Test UX: High noise to signal ratio in test output for large workspaces.

[gilescope]

rust workspaces are getting bigger and if I run a named test I get this kind of thing:

<snip>

There's screen fulls of this.

Somewhere in the pages of output is my test that was run....

The feature request: Can we have a better UX please?

E.g. could we have a --condenced flag we could use to see more consolidated results because we like tests, lots of tests are good, but the UX could be improved.

Requests like this are what success looks like - it's a good thing :-)

I'd love to see experimentation with this in a third party sub command. When there is a format that is widely used, we can bring it into Cargo.

Yea, I agree it would be nice to have a cleaner summary and output. I'm going to close this as a duplicate of #4324 and #2832.
