2.15 Audit and test for bugs or issues requiring resolution

https://w3c.github.io/sustainableweb-wsg/#audit-and-test-for-bugs-or-issues-requiring-resolution

Regularly audit for issues or problems, running tests at regular intervals in both simulated and real-world scenarios to ensure stability of the project.

Success Criterion: Ongoing evaluation

Evaluate current user experience and check the codebase for bugs, identify performance issues, and account for accessibility, sustainability, or security problems at appropriate regular intervals, such as every month or quarter.

Success Criterion: Automated tests

Maintain an automated test suite that covers critical functionality and run it consistently during builds and releases to catch regressions early.

Success Criterion: Performance testing

Identify and resolve bottlenecks or issues in the underlying code or infrastructure which could impact sustainability and performance to encourage a smooth, frictionless user journey. Account for both simulated and real-world metrics. Monitor performance across every release cycle using appropriate tooling or through research and auditing.
