Cargo Pretty Test ✨

A Rust command-line tool that prettifies the ugly cargo test output into a beautiful output.

This crate can be also used as a library that fully parses the output from cargo test.

$ cargo pretty-test --workspace --no-fail-fast

---

Run in CI as a summary: demo

      - id: pretty-test
        name: Run cargo pretty-test
        run: |
          cargo install cargo-pretty-test
          cargo pretty-test --color=always
          echo '```text' >> $GITHUB_STEP_SUMMARY
          echo "$(cargo pretty-test --color=never)" >> $GITHUB_STEP_SUMMARY 2>&1
          echo '```' >> $GITHUB_STEP_SUMMARY

Note: --color=always produces texts in color when running CI, and --color=never strips ANSI escapes before written to summary.
