The early tests of the developers' development cycle can easily catch problems that must be addressed before they reach the production environment. By discovering these issues earlier, developers need not waste time applying workarounds to flawed implementations. But the question arises, why does DevOps recommend shift left testing principles? The answer to this question is mentioned in the following part of the post.
The recent practice these years has been the shift left security testing. Following this application testing in the development cycle security testing has become more crucial. At this point, various kinds of analysis and security teams will now organize the security testing.
The benefits of DevOps shift-left:
The shift left testing's most crucial task is to reduce the overall development time of the software.
- Speed of delivery is increased:
It’s not rocket science that the sooner someone starts, the sooner they finish. Identifying critical bugs early in the Software Development Cycle allows one to fix the problems much sooner and more efficiently. The result is a significant decrease in the expanse of time between releases and a faster delivery time.
- Test coverage improved:
The evaluations are made quickly if the test starts with an execution right at the start of the development process. All features, functionalities, and performance of the software can be easily evaluated within less time. Test coverage percentages increase when shift-left testing was introduced. The overall quality of the software significantly enhances by increased test coverage.
- Workflow is efficient:
The shifting left DevOps is worth the effort and time it takes for its implementation. The shifting left DevOps allows the required team to go deeper into the product and implement their innovative testing solutions. Furthermore, it also allows the testing team to become more comfortable with the tools and techniques involved in this process. In addition, the simplification of several aspects of software development is done by shifting left testing DevOps.
- Low testing cost with lower development:
Debugging is one of the most strenuous aspects of software development. Usually, the progress of the software increases the cost of fixing a bug significantly. The earlier one finds their bugs, the easier and quickly one can fix them. Let us take an example: A payment app discovers a security vulnerability only after the release of its latest app version. Now, this would have cost some more if the team had found the vulnerability earlier during the time of its development. Since the company was unable to do so, it will now have to spend significantly more time, effort, and money to fix this problem. The implementation of change is always complex in a production environment making it difficult to do anything after the fact, not to mention the associated total cost of late maintenance.
- Product quality becomes better:
The Shift Left testing approach positively impacts code quality with rigorous and frequent code quality checks. It facilitates timely correspondence between stakeholders, developers, and testers to ensure timely feedback, which helps improve code quality. It means that the customers receive a stable and high-quality end product.
