Display rollup stats for workspace on cargo test?

[thomasmost]

Problem

Is there any way to get cargo test to output the total number of tests run, ignored, failed, etc (let alone coverage stats) for an entire workspace after running tests for each member on cargo test -- in a workspace? I have a fairly large workspace project with a dozen modules and it would be helpful to see these numbers aggregated

Proposed Solution

with the --rollup flag passed, cargo test would output workspace stats at the end of the test run

  > Rollup: 243 tests run: 241 succeeded — 2 failed — 7 ignored

In the future this flag could also generate coverage reports, but at present I think this would be a simple ergonomic improvement for workspaces

Not exactly the same but #11532 also proposes to have a flag to output a summary for cargo commands. See #11542 for the discussion around that topic.

Feel like this is also blocked on libtest's JSON output. Cargo needs a reliable way to collect such data. See #11875 (comment) for more. In the meantime, personally I'd recommend nextest, which has a handful of goodies for testing user experience.

Thank you! I'll check out nextest — I appreciate it!

Realized today that this is a duplicate of #8414. I'll close this in favor of that. Thank you for the proposal.
