Shifting your testing either left or right can meet different needs and improve different aspects. How do you know whether to make a change? Let your test cycles be your guide. Just like when driving a car with a manual transmission, if the engine starts to whine or you’re afraid you’re about to stall out, switching gears may be just what you need.
The earlier you find out about problems in your code, the less impact they have and the less it costs to remediate them. Therefore, it's helpful to move testing activities earlier in the software development lifecycle—shifting it left in the process timeline. This article explores the shift-left methodology and how you can approach shifting left in your organization.
“Shift left” is one of the latest buzz terms in software testing. Movements like agile and DevOps recommend that testers shift left, but what does that mean, exactly? Here's how one tester became a believer in the shift-left movement; how he got his team's developers, analysts, designers, and managers on board; and how his entire organization has benefited from the shift.
There is a lot of talk in the testing world about shifting left. Basically, “shift left” refers to moving the test process to an earlier point in the development process, independent of the development approach. This article explores a case in which shift-left has been applied, and the lesson is that shifting left cannot be achieved by testers alone—it must result from a team effort.
Shifting left has been focused on testing proprietary code earlier. But at what point in the lifecycle are you checking your open source compliance and ensuring you do not have security vulnerabilities? If you shift this process left and perform it earlier in your software development lifecycle, just like with testing, you can see the same benefits of saving time, money, and headaches.
