The Role of DevOps in Software Testing: A Reality Check

Ankita Hariyani

Well, with Digital Revolution pacing at full speed ubiquitous access to digital content and seamless user experience has become indispensable. For instance, your stock market application that crashes and gets inaccessible for hours could be an unpleasant experience that will prompt an uninstall and a negative review. There are chances that you might want to check your share market trend not just once but possibly every hour across any device. This is prerequisite for any kind of application today.

If you’re an IT service provider, the stakes are much higher. It is important for you to scale your service delivery capacity in a sustainable way. Whether it’s a broken code or a nasty bug, it all needs to be fixed at once – not in weeks or even days. However, faster delivery of application without compromising quality is challenging for operations, application development and delivery teams.

The advent of Agile delivery model did pave the way for faster delivery of software, but the development and operations team still worked in silos.

Unexpected things happen

What happens when you have teams but they’re not good at collaboration? There are delays, bottlenecks and it becomes a pain in the neck to solve problems quickly and efficiently.

The mounting pressure on developers and testers to deliver scalable software and applications meant four things – Speed, Quality, Consistency and Security. Luckily, this gave rise to the DevOps army!

DevOps = Development + Operations.

Coined in 2009 by Patrick Debois, DevOps is the next-generation Agile software testing approach that creates a unified platform to enhance the software delivery process.

DevOps works with the discipline, coordination and consistency of a fleet of warriors.

In a DevOps environment, the responsibility of quality, compliance and security does not rest solely on the operations team. Instead, it is collectively owned by all the stakeholders involved in the entire service delivery process.

DevOps software lifecycle shifts everything to the left - beginning with testing as early as practical in the lifecycle. It relies on automation of everything while continuously enhancing it in the early stages of SDLC.

It’s similar to being on the battlefield and improvising your strategic approach with helpful insights while manual and repetitive tasks are taken care of by an army of hi-tech automated gadgets.

What influences the DevOps adoption?

Today, DevOps is the need of the hour. Particularly, the rise of digital technologies such as IOT, AI, Analytics and Cloud has forced every software-driven business to constantly redefine their software development and testing strategies.

“71% of companies are investigating, planning or actively moving to a more DevOps focused business.”

One of the major reasons behind the adoption of DevOps is to accelerate the delivery of software by continuous integration and deployment while reducing lead time.

IT performance metrics

Top-performing organizations like Netflix and Amazon utilize DevOps practices to ensure that their software is fully tested, committed and deployed to production. In fact, Netflix could reduce its software deployment time by just sixteen minutes, that sounds impossible, but it is provided you have the right DevOps forces to assist you.

Last year news spelled out that the famous car manufacturer, AUDI had to postpone the release of its first electric SUV 4 weeks later than they actually planned due to a software development issue. That’s because the embedding of the IoT component in Cars with seamless functioning software has now become a critical part of the auto business.

Such software glitches show us why before entering the Market battlefield we need to emphasize as much as possible on quality assurance and software testing. Traditional software testing involves testing a build only after the software is developed by the development teams. While DevOps enables a cross-functional team to work in collaboration to deliver with maximum speed and agility. Agility with vision wins battles.

How success is measured

Irrespective of your overall business offerings, as a business you end up delivering software services in order to provide a full range of core business services. Your product is an integral part of other business’ operations. Thus, software testing is crucial, and DevOps is conducive to this approach.

3 Ways DevOps Is Playing Major Role in Software Testing
1. Quick Response Time

Trunk-based development combined with automation testing provides a quick response from the development to production while ensuring the changes are done in sequence. Since testing is done in an integrated environment, it enables faster iteration and feedback on quality build while avoiding potential development conflicts.

DevOps facilitates continuous testing in a stable development environment allowing teams to focus on identifying and improving other quality indicators before final deployment.

2. Continuous Security

Previously, security and compliance were a part of the post-development phase. Adopting DevOps integrates information security in everyone's task as an automated deployment pipeline. In addition to that, running static and dynamic analysis allows testing functional behavior, run-time behaviors, response time and malicious code while the program is in operation. This practice helps in proactively identifying security issues in the production environment.

3. Chaos Engineering

Software testing is shifting its focus from functional requirements to identifying and understanding anonymous non-functional requirements. Chaos engineering is an approach to take random destructive action in a production environment just to test the reliability of the environment.  

Generating chaos means randomly killing operation instances and observing system behavior. This practice brings more reliability into system and allows your team to learn how to repair a system when natural chaos occurs like network latency or shutting off access to the external system.

DevOps Software testing isn't limited to a specific team or a part of an application. It is a continuous process whether in a deployment pipeline, for security compliance, fault detection or functional testing to ensure the software is regression-free.
