There are two wheels in any software development organization: Development and Operations. They both go hand in hand and for the smooth running of both processes, it’s necessary that they run in complete sync and co-ordination. Now to ensure that there is no lingering between operation and software development processes like design, build, test, and deployment, all these teams have to be on the same page in terms of speed and integration. So all these development processes must attune.
Software testing, if not done efficiently, can be the biggest hindrance in the smooth running of any organization. For large and fast development operations and to make sure that the testing team does not lag behind it becomes imperative to implement Automation Testing.
So now let me get to the point and talk about how Automation Testing helps DevOps -
During the time when waterfall development processes were dominating all other development methods, all the different teams in an organization used to work independently. In waterfall technology, all the teams are laser-focused on their part.
- Planning team plans the line of action
- Defining team defines the various requirements and tools necessary to carry out that action
- Then Production team builds the product according to the specifications
- After building, the testing team performs the tests on the product to validate if it is meeting the requirements or not.
- Then finally the product is deployed in the market for service.
This creates a lot of problems between the teams when it comes to finding a solution to some bug introduced at a certain phase. And it is next to impossible to locate at what stage the bug was introduced. But ultimately the main problem was that release to market in this development cycle was extremely slow. In an era where competitors release new features every other month, this methodology fails to give an edge.
This is where Agile technology came into existence. Agile technology follows the process of continuous development, continuous integration, and continuous deployment. In this technology, the product goes through different build cycles. Each build cycle includes production, testing, and feedback. This accounts for the need of DevOps.
In DevOps, Development and Operations teams work together to achieve the target. Since the product is tested at every build cycle so the testing needs to be in pace with the development process to avoid any hassle between the teams. DevOps can not succeed if the tests are performed manually as they consume a lot of time. So, here automation testing plays a major role. Automating a testing process decreases the time required for testing an application and it provides support to the DevOps culture. Without automation testing, it becomes almost impossible to practice DevOps.
Automation testing is a Software testing technique to test and compare the actual outcome with the expected outcome. Today testing has become easier with the help of automated testing, allowing you to check for bugs in critical journeys on a wide variety of device types and OS in one go. Test Automation has advantages of the decreased cost of fixing bugs by 5X over the long term, run more tests with a minimal cost increase, increase the scope of coverage, and easier way to find defects.
Benefits of automation testing to the DevOps:
Environment Management Automating your tests can make your staff much more effective by reducing manual effort, making processes repeatable and stable. Complexity and differences between environments are mitigated as teams are able to build in configuration scripts instead of manually performing those same tasks.
Test Data Automation, particularly around DevOps, can be a great help in letting teams move past the drudge work of test data management. DevOps orchestration tools like Jenkins, Travis CI, Team City, etc. can be configured to handle extremely complex workflows around test execution.
Test Management Managing testing efforts can be made easier by automating your tests. You might find this blog useful.
