The shift-left testing strategy

Testing earlier and often is the idea behind shift-left testing. By moving testing to earlier in the development life cycle, we will prevent errors from being found later in the process or, worse yet, after deployment into production. Shift-left testing moves testing into the development and build phase, which allows the team to detect defects and bugs early on. This allows the team to address and fix these issues faster and before they can do any real damage.

The shift-left testing approach to software testing greatly enhances the deployment and release process, allowing for faster releases that can occur daily, weekly, or even hourly in some cases.

The lack of testing or not implementing testing properly can lead to defects and bugs being deployed into production, which leads to expensive bug fixes and delays in the releasing of new features.
