Test Automation In DevOps For Expediting Software Development

How DevOps Uses Test Automation Tools to Accelerate Software Development

The goal of DevOps is to build faster, effective, and responsive applications by bringing together the development team and the operations team. It is a cultural shift to remove all barriers between Dev and Ops and provide shorter as well as frequent software deliveries, thus enabling organizations to respond in a much agile manner with respect to the constantly changing customer demands and expectations.

In a nutshell, DevOps via effective collaboration, communication, streamlined delivery, and automation of processes will accelerate software development in the following key ways:

Faster time to market
Reduces risks of failures in each release
Enhances error fixing and recovery time
Improves the checking process efficiency
Speeds up the rate of change
Allows managers to make improved and effective trade-off decisions
Enables rapid and continuous feedback
Offers flawless continuity throughout the Software Development Lifecycle

Testing in DevOps starts from the very beginning of application development and hence it is important to make sure that the development team and the operations team work closely with each other to ensure continuous integration and prompt delivery by continuous testing and monitoring.

Automation Testing in a DevOps Environment

DevOps is categorized into the following 4 processes:

Continuous Integration
Continuous Delivery
Continuous Testing
Continuous Monitoring

The testing teams require to align their test design, automation, as well as test case development along with DevOps to ensure that the frequent changes made have not affected the final product.

Unlike the traditional approach, automation testing in a DevOps environment requires moving test automation scripts to a control tool which is of an enterprise version. This system of centralized enterprise-level testing results in an integrated test suite that offers centralized execution and reporting.

Let us walk through the different ways in which DevOps makes use of test automation tools:

How DevOps Uses Test Automation to Speed Up Software Development and Delivery

DevOps testing lays its core focus on test automation within the application’s development pipeline to ensure that by the time the application is deployable, it is done without any further confusion. Some of the popular test automation tools of DevOps are Selenium and Water.

Here is a quick rundown on the popular DevOps tools:

1. New Relic– New Relic offers an end to end visibility along with improved customer experience and dynamic infrastructure. It also helps the DevOps team to save their time spent in monitoring applications.

2. Jenkins – Jenkins is a DevOps automation tool used for checking the execution of redundant tasks. Jenkins is an open-source CI/CD (Continuous Integration/ Continuous Delivery) server that allows users to automate various phases involved in the application delivery pipeline.

3. Splunk – This automation tool is used to access machine data. It offers operational effectiveness to both the development as well as the operations teams in DevOps. It offers enterprises the ability to be more productive, competitive, secure, and reliable.

4. Selenium – Being the most popular automation testing tool for DevOps, Selenium is designed to meet the specific needs of a wide range of different browsers. It makes use of lesser resources and supports parallel test execution which reduces the overall time required for the testing process. The test cases prepared can be run on any operating system as well.

Cucumber, Jasmine, JUnit, and JMeter are other popular test automation tools used by DevOps to accelerate application development and deployment.

Future of Test Automation in DevOps: Enhancing Application Development

With the evolution of continuous testing, DevOps has enhanced its test automation strategies where it is supported by practices such as a test-case design that is risk-based, stateful test data management, service virtualization, as well as seamless integration into the DevOps set of test automation tools.
