[v3,11/17] test: libipa: Add Vector class test

21971 diff mbox series

Add a unit test to exercize the API of the ipa::Vector class.

The test binary being called 'vector', implicit includes cause the
binary to be picked by '#include <vector>', causing builds to fail. Set
implicit_include_directories to false to avoid this, as done in commit
6cd849125888 ("test: Don't add current build directory to include
path").

Changes since v2:

- Fix initialization of 'v1' variable

Hi Laurent,

thank you, it works for me now.
