Jul 1, 20252025-07 Monthly Summary for govuk-one-login/performance-testing: Delivered a new performance testing profile perf006Iteration5SpikeTest to strengthen spike-load testing, integrating a new createI3SpikeSignUpScenario-based configuration with defined authentication, duration, and user-count parameters into the performance framework. This expands testing coverage for peak conditions and supports earlier identification of performance regressions in signup/auth paths. No major bugs fixed in this period for the repo.
