PR Requirements

Developers, verify you have completed the following items by checking them off:

Style

Review the style guide

• For dependencies, pin OS package and Python package versions
• For security, set least privileged account with USER nobody in the Dockerfile when possible
• For size, use the slim SDK images when possible: komand/python-3-37-slim-plugin and komand/python-3-37-plugin
• For error handling, use of PluginException and ConnectionTestException
• For logging, use self.logger
• For docs, use changelog style
• For docs, validate markdown with make validate which calls mdl to lint help.md

Functional Checklist

• Work fully completed
• Functional
  • Any new actions/triggers include JSON test files in the tests/ directory created with icon-plugin run -c sample $action > tests/$action.json
  • Tests should all pass unless it's a negative test. Negative tests have a naming convention of tests/$action_bad.json
  • Unsuccessful tests should fail by raising an exception causing the plugin to die and an object should be returned on successful test
  • Add functioning test results to PR, sanitize any output if necessary
    • Single action/trigger icon-plugin run -T tests/example.json --debug --jq
    • All actions/triggers shortcut icon-plugin run -T all --debug --jq (use PR format at end)
  • Add functioning run results to PR, sanitize any output if necessary
    • Single action/trigger icon-plugin run -R tests/example.json --debug --jq
    • All actions/triggers shortcut icon-plugin run -R all --debug --jq (use PR format at end)

You must validate your work to reviewers:

1. Run make validate and make sure everything passes

3. Copy (icon-plugin ... | pbcopy) and paste the output in a new post on this PR.
4. Add UI screenshot of the workflow used for testing
5. Add UI screenshot of the job output used for testing
6. Add UI screenshot of the artifact (See rules in UI Checklist) used for testing
