To avoid long wait times, you run only a few very fast tests. This is tolerable when you are working on isolated code and using unit tests, but as soon as integration of the new code with the old code comes into play, it becomes a problem. 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. 24 24 25 25 **Asynchronous Testing** 26 26
