zhangxinyao88 opened a new pull request, #58682: URL: https://github.com/apache/spark/pull/58682
### What changes were proposed in this pull request? Extend the existing [SPARK-59273](https://issues.apache.org/jira/browse/SPARK-59273) CHAR/VARCHAR `na.fill("x")` test with an integer column. The test verifies that string fill values still fill CHAR and VARCHAR columns, while a non-string column is left unchanged. ### Why are the changes needed? SPARK-59273 broadened string matching to include the CHAR/VARCHAR family. The follow-up fix in #58646 restored skipping non-string columns. The existing tests cover those behaviors separately. This test covers the mixed-schema case directly, so a future change cannot reintroduce the interaction that caused the regression. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The targeted test was started locally, but its first-run SQL test compilation was interrupted before execution completed. GitHub Actions will run the full suite. ### Was this patch authored or co-authored using generative AI tooling?
