The robert will move around a room, avoiding obstacles using the Forwards Ultrasonic Sensor, as per the following state machine diagram:
The unit tests are controlled by the constant RUN_UNIT_TESTS which in turn applies conditional compilation using the preprocessing directives #ifdef #ifndef and #endif. You either run the unit tests using #define RUN_UNIT_TESTS or you run the robot program. You can not run both at the same time. This is because the unit tests start to run after the first call to moveRobot() resulting in the failure of the first assertion in test(ReadyToPingForward).
Another issue with the unit tests is that you cannot predict the order that the tests will run. For this reason, there are a number of assertions in test(ReadyToPingForward) to ensure the assertions are run in the correct order.
Ensure you understand the github workflow: https://guides.github.com/introduction/flow/index.html
Please keep pull requests focused on one thing only, since this makes it easier to merge and test in a timely manner.
If you need help with pull requests there are guides on github here:
https://help.github.com/articles/creating-a-pull-request/
The main flow for a contributing is as follows:
- Login to github, go to the github_exercise_student repository and press
fork. - Then using the command line/terminal on your computer:
git clone <url to YOUR fork> cd github_exercise_studentgit checkout mastergit checkout -b my-new-code- Make changes
git add <files that have changed>git commit -m "<short description of change>"git push origin my-new-code- Create pull request using github UI to merge your changes from your new branch into
github_exercise_student/master - Repeat from step 4 for other new changes.
The primary thing to remember is that separate pull requests should be created for separate branches. Never create a pull request from your master branch.
Later, you can get the changes from the github_exercise_student repo into your local master branch by adding github_exercise_student as a git remote and merging from it as follows:
git remote add <https URL to github_exercise_student/github_exercise_student.git>git checkout mastergit fetch github_exercise_studentgit merge github_exercise_student/mastergit push origin masteris an optional step that will update your fork on github
