Change is the only constant.
This applies to Software Testing more now than ever. Organizations are continually evolving and transforming by finding innovative ways to incorporate emerging technologies with a vision to ramp up quality.
While the Last gen used the Waterfall model, the current gen is using Agile model to enable faster delivery and quicker ROI. As part of this digital transformation, organizations — large and early-stage startups — are now moving towards DevOps and including CI-CD as a basic process to enhance its quality engineering efforts and enable early defect detection to reduce costs and time investments.
The software development teams now rapidly need to move towards Shift-left testing to fix the defects at a fast pace and increase feature velocity. Continuous Testing is another demand which needs to be involved as part of Shift-left testing to fix problems at an early stage and expedite feature velocity.
So what exactly is Shift-Left Testing?
Ten years ago, shift-left was a nouveau concept. It was originally introduced in 2001 by Larry Smith in his article in an effort to integrate the Quality Control(QC) and development parts of a software project. As the name implies, Shift-left testing is an approach to software testing and system testing in which testing is performed earlier in the life cycle (i.e. moved left on the project timeline).
Early testing helps to reduce the number of defects found. Prevention of defects escaping production) is better than a cure (defect fixes), especially when the cure is costly. You can extract maximum benefit out of this approach by using the two key DevOps practices: Continuous Deployment and Continuous Testing. Shift-Left is also about breaking down silos. It is a blessing in disguise as it gives an opportunity for bridging the gap between development and testing as it reduces the feedback time between the teams.
