Add delay to gtest Test Case

Question

I'm using google test framework for testing hardware Ethernet switch. Some operations (e.x. enabling RSTP) take time to proceed. So I need to implement some sort of a Sleep() function inside the test case:

TEST_F(RSTP, enableRSTP) {
    snmp.set(OID, Integer32(3));
    // after changing value switch is unavailable
    // so I need to wait before request
    auto result = snmp.get(OID);
    auto res = std::get<Integer32>(result);
    ASSERT_EQ(res, Integer32(3));
}

How do I accomplish this?

As mentioned in one of the comments, you could just use (c++14):

#include <chrono>
#include <thread>
TEST_F(RSTP, enableRSTP) {
  ...
  using namespace std::chrono_literals;
  std::this_thread::sleep_for(2s);
  ...
}

... or for c++11, replace 2s with:

std::chrono::seconds(2)

If you don't use >= c++11, then this becomes an OS specific question (not standard c++)
