How to add timeout to test when using Google Testing framework

Question

I'm in need to test C++ code - and I've decided to use Google's testing framework. I need to make sure that a test doesn't hang due to a new bug. In the .NET testing framework it's possible to add [Timeout] on to of the test in order to make sure that it does not run for too long.

How can I create a simialr behavior when using Google Test?

Answer 1

Google test does not offer something similar. http://code.google.com/p/googletest/issues/detail?id=348

You would have to add this functionality in C++

re "you would have to [implement] this functionality in C++" here is an example implementation: #25852889 (the two questions should probably be merged somehow) – Minard

Answer 2

You can try to set test properties through cmake: https://cmake.org/cmake/help/v3.8/prop_test/TIMEOUT.html

example:

set_tests_properties(${Tests} PROPERTIES TIMEOUT 10)

Problem with this approach is that within CI, if you rely on getting report files (json or xml) - and using ctest's timeout: no result file is written .. – Vostok

Answer 3

Building on what @ymochurad said, we ended up using the ctest cli optional argument:

ctest --timeout 1

to set the a default timeout for all tests. This was sufficient for our needs - hopefully it will help others.
