[Feature]: Handle multiline string diffs more cleanly #4511
Description
Problem Statement
The current string diff is great for single-line strings, but when the difference is near newlines, it breaks really bad. For my current project which involves multiline strings as code, it's very hard to make much out of most of the assertion failure text.
Proposed Solution
The best way to represent that would be to show a line-based diff. For example, consider Roslyn's diff implementation, which cleanly shows the differences in the strings, since almost always those are multiline.
My proposal is to show the surrounding 2 lines up and down of each changed line segment, and replace the current "expected ... but found ..." text which is completely useless once the diff is shown.
