### Rationale for this change Two TODOs in `test-dplyr-join.R` (lines 191-192) requested test coverage for edge cases in join operations. These TODOs were added in commit c273ea72. ### What changes are included in this PR? Added two test cases to `r/tests/testthat/test-dplyr-join.R`: Both tests use `compare_dplyr_binding()` to ensure Arrow's join implementation matches dplyr's behavior. ### Are these changes tested? Yes, these are the tests. They verify Arrow's join implementation against dplyr's reference behavior for these edge cases. ### Are there any user-facing changes? No. This only adds test coverage. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
