Checklist

This checklist provides a reminder of what we are going to look for when reviewing your PR. You need not complete this checklist prior to creating your PR (draft PRs are always welcome). If you are unsure about an item in the checklist, don't hesitate to ask. We're here to help!

• My PR is small in size (e.g. less than 1,000 lines of code, not including comments & specs/tests), or I have provided reasons as to why that's not possible.
• My PR passes TSLint validation using yarn run lint
• My PR includes TypeDoc comments for all new (or modified) public methods and classes. It also includes TypeDoc for large or complex private methods.
• My PR passes all specs/tests and includes new/updated specs for any bug fixes, improvements or new features. A few reminders about what constitutes good tests:
  • Include tests for different user types (if behavior differs), including: (1) Anonymous user, (2) Logged in user (non-admin), and (3) Administrator.
  • Include tests for error scenarios, e.g. when errors/warnings should appear (or buttons should be disabled).
  • For bug fixes, include a test that reproduces the bug and proves it is fixed. For clarity, it may be useful to provide the test in a separate commit from the bug fix.
• If my PR includes new, third-party dependencies (in package.json), I've made sure their licenses align with the DSpace BSD License based on the Licensing of Contributions documentation.
