Summary
This is the last chapter of this book and it explained one of the most confusing and difficult aspects of writing software: how to test multiple threads. You’ll find a lot of books that explain multi-threading but fewer will give you advice and show you effective ways to test multiple threads.
Because the target customer of this book is a microservices C++ developer who wants to learn how to use TDD to design better software, this chapter tied everything in this book together to explain how to test multi-threaded services.
First, you learned how to use multiple threads in your tests. You need to make sure you handle exceptions inside tests that start additional threads. Exceptions are important because the testing library uses exceptions to handle failed confirmations. You also learned how to use a special helper class to report failed confirmations that arise in additional threads.
Threads must also be considered when writing and using libraries. You saw how...
