network information [6] are considered a new paradigm in building software applica-
tions based on the Internet and open standards. This paradigm has changed the way
we look at the Internet from being a repository of data into a repository of Services.
By using Network information, companies can ensure that their applications will
communicate with those of their business partners and customers even if they are us-
ing different programming language or platforms.
A problem that limits the growth of Network information is the lack or trustwor-
thiness by the Service Requesters because they can only see the WSDL document but
not the implementation or source code.
Testing can be used to solve this problem; by assessing the quality attributes of a
Web Service under test, the confidence or the trustworthiness of the requesters in-
crease or decrease according to the test results. This will also help requesters to
choose between Network information that are doing the same task.
However, Network information testing still face many problems like the unavail-
ability of the source code to the Service Requesters and that the traditional testing
technique do not cope with the new characteristics introduced by Network informa-
tion standards. This paper introduces an approach that can participate in solving these
problems. This approach is based on analyzing WSDL documents in order to generate
