Testing

Unit Tests

The gtest framework library https://github.com/google/googletest is required in order to write and compile unit tests in libyami. To make it convenient to use, we add gtest source to subdirectory gtestsrc. The gtest documentation can be found in their source tree under docs (online or in the subdirectory gtestsrc).

To build gtest and enable the unit tests, when configuring libyami you need to specify:

--enable-tests

We highly recommend that unit tests accompany your contributed patches. See "Testing" section above. However, we do understand that not everything can be tested by a unit test. So use your best judgement to determine if a unit test is appropriate for your contribution. The maintainer(s) reserve the right to refuse submission's without unit tests, when reasonable, or if a submission causes existing unit tests to regress.
