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.
