zhangxinyao88 opened a new pull request, #3859: URL: https://github.com/apache/parquet-java/pull/3859
### Rationale for this change Continue #3289 with argument-to-behavior coverage for `footer`, `pages`, and `dictionary`. Existing footer and dictionary tests set command fields directly; the page-size tests also bypass CLI argument parsing. The `head`, `cat`, and `scan` coverage in #3858 is separate. ### What changes are included in this PR? Add seven cases using the existing CLI helper and a deterministic two-column Parquet file: - `footer` emits interpreted metadata by default and raw Thrift metadata with `--raw`, with schema and row-count assertions on parsed JSON. - `pages` lists both columns by default, honors `--columns`, and combines column selection with `--raw` page headers. - `dictionary --column` emits the selected column's decoded values, checking both columns with distinct expected contents. The fixture is checked for dictionary-encoded pages. Assertions avoid complete formatted-output snapshots and dictionary ID ordering. Existing page-size tests remain intact. ### Are these changes tested? `./mvnw -o -B -ntp -pl parquet-cli spotless:check test` passed: 90 cases, 0 failures/errors, 2 skipped (88 passed), including all seven new cases. Spotless and RAT license checks passed. The module used the existing local dependency cache; no full reactor or multi-JDK build was run. Six temporary local regression checks made the expected assertions fail when footer mode, page column selection/raw mode, or dictionary column selection was ignored. All temporary production edits were restored before the successful full-module run. ### Are there any user-facing changes? No. Tests only. -- This is an automated message from the Apache Git Service.
