Modern C++ Programming with Test-Driven Development

(Note: CppUTest’s memory leak detector is not currently thread-safe. You will want to turn it off for this exercise ​only​; see ​http://www.cpputest.org/node/25​ for further information. Turning off memory leak detection will cause problems when coding the exercise in Chapter 8, ​Legacy Challenges​.)

We want ThreadPool to handle pulling and executing work on its own. We’ll need a thread. We create a test that shows how we want to send a Work object to the ThreadPool’s ​add​ function and let the pool execute the work asynchronously.

TEST(AThreadPool, PullsWorkInAThread) {
   pool.start();
   condition_variable wasExecuted;
   bool wasWorked{0};
   Work work{[&] {
      unique_lock<mutex> lock(m);
