Shift-left continuous testing is a practice that combines the concepts of shift-left testing and continuous testing to automate as much application testing as possible, maximize test coverage, and perform testing early in the development pipeline. By shifting testing left, organizations can catch bugs earlier, lower business risk, and increase confidence in the quality of their release candidates. This approach involves automating testing for each feature as it is developed, integrating automated test scripts with CI builds, and making "has automated testing" part of acceptance criteria for user stories. By adopting shift-left continuous testing, organizations can save time and heartache by decreasing the time and effort required to fix issues and increasing the quality of their products.
