As a developer if I am running JUnit tests using the Console Launcher on the command line if two large strings are found to be different and I get "expected:" "but was:" if I want to see what was different I need to copy the strings and manually diff them.

It would be easier if there was --details flag or another flag (I think another flag is a better option) that would show me a diff between the two strings for actionable results. In most cases using an IDE is suitable but in workflows such as Bazel and CI it would be useful if a diff would be displayed.

Apologies if this is already supported didn't find anything obvious in the docs.
