“Hunting Bugs with a Shotgun and a Rifle” Published

Colts Neck, NJ, 25 July 2014 – The IEEE has published the proceedings of the The 3rd International Workshop on Combinatorial Testing, including Functional Dependence and Equivalence Class Factors in Combinatorial Test Designs. This paper is also known as “Hunting Bugs with a Shotgun and a Rifle” because it compares two approaches to combinatorial testing. The shotgun approach mixes the test factor combinations leading to different types of test results. The rifle approach focuses test cases on a single type of result (an equivalence class). Formulas to assess coverage of expected results are given in the paper. The author, George Sherwood, noted the formulas depend on relations among the test factors, not the generated test cases. So coverage can be assessed before, or without, generating the test cases.

“While the two approaches can be adopted as needed, there are significant differences,” Sherwood said. “The rifle approach directs test cases to each type of result, for efficient testing with fewer cases. But the expected results need to be known. When the system is not well specified, the shotgun approach may be required.” Slides presented at the workshop are available at the Testcover.com background page.

Testcover.com introduces cloud-based test solution breakthrough: self- management for group subscriptions

Colts Neck, NJ, USA, 11 June 2011 – Testcover.com has introduced self-management for customers with group subscriptions. The company, with several large global multinational corporations as customers, developed and deployed the new group administration interface to serve the needs of administrators with large groups of Testcover.com users.

Testcover.com CEO George Sherwood said, “We see this capability as a significant enhancement to the convenience and efficiency of our service. Now customers can opt in to self-management and get the highest levels of visibility and control.” Sherwood explained a popular feature of self-management: “Customers with multiple software engineers use our group subscriptions to simplify billing and reduce costs. They purchase a number of subscription activation codes for individual engineers in the group. These customers often have development groups that change, with members joining or leaving independent of any overall subscription period, and customers expect a cloud service to handle their changing needs simply and efficiently.” Testcover.com’s new self-management provides these customers the means to assign an unused activation code to an engineer joining the group, and start the subscription at that time. If an engineer leaves, the unused subscription time can be retained in a new activation code for the replacement.

Use of Testcover.com’s new group administration interface is optional, and there is no additional cost for it. The interface allows a designated user to access summary information about the group and to perform several management tasks:

  • List available subscription activation codes – show which activation codes have not been used yet.
  • Register a new user – select an activation code to register a new user in forms that are prepopulated with group information.
  • List active users – show current users and their respective renewal dates.
  • Reset password for an active user – choose a new password for an active user and email it to that user.
  • Renew subscriptions for active users – extend service for selected users.
  • Suspend subscriptions for active users – end service for selected users and transfer remaining subscription time to new activation codes.
  • Purchase new subscriptions – generate subscription activation codes for new users.

Testcover.com renders industry-leading cloud-based test solution 25% faster

Deploys optimized pairwise search algorithm

Colts Neck, NJ, USA, 11 June 2011 – Testcover.com has announced a performance improvement of up to 25% in its industry-leading cloud-based test case generator service. This improvement is available at no additional cost to all users. Current response time examples are given on the Testcover.com performance statistics page.

Proprietary research conducted by Testcover.com last year found significant response time improvements from an optimization of its search algorithm. Response time was reduced in small search spaces as well as large ones, with greater reductions in the larger search spaces. Testcover.com CEO George Sherwood said, “Users running typical jobs may or may not notice the improvement because our previous response times with the service were so quick, but we have now achieved response time reductions of 25% for large requests.”

The performance of a pairwise test case generator depends on two essential components: the number of test cases produced and the response time for generating them. Practical software engineering tools require an optimal balance between the two. Testcover.com runs an ongoing research program to reduce the number of test cases generated by the service and employs state-of-the art engineering techniques for prompt response times.

Sherwood also noted, “This enhancement reinforces our commitment to continual performance improvement–reducing the number of test cases as well as the response time to generate them.”

Innovation Spotlight shines on Testcover.com at TM Forum’s Management World 2011

Selection to Stratecast’s “Rat Pack/10 to Watch for 2011” leads to appearance at global event

Colts Neck, NJ, USA and Dublin, Ireland | 19 May 2011 – Testcover.com will be in the Innovation Spotlight at the TM Forum’s Management World 2011 in Dublin, Ireland, 23-26 May. Testcover.com was chosen to appear based on its selection by research & consulting firm Stratecast, a division of Frost & Sullivan, to its “OSS/BSS Rat Pack: 10 to Watch for 2011” report published in December 2010. Stratecast publishes this report annually, selecting 10 companies to watch in the coming year that, per Stratecast, “share characteristics with the original Rat Pack team of Hollywood actors from the mid-1950s including Frank Sinatra, Dean Martin, Sammy Davis Jr., Peter Lawford and Joey Bishop. Like its namesake, the companies included in this report are solid performers who work well, both individually and as an ensemble through partnerships, to satisfy the needs of communications service providers (CSPs) worldwide.”

In his remarks at the Innovation Spotlight, Testcover.com CEO George Sherwood is expected to highlight the versatility, performance and Cloud features of Testcover.com’s automated test design service. In a recent interview, Sherwood said: “Testcover.com is meeting the growing need for test design of complex systems, with features and performance for practicing software engineers building real systems. We provide Testcover.com as a Cloud service for easy, up-to-date use, everywhere.”

One example Sherwood is expected to cite at the event illustrates how Testcover.com’s pairwise (or all-pairs) advantage translates into real-world benefit. Faced with more than 205 trillion possible test cases for a feature with 30 inputs, a company was able to cover all 3,915 pairs of test values with only 18 test cases. Pairwise test designs from Testcover.com use far fewer test cases than random selection for comparable coverage.

Sherwood worked 25 years at Bell Labs and AT&T Labs on a variety of hardware, software and service development projects. He is a former district manager in the IP Services Delivery Division at AT&T Labs, responsible for the development of Broadband ISP services for leading communications service providers. Sherwood is the inventor of the Constrained Array Test System (CATS), the first pairwise testing tool to use a so-called “greedy search” algorithm. He has championed innovative test case reduction, faster performance and improved usability in test design tools.
