Traditional methods of software development went over the waterfall in a barrel and smashed on the rocks below. The Agile Manifesto was written more than a decade ago. Agile adoption has worked wonders for software development. New products leap from concept to market faster than ever before.
Software updates are expected to roll out quickly into live products without disruption, the cloud is growing ever larger, and mobile technology is impacting heavily on how applications are developed. Feedback from the end user informs the design. Documentation and planning are sidelined in favor of flexibility and speed. It's a trend that has powered the app revolution, but it's so focused on developers that testing has been forgotten.
Clear Out the Old
New builds come thick and fast nowadays. It has become much tougher to estimate the required resources to properly test a project at the outset and, even if you could create an accurate estimation, it would soon be rendered obsolete.
It's not feasible to have small, fixed-size teams of testers covering an Agile project. As each new sprint introduces new features, the amount of work grows. Testers must check the new functionality, but they also have to verify bug fixes and complete regression testing. If you don't scale the team up as time wears on, or develop automated tests to reduce the workload, then things will start to slip.
Building a New Approach
The Agile mindset in the developer community has given birth to countless methodologies, supported by books and dedicated software tools. The discussion and support is lacking in the testing industry and that needs to change. Testers need software tools that are up to the job. Test management should cover the entire lifecycle of testing. An adjunct of the project management software designed for developers is not going to fulfill their needs.
The Agile age demands skilled testers equipped with tools that enable them to record tests step-by-step, link user stories and test cases, automate scripts where necessary, export and import bugs, and extract an overview of testing progress.
By developing exploratory testing skills and employing automation where it makes economic sense, testers can rise to the challenges of modern software development.
Employ Automation When Appropriate
The real value of testers is in their ability to test drive new features and validate bugs. You don't want them engaged in a regression testing slog. It means duplicating work and it's dull and repetitive for the testers. You won't get maximum value from your resources that way.
Automating regression testing can free up testers to focus where you want them. It's not easy, but with the right plan it can work. You can't create your test cases and scripts until the code is deployed. What you can do is record the testing process as your testers work through the new build and then use the steps captured to generate new test cases that can serve as the basis for automated regression testing on the next release.
Tester as End User
In the days of waterfall development, testers would have extensive documentation and requirements to pore over in order to create a detailed test plan. All the test cases would be prepared and ready to execute when the build arrived. That's often not possible with agile development. If the developers are going to adopt an agile mindset, then testers need to do likewise.
Exploratory testing can be employed to examine each new set of features when the build lands. Testers can record their steps and then edit them to create a solid base for regression testing. A core set of test cases can be fully scripted and automated. This process requires an evaluation of where the most value can be derived and that decision should be informed by what you know is coming down the pipeline from the developers.
For this to work testers must be included in the development process early and often. They need to be in Scrum meetings, they need to understand the user stories, and they must be empowered to contribute and ask questions. Testers can obviously learn a lot from developers on the project, but they should also be able to ask questions on the business side. If they can truly emulate the intended audience for the softwar, they can make a bigger contribution toward ensuring that it hits the mark.
Let's Make a Change
If we accept that the development landscape has changed irreversibly, we can really focus on ways to empower testers. Adopt an Agile mindset, but apply it from a testing perspective. Seek out new processes and new tools that really deliver the functionality and structure testers need in order to add value in a timely manner. Encourage more communication and deeper involvement in projects so that testers can emulate your end users accurately and help to ensure that expectations are met. Modern software development is still evolving and testing needs to evolve along with it.
"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

We are always online. We access our data, our finances, work, and various services on the Internet. But we live in a congested world of information in which the roads were built two decades ago. The quest for better, faster Internet routing has been around for a decade, but nobody solved this problem. We’ve seen band-aid approaches like CDNs that attack a niche's slice of static content part of the Internet, but that’s it. It does not address the dynamic services-based Internet of today. It does...

What happens when the different parts of a vehicle become smarter than the vehicle itself? As we move toward the era of smart everything, hundreds of entities in a vehicle that communicate with each other, the vehicle and external systems create a need for identity orchestration so that all entities work as a conglomerate. Much like an orchestra without a conductor, without the ability to secure, control, and connect the link between a vehicle’s head unit, devices, and systems and to manage the ...

Major trends and emerging technologies – from virtual reality and IoT, to Big Data and algorithms – are helping organizations innovate in the digital era. However, to create real business value, IT must think beyond the ‘what’ of digital transformation to the ‘how’ to harness emerging trends, innovation and disruption. Architecture is the key that underpins and ties all these efforts together. In the digital age, it’s important to invest in architecture, extend the enterprise footprint to the cl...
