iTKO Virtualizes SOA Testing
LISA 3.6 has broadened load-testing capabilities
By David Worthington

October 1, 2007 — Virtualization isn’t just about hardware, believes testing provider iTKO, which has expanded its software's ability to simulate load testing by using virtualized services.

iTKO released version 3.6 of its LISA SOA testing framework on Aug. 30. LISA leverages virtualization to run tests that invoke and verify at each tier of the architecture. It virtualizes the behavior of services to lower the number of test beds, and reduces licensing costs and contention on hardware.

The upgrade adds several feature enhancements that include an expanded set of load patterns for simulating user traffic, simulation patterns that run from multiple servers and locations, more automated pacing of transactions for test cases, and test synchronization.

Test steps can now be aggregated into reporting groups so that test workflows match business processes. iTKO has also incorporated additional ways to generate reports, and then export, manage and use test data from complex test suites by interacting with databases.

John Michelsen, founder and chief architect of iTKO, said that the next major release of LISA would make broader use of virtualization. “As [Business Process Management Systems] become applications, we want to be the best application,” he said, noting that the pairing of SOA and virtualization technologies was a match made in heaven.

iTKO also intends to provide more functionality around SOA governance runtime policy. Critical Path Tracer is a new component being developed to inspect environments and perform functional and performance verifications, said Michelsen.

“SOA load testing is a very different task than conventional software load testing on the client,” Jason Bloomberg, senior analyst at ZapThink, said in a statement. “As such, SOA testing deserves its own tool set that can invoke and verify functionality at every layer of the architecture, and do so at load, throughout the design, change, and runtime phases.”
