Reboot Testing for Modern Software Development

The testing industry must evolve and adapt to keep pace with modern software engineering.

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.

Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...
Alibaba, the world’s largest ecommerce provider, has pumped over a $1 billion into its subsidiary, Aliya, a cloud services provider. This is perhaps one of the biggest moments in the global Cloud Wars that signals the entry of China into the main arena. Here is why this matters. The cloud industry worldwide is being propelled into fast growth by tremendous demand for cloud computing services. Cloud, which is highly scalable and offers low investment and high computational capabilities to end us...
The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?
At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices.
