OpenTAP and Security Testing I - The Role of Test Automation

Cybersecurity sits at top of mind for IT professionals and these days, even for device manufacturers.  Cybersecurity testing includes a range of assessments and evaluations that focus on various aspects of security posture. These tests help identify vulnerabilities, weaknesses, and potential threats in systems, networks, and applications.

This first blog in a series calls out the various types of cybersecurity testing and how and if OpenTAP can facilitate and control each.

OpenTAP and the Internet of Things

Test automation and the Internet of Things (IoT) are distinct but interconnected domains The relationship between the two primarily lies in how test automation can be used to ensure the quality and reliability of IoT devices and systems.

In complementary fashion, modern intelligent, connected test instruments share attributes with other IoT edge devices – sensor-centric mono-functionality, remote access and control, cloud-based analytics, etc. – and so themselves participate in the Internet of Things.

Test Automation, AI and ML

Artificial Intelligence (AI) and Machine Learning (ML) are bringing new functionality to applications across information technology. Projects like ChatGPT that employ large language models, and various image creation engines garner popular attention, but AI and ML have potential to enhance test and test automation in myriad ways.

This blog explores complementary aspects of enhancing test and test automation with artificial intelligence and machine learning, in particular, how AI and ML can enhance test and test automation.

Building and Running OpenTAP on ARM-based Systems

This blog demonstrates how hosting the OpenTAP test automation engine itself on ARM-based systems is a relatively straightforward task. Since OpenTAP is built with .NET, it enjoys the hardware abstraction provided by the Microsoft application framework, with very few hardware-specific dependencies or idiosyncrasies. As examples, the blog shows how to target an Apple M1 host running Ubuntu Linux, an ARM64-based Raspberry Pi system, and an M1 Pro-based MacBook Pro running MacOS.

The Importance of Collaboration in Testing and Test Automation

Testing and test automation usually conjure visions of software and hardware under test on a test bench in a lab or on a production line. The involvement of human actors can seem quite secondary and distant from executing test plans and running through test steps.

In practice, test engineering is a very human endeavor: humans design the systems under test, specify testing criteria, implement test code and evaluate test results. And they don't perform these tasks in isolation.

OpenTAP in Education: Controlling Cobots at U.C. Santa Cruz

Every year for the last three Keysight has collaborated with faculty at the University of California Santa Cruz (UCSC) Baskin Engineering School to sponsor one or more senior projects in test automation. This year, that project focused on utilizing OpenTAP and OpenTAP plugins to control a collaborative industrial robot arm (cobot). The UCSC team faced a range of educational, logistical and technical challenges and met each with intelligence and aplomb.

Total Cost of Ownership for Test Automation - Part V

Cost calculation for legacy in-house test automation platforms is seldom a simple task; costs for in-house test automation are embedded in s/w and h/w development budgets. if itemized at all, testing costs fall into product and QA/QC budgets But the cost of developing and maintaining a test platform is almost never itemized because it’s not part of the product specification.

Total Cost of Ownership for Test Automation - Part IV

This fourth blog in our series on Total Cost of Owner examines costs for Support and Maintenance, Downtime, Compliance and End of Life.

Supporting open source project code offers greater freedom of choice and reduced lock-in to a single vendor. In many cases, the organization responsible for launching, distributing and/or maintaining the project code also offers commercial-quality distributions and professional support.

Total Cost of Ownership for Test Automation - Part III

In our series about factors that influence Total Cost of Ownership (TCO) for open source test automation, we are investigating how those costs differ from proprietary software, including in-house and commercial platforms. This third blog examines paths from legacy, including proofs-of-concept, training, integration and operationalization.

Total Cost of Ownership for Test Automation - Part II

This second blog in our series examines the factors that influence Total Cost of Ownership (TCO) for test automation. The blog focuses on how those costs differ from proprietary software, whether sourced commercially, created in-house, or built from open source. In this blog, we look at Acquisition Costs, in particular, the eternal Make vs. Buy decision facing IT and engineering management.

Contributing plugins to the OpenTAP Project

OpenTAP makes customization easy by offering a plugin-based architecture. The OpenTAP project includes a range of ready-to-use plugins to support instruments, DUTs, user interfaces, results listeners and more. Plugins also originate from OpenTAP ecosystem participants - hardware manufacturers, software suppliers and end-users. If you have developed an OpenTAP plugin and are eager to share it with other ecosystem participants, read this blog to understand how to host your plugin in the OpenTAP project repository.
