Shift-Left testing

Shift-left testing emphasises the early introduction of testing activities in the software development lifecycle (SDLC). Using this approach, you aim to detect and prevent defects earlier, reducing the cost and time associated with software testing. That is why testing activities like system testing and user acceptance testing; which traditionally occur later in the SDLC, are moved earlier. Traditionally, testing has been performed in the later development stages after completing coding. However, that often means identifying defects late in the development cycle, which can be costly and time-consuming. There are several key reasons why shift-left testing has become one of the software testing trends:

1. Early bug detection: By conducting testing activities earlier in the SDLC, defects can be identified and addressed early. This way, you prevent the major issues from surfacing later in development when they become up to 40x more expensive and time-consuming to fix.
2. Faster feedback loop: Shift-left testing enables faster feedback on the software quality. This way, developers can quickly identify and resolve issues, shortening the development cycles and leading to faster time to market.
3. Cost and time savings: If you detect and address defects earlier, you reduce the overall cost and time dedicated to testing and fixing the bugs. Fixing issues early is generally less expensive and time-consuming than fixing them later.
4. Continuous Integration and Continuous Delivery (CI/CD): Shift-left testing aligns well with the CI/CD principles, where you develop the software in small, frequent increments. Integrating testing early into the CI/CD pipeline allows you to test the software continuously, ensuring higher quality throughout development.
