The File we are running contains two functions, factorial and check_leap_year.

In this discussion section you will need to design test cases to test whether the code in these functions is correct.

The following section provides the syntax for invoking the methods, and English descriptions of what each function is supposed to do.

You should plan and then write tests in your groups for these methods. Then we'll test our code and see if it works!

For example:
factorial(0) should return 1
factorial(1) should return 1
factorial(-5) should return None
factorial(5) should return 120

For example:
check_leap_year(1900) should return False
check_leap_year(1912) should return True
check_leap_year(2000) should return True

1. Fork the DS4 repository here - https://github.com/yjlintw/si206-ds4.

2. Clone the DS4 repository that you just forked. Do not clone this one, you won't have the permission to push to this repo. git clone <remote repo URL>

3. Check status continuously to keep track of changes in your code and directory git status

4. After writing each test, add your modified code to the local repo git add <filename>

5. Commit the changes in code to the local repo git commit -m <commit message>

6. After each commit, check the history of your commits git log

7. Once all test cases are done, push your code to github to the repo you had forked from DS4. (Use the same URL you had used for cloning)

git remote add origin <remote repository URL> git remote -v git push -u origin master
