Four testing and quality assurance vendors, Mindreef, Solstice Software, Parasoft and iTKO, this week joined SOA Link, an industry initiative geared toward SOA governance.SOA Link is driven by Infravio and also has featured members such as Hewlett-Packard, Iona and JBoss. Mindreef intends for its products to help assure service quality and reliability as part of SOA Link. The company offers Mindreef SOAPscope Server, a solution for SOA system component testing. Parasoft offers automated error prevention products for software development and is looking to SOA Link to assist in boosting quality. The company offers an “SOA-aware testing framework,” called Parasoft SOAtest. Solstice Software provides Solstice Integra Suite, for end-to-end integration and testing. The company plans to identify governance and testing use cases as part of SOA Link.SOA testing vendor iTKO also joined SOA Link.
