Enterprises are leveraging DevOps to respond to changing market dynamics and customer needs. However, the biggest bottleneck to implementing a successful DevOps framework is its testing. Enterprises should adopt shift left DevOps testing principles and test automation enabling them to test faster and more comprehensively.
Too many companies utilizing DevOps frameworks still test their system manually, leading to a lack of visibility, duplication of efforts, and project backlogs. Resulting in the delay of the project and cost overruns.
Shift Left Testing Principles
Application testing performed at the end of the development cycle with a traditional framework can help. If applications don’t meet the quality standards of the individuals, don’t function properly, or fail to meet requirements, they are sent back to development teams. These are the optimal problem because bugs discovered late in the development stage are more complex, time-consuming, and expensive to resolve than those located earlier in the development process.
Shift Left refers to the software development process in which teams focus on seeking out and preventing problems instead of waiting for them to rear their ugly heads. Shift Left testing principles is mainly dependent on the testing process. This process is continuous throughout the software development life cycle, increases software quality, shortens prolonged test cycles, and reduces the possibility of unpleasant surprises at the end of the development cycle.
Why Choose Shift Left Testing Principles?
Cost alone is a strong incentive for shifting testing to the left. A bug caught in the testing phase before production can be a big problem. Then fixing it may cost 15 times more than it would in the design phase. Shift-left testing principles allow developers to discover bugs earlier to fix them before they reach the production environment.
In addition to cost savings, shift-left testing also saves time as the bugs are detected earlier.
How to use Shift Left?
Shift left requires two practices:
- Continuous testing: A process of testing applications early, often, and more comprehensively. Continuous testing isn’t feasible to perform manually. Quick feedback to development teams is offered concerning release candidates, enabling managers to make better-informed decisions to optimize the value of a release.
- Continuous deployment: Continuous deployment automates the provisioning and deployment of new builds, which enables continuous testing to happen efficiently.
Thus, test automation is integral to continuous testing. However, incorporating test automation has its challenges discussed below.
Challenges for shift-left DevOps
- Time is taken for building: Many enterprises consider building their test automation frameworks, but this rarely works well because it’s time-consuming and costly to build it from scratch.
- The steepness of the Learning Curve: Enterprises that use code-based open-source tools like Selenium rely on technically trained employees for maintaining the test automation framework.
- Maintenance Cost is high: Most test automation tools use static scripts which means that they cannot automatically adapt to changes that occur from UI changes in the form of new screens, buttons, user flows, or user inputs.
Overall, DevOps provide better insight for catching bugs or the better running of the device before any projects. It is always better for people to opt for DevOps.
