Yep - no rewriter API in Python but you can use relevant methods on ops directly, etc. (Here's one example: https://github.com/libxsmm/tpp-mlir/pull/1064/files#diff-7aa62724b21b998da9cf032da6e6b77bbdb664258a5dca850f9509a5459646f6R110-R118 - @makslevental has more.)

That should be enough to demonstrate that your test pass is actually running and, if kept simple, will not be that ugly.
