There may also be fear and resentment around the idea of shifting left. Elevating shift left to a business-class requirement is essential. This is, of course, a false economy: We all know what the fallout can be from product failure, cyberattacks, and dissatisfied customers. If software development teams are incentivized purely by meeting deadlines, there is a risk that testing - and in its wake, bugs and security issues - becomes secondary. So why has shifting left not taken off as many people expected? Much of the challenge - as usual - comes down to corporate culture: It must start with leadership support. What goes wrong: Imposition, fear, and resentment So as code changes are checked in, the relevant security validations take place, and vulnerabilities are identified and fixed prior to release. Let’s look at security as an example: Shifting security practices left means that DevOps teams are embedding into their software iterations lifecycle the full scope of security from the requirement phase, audits, quality, checkpoints within each release, and remediation of defects. Shift left is a natural partner for continuous integration (CI) and the overall trend towards automation, which sits at the heart of DevOps. Pushing these activities left in the process also makes it easier to maintain them between future releases. It also supports the ethos of “fail fast, fix fast,” which helps remove code instabilities and improve quality.Īdditionally, shift left is a natural partner for continuous integration (CI) and the overall trend towards automation, which sits at the heart of DevOps and helps address the increasing complexity, scale, and speed of software releases. It is more cost-effective to reveal and fix defects and other issues earlier than later. It is not the answer to every software development challenge, but shifting left matters. Just 40 percent test upon each code change or at the start of a new software sprint, the survey states. The survey results show that only 19 percent use development teams for testing, as opposed to 81 percent that still depend on QA teams. Of companies surveyed, 63 percent responded that they’re starting to test only after a new build and code is being developed. The report, spearheaded by Gatepoint and Perfecto, surveyed executives from over 100 leading digital enterprises in the United States on their testing habits, tools, and challenges. Also, while the report focused on testing, anecdotally I hear from various companies that they have yet to embrace shift left in other areas, too. However, recent research carried out with the Gatepoint 2020 State of Test Automation Report shows us that shift left has not been widely adopted, at least not yet. I have talked about it frequently, and I believe it is fundamentally important to ensuring the quality of software, making it faster and better.Īreas that can be shifted left include functional and non-functional testing, code reviews, security code analysis (static and dynamic), security validations, performance and UX assessments, and code coverage assessments. Last year, “shift left” - the idea of automating and introducing a variety of activities earlier into the software build cycle - was one of the hottest topics in development.
