Instructions

clone the repo

1. Copy your repository url to the clipboard.
2. Open intellij and select checkout from version control.
3. Select the git option and paste the url.
4. Configure your project directory and name.

setup tests

Open the terminal from intellij and run the following command.

./setup.sh

project layout

Your project should have two folders with the following content.

.
├── src
│   └── Hello.java
└── tests
    ├── HelloTest.java
    └── TestRunner.java

write the code

Complete the hello method in src/Hello.java so that it prints out a message multiple times. The message and count are parameters to the method.

test the code

The main method invokes the hello method with given parameters. When you compile and run the Hello class, the main method executes. The following shows an example method call with its expected output.

invocation

hello("some message", 2);

output

some message
some message

Run the HelloTest class in tests/HelloTest.java to make sure your code is correct. You can also run TestRunner to estimate the grade for your project.

push the code

Remember to push you code to GitHub!

git add .
git commit -m "your commit message"
git push

double check

The tests may update when you push or pull your project. After pushing your code run the following command.

git status

If you see that tests has been modified, then rerun your tests to make sure they all pass, and then update your project again.

Notes

The tests directory actually references another repository. When you cloned the repo the directory was actually empty. The setup script downloaded the appropriate files and installed hooks to keep them up to date. Whenever the project is updated with git pull or git push the tests directory will also update.

Without the setup script you could do the following:

# after cloning the repo
git submodule init
git submodule update --remote

# checking for updates
git submodule update --remote
git status
# if status shows modified tests
git commit -am "updating tests"
