Adopting Shift-left Testing for Early Defect Detection in SDLC
If you’re planning to work in software testing and bring serious value to an Agile or DevOps team, there’s one approach you need to know: Shift-left testing. In simplest terms, shift-left testing means starting testing activities earlier in the Software Development Life Cycle (SDLC). Instead of waiting until the end of development to find bugs, you start testing during the planning, design, and coding phases. That way, defects get caught when they’re still cheaper and easier to fix. It also means that testers are involved from day one, helping shape test strategy alongside product design. The types of shift-left testing you should know. · Unit testing tests individual code units in isolation. This is often done by developers using Test-Driven Development (TDD). · Integration testing ensures that components work together as expect...
