> 1) It’s now possible to run a wide range of tests on an application very quickly through its public interface, enabling a broader scope of testing without excessive time or resource constraints.

> 2) Improved test frameworks have brought down the cost and effort required to write robust, maintainable integration tests, offering accessible, scalable ways of validating the interplay between components.

> 3) The development of sophisticated debugging tools and enhanced observability platforms has made it much easier to identify the root causes of failures. This improvement reduces the reliance on narrowly focused unit tests.

Citation needed on all of these. Where are the specific tools that make running all of these magically fast and reliable (read: not flakey) integration tests possible?
