**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** - part of https://github.com/apache/arrow-rs/issues/6736 We are implementing Variant, and part of doing so is ensuring that the Rust implementation is compatible with other implementations **Describe the solution you'd like** I would like a harness that 1. For each test listed in `cases.json` 2. Reads the expected variant.bin file and creates a `Variant` from it 3. Reads the data from the Parquet file (should be a StructArray) 4. Construct a VariantArray 5. Read the value from the VariantArray (using both `VariantArray::value` and the `variant_get` kernel) 6. Verify that the value from the VariantArray matches the Variant read from the .bin file Many of the cases will not to pass initially -- that is fine, we should just mark them as `#[ignore]` or something and we will enable them as we work through the Variant implementation **Describe alternatives you've considered** I recommend using this PR from @rdblue - https://github.com/apache/parquet-testing/pull/90 - Here is an example of such an integration test for the go implementation https://github.com/apache/arrow-go/pull/455 written by @zeroshade (`parquet/pqarrow/variant_test.go` specifically) **Additional context** -- This is an automated message from the Apache Git Service.
