21 21  **Synchronous Testing**
22 22  
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 which 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 only a few fast tests and do not use the full power of your test suite, possibly missing bugs that would be easier to fix if they were 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 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, the comprehensive test suite proofed your code to be fine. If the CI pipeline fails, you should get a notification like an SMS or Email, abort your current work immediately to fix the problem. Push the fix again and continue working without waiting for any tests to finish.
