Get to know the code

DevStack exercise

• Start DevStack in a VM on your laptop or in public cloud
• Validate the services are running
• Choose a service and issue an API call or use its client to verify functionality

LOG message exercise

• Add a few extra LOG.debug() lines to one of the methods of the API call you chose in the previous exercise
• Restart the corresponding service in your DevStack environment and find the new message in the logs
• Find out what parameters were passed to that method by using the LOG messages

Testing

• Test suites
  • Unit
  • Functional
  • Integration
• Testing framework
  • Tox

Testing exercise

• Run only one test class and not the whole suite
• Run one test case
• Group exercise
  • Ask a mentor to break the tested code of one test case
  • Find out what the modification is by running the test and analysing the test output

Test coverage exercise

• Find an open review which is less complex and download the patch
• Remove the code changes and run the tests
• Check whether the tests failed or not
• Explain what it means if they didn’t
• Comment on the open review
