Logs should be included.* *For example, when changing something in the core OS functions, you may want to run the OSTest application to verify that there are no regressions. Changes to ADC code may warrant running the `adc` example. Adding a new uORB driver may require that you run `uorb_listener` to verify correct operation.* *Pure documentation changes can just be tested with `make html` (see docs) and verification of the correct format in your browser.* **_PRs without testing information will not be accepted.
