__Note:__ When running your tests with multi-configuration generators like
Visual Studio, you might get errors "Test not available without configuration."
You then have to pick one configuration (e.g. ` -C Debug`) in the `ctest` call.
If you added new tests, approval tests are very likely to fail. If they
do not, it means that your changes weren't run as part of them. This
_might_ be intentional, but usually is not.
