Research direction

Start by locating the assertion and error-reporting code in the rules_testing repository; the issue does not name a file or test. Reproduce comparisons involving a large string and a large collection, then verify that failures show a readable diff highlighting differences between expected and actual values.

Written by the indexing model from the issue text.

Description

enhancement

When large objects are compared, it makes the resulting errors hard to visually see what the differences are. This occurs with both large strings (e.g. generated BUILD file content for repository rule utilties) and large collections (e.g. the argv of a cc link command).

A diff would help draw attention to the parts of the expects vs actual that actually differ.
