cargo test: Don't re-run tests that already passed · Issue #10673 · rust-lang/cargo (original) (raw)

Problem

I have a large workspace in which there's a crate with several long-running property tests. This makes cargo test --workspace take unreasonably long in the common case where those property tests haven't been touched.

Proposed Solution

Cache the test results, so that cargo test --workspace can complete quickly in the common case where long-running tests haven't been touched.

Notes
