Brain made of computer circuits and binary code A Simpler Way of Using Machine Learning to Shift Testing Left

The advantages of shifting left and testing as early as possible are obvious. But as you automate more testing, the test suite grows larger and larger, and it takes longer and longer to run. Instead, just automate the process of finding the right set of tests to run. The key to that is machine learning. This isn't AI bots finding bugs autonomously without creating tests; this is a different way to use machine learning, and it’s far simpler.

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.

Graph showing how testing earlier costs less and means fewer overall defects The Shift-Left Approach to Software Testing

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.
