Speeding Up Python Tests Using Asynchrony. The Entire Test Run in the Execution Time of a Single Test

Executing tests related to external systems can take several minutes, and sometimes even more! What should we do if we have not just a couple of such tests, but dozens or hundreds of them? One of the solutions is to switch to using asynchronous API and asynchronous tests, with the help of which we can remove the limits of test execution duration without increasing the duration of test runs themselves.
