How to use gtest in ardupilot ?

Hi, several days ago,
i watched a commit from peterbarker , which add gtests for snprintf : https://github.com/ArduPilot/ardupilot/commit/412bf24b9a6fb69a914510dc58a1f9b242628615

Here is my questions:

How to run gtest in ardupilot in sitl build ?
Where to get the gtest result?

Can someone tell me how, thanks a lot.

OK, so I broke this the other day with a commit which added a compiler
sanity check which the gtest suite fails. I’ll be patching that in the
next day or so.

In the meantime, the addition step you need to take is to comment out the
addition of -Werror=suggest-overrides in Tools/ardupilotwaf/boards.py

Past that, this is how you run the gtests:

./waf configure --board=linux
./waf tests
ls ./build/linux/tests/

More tests are always welcome :slight_smile:

Hi peterbarker, i follow your guide and it work perfectly, thanks a lot.

Just to complement: you can use waf to run the tests: ./waf check (which runs all tests that haven’t run or have failed before) or ./waf check-all (which always runs all tests).
