SOFTWARE ENGINEERING

Detailed explanation-1: -The “shift left” testing movement is about pushing testing toward the early stages of software development. By testing early and often, a project can reduce the number of bugs and increase the quality of the code. The goal is to not find any critical bugs during the deployment phase that require code patching.

Detailed explanation-2: -The traditional shift left testing process moves the testing lower down, hence, towards the left on the right side of the V Model. The traditional shift left testing process focuses more on Unit Testing and Integration Testing.

Detailed explanation-3: -Shift-left testing is a part of continuous testing, as it employs the same process of testing at every stage and as often as possible. While continuous testing is part of the process of executing tests in the DevOps pipeline to get feedback on bugs as soon as possible, shift-left testing focuses on defined objectives.

Detailed explanation-4: -Step 1-Implement security policies. Security policies are a good first step for shift left testing. Step 2-Implement testing early in the SDLC. Step 3-Embrace security automation.
