DevOps |
There is an ever-growing demand for developing and delivering quality software products in less amount of time; To meet the market demands in less time, software development communities across the globe have come up with a software development strategy called DevOps.
DevOps stands for Development and Operations. This software strategy allows an all round partnering between the various teams involved in the development and delivery of a product. To brief, DevOps involves all the stakeholders of a software project starting from developers, product managers, quality assurance teams, operations, system administrators, security, and support teams. Implementing DevOps means you are pulling a plug to siloed teams and calling for a collaboration of teams involved in the software development life cycle(SDLC). However, to be able to get the full benefit of DevOps, testing has to be included in the continuous delivery chain.
When testing is included in DevOps it simply means the testing will take place in tandem with the development of the product. This fosters a faster feedback cycle which would enable the teams involved to stay in the know-about of how their tasks would impact the other delivery cycles. The positive outcome of testing is that product quality is checked throughout the DevOps.
If you have a dedicated DevOps team, it would be wise to go with automated testing rather than manual testing. Here are a few reasons.
The aim of DevOps projects is to automate as many manual processes and to make all the teams accountable for the delivery of the final product. An advantage of DevOps models is that there is continuous testing right from the commencement of the project and even after applications are in production and there is shared ownership of the end product. A DevOps testing strategy is said to be successful when you build, test, and release software faster and more frequently. To come up with an optimal DevOps testing strategy a detailed assessment of the software is required.
To gauge the maturity and quality of DevOps, you need to measure the KPIs continuously. This helps to identify defects by phase, stage, and functionality, and trace flaky test trends, and defects that escaped to production.
Not only web testing but also mobile testing strategies need to be put in place to build a successful DevOps testing strategy. DIY using Selenium Grid in-house, containerized computing, and cloud are the three ways to scale web testing, while Crowdsourcing, Cloud testing labs, and DIY are the ways to scale mobile testing. You also have the testing options for web and mobile across all browsers by using either Open Source Frameworks or to do codeless.
DevOps testing strategy is successful only if all the functional and non-functional tests, Key Performance Indicators (KPI), and code coverage are updated via Continuous Integration(CI). When CI is paired with automation, the teams will find it easy to test every new code that is iterated and make necessary changes without any time lag.
A stable test automation environment is required to ensure that continuous testing adds value to the test. When there is a change in the product code, the testing also changes. For this to happen seamlessly, the test automation suites should be reviewed, audited, refactored, and maintained every now and then.
The test report is generated after each testing activity. The developers would be able to quickly analyze, find the root cause of the failure, and take the required action if the reports are detailed.
Use Headless Browsers as a part of your DevOps testing strategy for testing web apps. This developer-friendly tool allows the developers to deliver a stable build to test. Headless Browsers such as Google Puppeteer and Selenium Grid are free. Google Chrome as well as Firefox support Headless Browser automation testing.
For a DevOps Testing strategy to succeed, involve the entire team including business testers, software developers, and so on in the test automation for each pull request and code change.
