Designing and developing a testbed to evaluate the features of web service properties and their service interfaces in a distributed web service environment. This testbed interface helps the clients and their tools to build automatically with the corresponding web services and to identify its related issues in which it can communicate and cooperate among services in a distributed environment. By establishing set of policy and preferences for relevant supporting tools to evaluate the semantic technology of service and enhancing the tuning features by avoiding interoperability among web services. A light weighted application having unique and specific structure for designing testbed for istributed web service environment (DTDWS) with a build in concepts encoded with XML (Extensible Mark-up Language). This proposal breed a trustful zone in a distributed environment by an automated simulation,composition and testing techniques are put into service. Many service conflicts are resolved in a timely and consistent approach all the way through our proposed testbed .
