How to accelerate your release cycles with Agile Testing



Agile testing needs to be aligned as per the business objectives of enterprises for accelerating the software release cycles. The processes to achieve the same include proper planning, meeting expectations, and testing early and frequently.

Staying competitive in today’s world of business requires consistent delivery of customer satisfaction through your products or services. If quality has emerged as a differentiator for enterprises to expand their customer base, enabling faster release cycles arguably comes next. With the traditional Software Development Life Cycle (SDLC) encompassing the waterfall method of testing, achieving quality and faster time to market has become difficult. This brings Agile testing into the equation where development and testing take place simultaneously instead of operating in their respective siloes.

How agile testing approach can accelerate the software release cycle

In the Agile form of software development life cycle of iterative development procedure, the requirements generate mainly from the end-customers and testing teams. The Agile software testing methodology is aligned to the customer requirements. The Agile application testing aims at delivering a product free of glitches and quickly to the market.

Further, agile testing services do not consider testing as a separate process but an integral part of the development cycle. Here, developers and testers work in cohesion as a single entity called sprint. These services are distinct from traditional testing comprising logging glitches, checking metrics, and writing detailed test cases. In agile methodology, instead of testing the code post development, it is done early and frequently. In fact, the testing team is engaged with testing and integration of sub-systems and features. It is observed that Agile practices do not always generate the likely outcomes enterprises set out to achieve. It is due to the fact that enterprises often embrace agile practices without adapting them to their IT environments, workflows, culture, or architecture. This means enterprises, while adopting agile, should be guided by their goals. Among the goals, the feedback loop needs to be shortened to fix the glitches quickly.

The agile methodology aims at delivering quality software at frequent intervals, speedily and consistently. This calls for better collaboration, flexibility, and transparency among the development and testing teams. The agile testing experts should ensure quality becomes everyone’s responsibility (both developers and testers). To reach the goal of identifying (and redressing) glitches early, testing should be conducted early and often in the SDLC.

However, since the process needs to be speedy and efficient, test automation becomes the key. It ensures copious lines of codes and variables are checked for glitches and integration against expected outcomes. Test automation prevents the code from showing unexpected results, defects, regressions, and cost escalation due to refactoring later. The metrics tell the detailed scope of testing comprising code coverage, the percentage of test automation coverage area, and the impact of glitches on the end-users. Switching between the old and new codes using toggles must be coupled with forward and backward compatibility. This is to ensure the code is not broken while enabling new functionalities. The entire process requires thorough architecture planning and deep knowledge of the code base.

A Microservices architecture entails breaking up the code into smaller units and assigning them to different teams. The final application can be built using any combination of the microservices provided the interfaces are properly defined and maintained. Since the microservices architecture requires less maintenance, it helps to improve the consistency and speed of software delivery.

How did we increase testing efficiency for a global technology enterprise?


A leading multi-national IT corporation reached out to us regarding severe testing inefficiencies in their Agile cycles. They were facing a serious crunch of the required skillset and were somehow managing with a limited pool of resources. Their business deliverables demanded highest quality in a rapidly changing Agile environment, which was rendered with inconsistent processes across the scrums. They had parallel scrum teams developed at multiple locations, which resulted in challenges in achieving test coverage and agility in communication with virtual teams.

The Agile mess that they had was screaming the sorry state of their Agile testing plan. Evidently, they needed a solid testing strategy to be designed, executed, and integrated with their Agile methodology.

We set up test environments at the developer’s locations to be virtually accessible to our off-shore testing team for revalidation in critical situations. A Quality Control dashboard was developed and maintained with interface to exchange server. The dashboard increased the scrum-level transparency and offered better control. We designed end-to-end processes and defined entry and exit criteria for all stages.

Adopting best practices across scrum teams helped achieve consistency across the parallel testing processes and cycles. A well-defined regression, mini regression, and automation coverage was achieved with the help of our solid test strategy supported by maintainable supporting artifacts. By leveraging automation techniques to cover at code level and capturing key inputs for high volumes of data for dozens of sites, we assisted with better planning. We established a disciplined communication model which ensured a seamless transition of tasks between scrum master and scrum leads.



