Automated Regression Testing & DevOps Go Hand in Hand

regression_testingDevOps has been described as a “paradigm shift in the way technology companies look at the marriage between software development and the infrastructure that powers it.”  DevOps emerged as an offshoot of Agile development practices, which allow for quicker deployment of new software releases by tightening the relationship between developers and business stakeholders.  DevOps is simply a philosophy and practice of uniting IT operations and developers to create an infinite loop of new releases and immediate monitoring and feedback.

DevOps generally starts with adopting an automation platform that is to be used for coding all systems-related configuration and for deployment of new releases.  Gone are the days of manually configuring servers when deploying applications across multiple servers and environments.  The automated configurations are deployed either in non-virtualised data centers or, ideally, in the Cloud. As software development takes place, it will move into quality assurance and then to the production environment.  Instead of the software being deployed across multiple manually-configured servers, with all of the deployment complexities this could cause, the automation platform allows for rapid deployment into production.

This means updates can be released more often and the data centre automation platforms make the process quick and simple.

Automated Regression Testing is the Key to Success

DevOps supports faster deployment and release cycles.  Automated regression testing is a key part of ensuring the quality of each release..  Automated regression testing practices are common in traditional software development environments, but are even more critical in DevOps because of the continuous releases of working software.

With DevOps, the building and deployment of a software application / website is supported at every step of the way via test automation.  The automated tests can be integrated directly into the continuous-integration workflow, mapped to each component and overall, each release as a whole

Testing as soon as coding is complete and updates are ready results in catching bugs right away.  When you test during implementation, you won’t have to worry about refactoring down the line or about having to go back and undo mistakes that were made weeks ago.  You can skip manual regression tests, which waste time and which could potentially need to be repeated multiple times if the code is changed during the test cycle.  Since your software can be tested immediately whenever a commit is made, problems can be diagnosed as soon as they are introduced.

DevOps makes multiple rapid code pushes possible, whether you are pushing out new code hourly, daily or weekly.  With automated regression testing, all of this new code can be tested right away no matter how frequent the release cycle.

Getting Started with Automated Regression Testing

Automated testing is the only realistic way to support rapid, stable releases.  It is important to integrate automated regression testing as you start with DevOps.  e-testing can provide automated testing services and assist you in creating a full library of automated tests for incorporating into your workflow.

DevOps can be an effective method of development for companies of any size and should ideally be adopted at the beginning of a project. Speak with one of e-testing’s Principal testing consultants as soon as possible to get started on developing your automated testing process to make DevOps a success.
