23		-A simple TDD workflow is to write new code, run tests locally, wait for them to finish, and if they pass, move on. To avoid long wait times, you run only a few very fast tests. This is fine when you are working on isolated code that is checked by unit tests, but as soon as integration of the new code with the old code comes into play, it becomes a problem. Now you have two bad choices: either you run a few fast tests and do not use the full power of your test suite, resulting in low coverage and possibly missing bugs that would have been easier to fix if they had been caught earlier, or you run all the tests locally and are unproductive for a long time while waiting for them to finish. This problem can be solved with asynchronous testing.

27		-When you push code into the code repository, there should be a DevOps infrastructure that triggers a CI pipeline that runs all the tests. This allows your code to be extensively tested while you continue to work without waiting. If the CI pipeline succeeds, the test suite has proven that your code is okay. If the CI pipeline fails, you should receive a notification, such as an SMS, an email chat that triggers a ringtone, or a desktop notification, so that you can immediately stop what you are doing and fix the problem. Push the fix again and continue working without waiting for the tests to finish.

29		-It is not uncommon to have many CI pipelines running simultaneously for the same developer. While this may require advanced DevOps infrastructure, it's often worth the investment. Or you can simply use cloud providers that do this automatically in the background.
	27	+You should have DevOps infrastructure which when pushing code to the code repository triggers a CI pipeline executing all tests. Doing that enables you to directly go on working without the need to wait minutes for the tests to finish. If the CI pipeline succeeds, In case the CI pipeline fails, you should get a notification to fix the CI pipeline immediately. This enables quite comprehensive testing, even having the same testing jobs running in parallel, even long taking ones.
