To help answer questions about end-to-end tests, teams can collect and use test data by sending custom events to New Relic via its event API. By tracking code coverage, flakiness, and performance, teams can improve their testing strategies, empower data-driven decision-making, and enhance the overall quality of their software delivery lifecycle. With features like dashboards, NRQL queries, and observability practices, New Relic provides a platform for teams to visualize test metrics, identify potential gaps in code coverage, and make informed decisions about increasing investment in testing. By following best practices and avoiding common pitfalls, teams can create custom dashboards that foster empowerment and collaboration, ultimately leading to fewer incidents, reduced risk, faster lead times, and a possible reduction in the rate of change failures.
