Answer 1

So I liked these solutions, but thought it might be easier with a promise, I had to wait for my test to startup:

std::promise started;
EXPECT_CALL(mock, start_test())
    .Times(1)
    .WillOnce(testing::Invoke([&started]() {
        started.set_value();
    }));
system_->start();
EXPECT_EQ(std::future_status::ready, started.get_future().wait_for(std::chrono::seconds(3)));