Conclusion

To accelerate your software release cycles with the agile testing strategy, the entire process needs to move to a CI/CD pipeline. Implementing agile is similar to any change process involving challenges, bottlenecks, as well as, opportunities. If enterprises are sure about their objectives and the way to achieve them, the challenges would become opportunities for learning.

The definition of agile can mean different things to different people. However, it needs to be implemented as per the requirements and working pace of organizations. In pursuance of agile, there can be challenges in terms of aligning people and processes. In case of failures, it is worthwhile to remember that agile can engender failures but the same should be an opportunity to learn. Failures are acceptable provided the process of deployment is iterative and continuous.

How Test Automation helps Agile to be successful?



To meet the stringent quality requirements of complex applications, the Software Development Life Cycle has changed. If earlier, the waterfall was the preferred model with testing done at the end of development, it has given way to Agile today. This is because the waterfall model suffered from a lot of inconsistencies and did not deliver the right results. Also, it increased the cost of software development and testing for businesses. The need for Agile was felt due to the growing complexity of software applications. As the new software applications come with endpoints that interface with third-party databases, servers, or sites, the quantum of vulnerabilities has increased. If not plugged in time, once these applications are out in the market, they can be exploited by hackers leading to severe consequences for the users.
With Agile, it has become easy to detect glitches and vulnerabilities early on in the software development pipeline. Also, to keep pace with shorter release cycles, enterprises are adopting Agile test automation. This is to ensure the software conforms to the exacting standards of quality. Further, with plenty of features being added to the software in every sprint, developers need to ensure they do not affect the existing functionalities. Also, as the sprint is of a shorter duration, it is not possible to test and execute the entire software suite every time a feature is added. This is where Agile test automation can help by running the codes iteratively.

Why Agile development needs automation?
The Agile model entails the development, testing, and delivery of glitch-free software products within fast turnarounds. Since the process can involve repeated changes, a robust test automation strategy should be put in place. For Agile testers, there are several challenges to be addressed with Agile test automation.

Challenges for Agile testing
Even though adopting an Agile testing framework delivers a string of positive outcomes, it can entail some challenges too. These include
Inadequate test coverage: During the later sprints when a number of features are added to the build, the testers get lesser time to test them and analyze their impact. In such conditions, a few user stories are left untested with the hope that they would not affect the release. However, by automating the Agile application testing process, the build can be put through a regression testing exercise to achieve assured quality.
Frequent build leading to cracked code: In Agile, there can be instances of frequent code changes due to the addition of features to the build. These changes can lead to cracked codes, especially during the integration phase. Further, to implement a continuous integration and deployment pipeline (CI/CD), the Agile testing experts ought to implement test automation.
Performance issues: It can often be the case when improving the functionality of an app can end up complicating it further. Since every change can lead to an increase in the volume of codes, the performance of the app can take a hit. However, conducting Agile performance testing using automation tools can identify the performance issues.
Compatibility issues: Any software of the day should be checked for its compatibility across devices, operating platforms, browsers, and networks. Ideally, testers should ensure the seamless run of software across devices. An automated test run can check for glitches or vulnerabilities in the endpoints and APIs, and make sure the compatibility issues are sorted.
API testing: A web or mobile app involves the implementation of complex APIs, the quality of which is often overlooked. Automation testing tools such as LambdaTest can help Agile testers to overcome such issues.

Things to automate in Agile
When it comes to introducing automation in testing, areas like regression testing or smoke testing take the cake. However, these are just the top layers of the build, which can be insufficient as far as ensuring the quality of the software is concerned. The other areas where test automation can be implemented are
·         Builds and deployments
·         Unit tests
·         Non-functional testing
·         API testing
·         GUI testing
·         Repetitive tasks like data comparisons

Benefits of test automation
Agile development can be benefited from automated testing in a number of ways related to performance, portability, versioning, reliability, usability, and speed, among others. The benefits include
·         Enhanced quality
·         Quick turnaround
·         Repeat execution
·         Seamless performance
·         Better collaboration

Conclusion
The Agile testing approach can lead enterprises to create a better software development pipeline. Its success is underpinned on the level of implementing test automation. The automation-led Agile methodology combined with DevOps has the potential to improve the quality of software and deliver great user experiences.
