Integrating testing activities earlier in the development cycle can catch defects faster, improve code quality, and deploy software more quickly, saving resources and reducing downstream problems. Shift-left testing involves moving testing earlier, while early quality assurance extends this approach by incorporating quality checks throughout development, requiring skills in testing fundamentals, automated testing tools, CI/CD pipelines, and code review best practices.
Shift-left testing revolutionizes the development cycle by integrating testing into every stage, reducing defect density, improving collaboration, and accelerating time-to-market through test-driven development, behavior-driven development, continuous integration and deployment, and infrastructure as code.
