Shift-left testing movement (2010s)
Software teams began moving quality checks earlier in the development cycle, integrating unit tests, static analysis, and linting into the commit and build pipeline rather than relying on post-release QA. Tools like SonarQube and ESLint became standard parts of CI/CD.
Bugs and security issues were caught before reaching production, cutting remediation costs.
Continuous integration and automated code review became industry norms across software development.
Code Agent applies the same shift-left logic to accessibility, treating WCAG compliance as a code-quality gate rather than a post-launch audit.
