Four Ways to Improve Your Agile Testing Automation Processes
Agile software development is slowly but surely becoming the norm for a significant contingency of software developers. What used to be rigid, step-by-step processes that were siloed between specific teams have transformed into a collaborative, adaptive methodology that ultimately leads to the creation of superior solutions.
As an integral component of software development, agile test management has also been evolving to be more accommodating to agile processes. Testing automation in particular is still coming into its role as an agile tool and, for some teams, this may create unique challenges. Still, by taking the following into consideration, testing teams can reap all the benefits of testing automation in an agile environment.
1. Strong communication
Contrary to the notion of an open workspace in which different teams freely walk up to one another with observations and questions, many testing teams still work in different offices, sometimes even in different parts of the world. According to TechTarget contributor Francis Miers, nearly 60 percent of all agile testing teams are scattered across the map. On the surface, this may seem contradictory. However, the problem with traditional testing methodologies was not that people weren't working in the same room, but that they weren't communicating effectively. As a result, teams were relatively blind to what happened to a product before and after it ended up on their rotation.
For the most part, telecommunications and cloud sharing capabilities have made it possible for even disparate testers to stay in touch with each other and with other teams. This communication is essential for fostering agile testing methodologies and must not be shirked. As the experts, test managers can certainly take a leading role in testing automation, but only by collaborating with developers can they have a solid understanding of how to plan for regression tests, and where testing automation needs to occur. The key here is to create a transparent, collaborative testing life cycle.
2. Select the right tools for the job
Trying to use waterfall testing tools for an agile project is like trying to fit a square peg in a round hole: Even if you somehow manage to do it, corners will have to be cut, and the end result won't be ideal. It is for this reason that TechTarget contributor Nari Kannan recommended leveraging testing tools that can accommodate the speed of agile. This includes the ability for scripts to be written and revised swiftly in order to support each new iteration of the project. Kannan also pointed out that agile testing methodologies should be imbued with the ability to test for scenarios rather than standard, black and white inputs.
"Support for automated testing scenarios may be much more useful when using Agile development methodologies rather than support for specified inputs and expected outputs as in traditional automated testing tools," Kannan wrote. "Many more automated tests for scenarios become reusable between iterations, so re-scripting between iterations becomes easier."
3. Automate generously, but intelligently
Everything that can be automated should be automated - assuming it makes sense to automate it. The majority of regression tests, for instance, are inherently redundant. They ensure that an alteration or add-on will play nice with everything that came before it, and this allows for innovation on the fly. Automation integration saves time here by eliminating the need to manually go back through the steps every time changes are applied. In addition to guaranteeing that regression tests actually happen, the risk of human error is significantly reduced.
That said, deciding what tests to automate and how exactly to automate them must be a very hands-on process. These tests don't necessarily have to run manually on the first go-around, but they should be intelligently integrated, which consists of deciding how they should interact with the scripts before they are set in motion. In theory, it's wise to seize every opportunity for test automation. In practice, it's even wiser to make sure that automated tests are thoughtfully deployed and that they rely on test metrics that actually matter.
4. Manual testing isn't going anywhere
Going off number three, it won't always make sense to automate every test case. Even with exploratory testing that can help testers probe for possible outcomes of specific scenarios, there will be situations in which unforeseen manual testing will be the only sure-fire way to thoroughly vet certain software features. This is especially true when it comes to optimizing the user experience. Even with adaptive design and smarter navigation, the ever-increasing number of platforms, particularly in the form of mobile devices, may result in clunky UX that an automated test cannot readily detect.
The good news here is that if the need for a certain manual test seems to arise more frequently, it can subsequently be automated. Manual testing is great for unique or anomalous user scenarios. But once the need for this test becomes recurring, it may make more sense to automate it, and therein lies the beauty of agile testing methodologies. They're as flexible as you need them to be.

Virtualization over the past years has become a key strategy for IT to acquire multi-tenancy, increase utilization, develop elasticity and improve security. And virtual machines (VMs) are quickly becoming a main vehicle for developing and deploying applications. The introduction of containers seems to be bringing another and perhaps overlapped solution for achieving the same above-mentioned benefits. Are a container and a virtual machine fundamentally the same or different? And how? Is one technically superior to the other? What about performance and security? Does IT need either one, or both?

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor - all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organizations must focus on what is most relevant to deliver value, reduce IT complexity, create more repeatable agile-based processes and leverage increasingly secure and stable, cloud-based infrastructure platforms.

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ability. Many are unable to effectively engage and inspire, creating forward momentum in the direction of desired change. Renowned for its approach to leadership and emphasis on their people, organizations increasingly look to our military for insight into these challenges.

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.
