Why Is Shift-Left Testing Gaining Popularity in Agile Development?
In the Agile world where development activities are released often and multiple rounds of development are accomplished in a limited timeframe, the quality of software cannot be an add-on. Earlier, software testing techniques that were practiced were a phase-based testing cycle and were proven costly and inadequate for Agile due to its continuous integration and delivery systems. This has created shift-left testing culture that seeks to ensure that testing is done beginning from the early stages of development. Application of shift-left testing practices is common in Agile setting given that it holds that early testing is critical to the achievement of efficiency, low cost, and integrated effort. It has become popular with Agile teams and QA & software testing professionals as a way towards responding to time-to-market considerations for today’s development iterations. Can we, therefore, look at shift left testing in detail on why it is used and how it integrates with the Agile d
