The Shift Left testing approach is not a new term. Across the globe, more and more organizations are shifting left for various reasons. It’s also regarded as a culture as it allows businesses to instil collaborative work efforts and launch products into the market faster.

This testing approach expedites testing and helps detect bugs in the early stages of development. For teams with a heavy focus on faster time to market and continuous integrations — Shift Left is the way forward.

But, First, What’s Shift Left Testing?

Shift Left is a testing approach where testing begins right from the software development phase. Testers work in tandem with developers and product managers in this testing process to focus on the overall efficiency of the product.

Since the team works towards a common goal, Shift Left allows teams to shift the testing process left during a project timeline and test whenever required to detect and deal with any concerns or bugs in the early phases. With this, you are not just cutting down risks but also time and costs.

Besides, with the growth of CI and CD, it makes more sense to test out the features or any aspects of the software rather than waiting for the final stages.

Benefits of Shift Left

  • Faster time to market as testing happens from the development phase itself.
  • Increased test efficiency.
  • Low-cost affair as you can detect and fix bugs in the initial stages.
  • It facilitates developers and testers to come together and work as a team; testers don’t have to work in isolation any longer.
  • You’ll have more control over your project schedule and delivery timelines, as Shift Left also enables transparency.
