Exercises

You've learned a lot about how to configure the Continuous Integration process. Since practice makes perfect, I recommend doing the following exercises:

1. Create a Python program that multiplies two numbers passed as the command-line parameters. Add unit tests and publish the project on GitHub:
   1. Create two files: calculator.py and test_calculator.py
   2. You can use the unittest library at https://docs.python.org/library/unittest.html
   3. Run the program and the unit test

2. Build the Continuous Integration pipeline for the Python calculator project:
   1. Use Jenkinsfile to specify the pipeline
   2. Configure the trigger so that the pipeline runs automatically in case of any commit to the repository
   3. The pipeline doesn't need the Compile step since Python is an interpretable language
   4. Run the pipeline and observe the results
   5. Try to commit the code that breaks each stage of the...
