Steps to create a pull request

These are the recommended steps to create a pull request:

  1. Create a forked repository of
  2. Clone the forked repository into your local environment
  3. Add a git remote to upstream for local repository with command git remote add upstream
  4. Make code changes and add test cases, refer Test specification section for more details about test
  5. Test the changed codes with one-click build and test script
  6. Commit changed code to local repository with clear message
  7. Rebase the code to upstream via command git pull --rebase upstream master and resolve conflicts if there is any then continue rebase via command git pull --rebase continue
  8. Push local commit to the forked repository
  9. Create pull request from forked repository Web console via comparing with upstream.
  10. Complete a Contributor License Agreement (CLA), refer below section for more details.
  11. Pull request will be reviewed by Microsoft OData team
  12. Address comments and revise code if necessary
  13. Commit the changes to local repository or amend existing commit via command git commit --amend
  14. Rebase the code with upstream again via command git pull --rebase upstream master and resolve conflicts if there is any then continue rebase via command git pull --rebase continue
  15. Test the changed codes with one-click build and test script again
  16. Push changes to the forked repository and use --force option if existing commit is amended
  17. Microsoft OData team will merge the pull request into upstream

Test specification

All tests need to be written with xUnit. Here are some rules to follow when you are organizing the test code:

  • Project name correspondence (X -> X.Tests). For instance, all the test code of the Microsoft.Restier.Core project should be placed in the Microsoft.Restier.Core.Tests project. Path and file name correspondence. (X/Y/Z/A.cs -> X.Tests/Y/Z/ATests.cs). For example, the test code of the ConventionBasedApiModelBuilder class (in the Microsoft.Restier.Core/Convention/ConventionBasedApiModelBuilder.cs file) should be placed in the Microsoft.Restier.Core.Tests/Convention/ConventionBasedApiModelBuilderTests.cs file.
  • Namespace correspondence (X.Tests/Y/Z -> X.Tests.Y.Z). The namespace of the file should strictly follow the path. For example, the namespace of the ConventionBasedApiModelBuilderTests.cs file should be Microsoft.Restier.Core.Tests.Convention.
  • Utility classes. The file for a utility class can be placed at the same level of its user or a shared level that is visible to all its users. But the file name must NOT be ended with Tests to avoid any confusion.
  • Integration and scenario tests. Those tests usually involve multiple modules and have some specific scenarios. They should be placed separately in X.Tests/IntegrationTests and X.Tests/ScenarioTests. There is no hard requirement of the folder structure for those tests. But they should be organized logically and systematically as possible.
